At a glance

This is the Lex Fridman Podcast episode 475, the second appearance of Demis Hassabis, the Nobel Prize winning leader of Google DeepMind. For roughly two and a half hours Fridman and Hassabis push on one idea from every side: that the universe is built out of information, that most of nature is therefore learnable by ordinary computers, and that this is why systems like AlphaFold and Veo 3 work at all. From there they walk the whole map, the P versus NP question as a physics question, video games as co created worlds, AlphaEvolve and evolutionary search, the dream of a simulated cell, the origin of life, a fifty percent bet on AGI by 2030, scaling laws, compute, fusion and solar, the war for talent, the future of programming, John von Neumann, p(doom), and consciousness.

Hassabis argues for a specific worldview. Nature has structure because it was shaped by selection over billions of years, so its patterns are not random, so a neural network can find the low dimensional manifold that generated them. That is why protein folding turned out to be tractable on classical machines, and it is the seed of a possible new complexity class he is quietly working on in his spare time. Fridman keeps pulling the conversation toward the deepest mysteries, life, time, consciousness, and Hassabis keeps insisting that building artificial intelligence is the sharpest tool humanity has ever had for answering them. The final half hour is Fridman alone, on David Foster Wallace, attention, and a personal note about his years at MIT and Drexel. This page rebuilds the entire conversation in order, keeps the numbers and named systems, and turns the core ideas into diagrams you can read.

The deep explanation

The Nobel conjecture: any pattern nature can make, a classical machine can learn

Fridman opens on a line from Hassabis's Nobel lecture, a deliberately provocative conjecture: any pattern that can be generated or found in nature can be efficiently discovered and modeled by a classical learning algorithm. Hassabis says being a little provocative is a tradition of Nobel lectures and he wanted to honor it. Step back and look at the Alpha X projects, AlphaGo and AlphaFold, and what they really do is build models of combinatorially enormous spaces. If you tried to brute force the best move in Go or the exact shape of a protein by enumeration, there would not be enough time in the lifetime of the universe. Instead both systems learned a model of the environment that guides the search and makes it tractable.

Why should that even be possible? Proteins fold in milliseconds inside our bodies, so physics already solves the problem that AlphaFold now solves computationally. Hassabis's answer is that natural systems have structure because they were subject to evolutionary processes that shaped them, and if that is true the structure can be learned. He calls the general version survival of the stablest. There is evolution for living things, but there is also geological time shaping mountains through weathering over thousands of years, and cosmological time shaping the orbits of planets and the shapes of asteroids. Everything around us, even the more stable chemical elements, has survived some selection pressure, so it carries a non random pattern that a network can reverse learn as a manifold that guides the search to the right answer. The exception is man made or abstract things such as factoring large numbers. If the number space has no pattern and is uniform, there is nothing to learn and you are back to brute force, which is where a quantum computer might be needed. But most of nature is not like that.

about 10^300 possible unfolded shapes native folded state the one structure physics finds in milliseconds free energy the funnel is the learnable manifold
Figure 1. Hassabis's core intuition. The space of possible protein shapes is larger than the number of atoms in the universe, yet a real protein slides down an energy funnel to one native structure in milliseconds. Because selection carved that funnel, its shape is a low dimensional manifold a classical neural network can learn and descend, which is why AlphaFold works and why he thinks most of nature is efficiently modelable.

Information as the fundamental unit, and P versus NP as a physics question

This leads Hassabis to a proposed new complexity class, a set of learnable natural systems, alongside the classic entries in the complexity zoo. It is exactly what he says he works on in his few spare moments with a few colleagues: whether there is a class of problems solvable by this kind of network mapped onto natural systems that have physical structure. It fits how he thinks about physics in general. Information is primary, more fundamental than energy and matter, all convertible into each other, with the universe best understood as an informational system. If physics is informational, then P versus NP becomes a physics question, and its answer would be enlightening.

Fridman notes the pattern: Christian Anfinsen said something that sounded crazy in his own Nobel speech, and decades later Hassabis and John Jumper got a Nobel for solving the folding problem it pointed at. Hassabis thinks a huge class of problems can be couched the AlphaGo and AlphaFold way, where you model the dynamics of the system so that the search for a solution or the next step becomes efficient, effectively polynomial time and tractable on a classical Turing machine, which is what a neural network runs on. The AI community has already shown classical systems can go much further than people thought a decade or two ago, when many assumed protein folding might need quantum machines. AGI built as a neural network on a neural network on a classical computer would be the ultimate expression of that, and the bounds of what such a system can do speak directly to P versus NP.

They probe the edges. Cellular automata and most emergent systems are probably modelable by a forward simulation, sitting right on the boundary; genuinely chaotic systems, where initial conditions dominate and the end state is uncorrelated, are the hard case. Even highly nonlinear dynamical systems and fluids, the Navier Stokes regime traditionally thought intractable and compute hungry, may surprise us. Fridman brings up his conversation with Terence Tao about singularities that break the mathematics, and Hassabis points at Veo, which models liquids, materials, and specular lighting surprisingly well. He used to write physics and graphics engines in his gaming days and knows how painstaking that was, yet these models reverse engineer it from watching YouTube videos, presumably by extracting a lower dimensional manifold of how materials behave. Maybe, he says, that is true of most of reality.

Veo 3 and what it means to understand reality

The physics is what fascinates Hassabis about Veo 3, more than the comedy, the native audio, or the uncanny realism of the humans. It is not perfect but it is pretty good, and the real scientific question is what the model has to understand to do it. A cynic says a diffusion model understands nothing, but you cannot generate coherent video like that without some form of it, which drags our own philosophical notion of understanding to the surface. Hassabis draws the line carefully: to the extent it can predict the next frames coherently, that is a form of understanding, not the deep anthropomorphic kind, but enough modeled dynamics to produce eight seconds of consistent video that is hard to fault at a glance. Wind that forward two or three years. He calls it intuitive physics, the way a human child grasps that a pushed glass shatters and spills, rather than a PhD unpacking the equations. It is the base layer people call common sense.

That result challenges a belief Hassabis himself held. Theories of action and perception in neuroscience say you need to act in the world, through embodiment or robotics or at least simulated action, to truly perceive it. Five or ten years ago he would have agreed you need that to learn intuitive physics. Yet Veo learns it through passive observation, which he finds surprising and, again, a hint about the underlying nature of reality. The next stages make those videos interactive, so you can step in and move around, which given his games background would be mind blowing, and takes you toward what he calls a world model, a model of the mechanics of the world and the things in it, which is exactly what a true AGI needs.

Video games: open worlds, co creation, and the dream unbuilt

Fridman brings up a post on X from Jimmy Apples asking for playable world models built from Veo 3 videos, which Hassabis quote posted with "Now, wouldn't that be something?" Games were his first love and his first professional AI work as a teenager. He dreams about what he could have built in the 1990s with today's systems. His favorite genre is the open world game, a simulation plus AI characters plus a player whose actions the simulation adapts to, so every player co creates a unique experience. He worked on Theme Park at Bullfrog, where each player's game was their own. The problem is that open worlds are hard to author because you must have compelling content in whatever direction the player goes, and the classical cellular automata tricks that gave emergent behavior were always fragile and limited. Now, within five to ten years, AI may be able to generate a dramatic narrative on the fly around whatever the player chooses, the ultimate choose your own adventure, an interactive Veo wound forward.

Fridman sharpens the point. Real open world design is not the illusion of choice that The Stanley Parable satirizes, nor the two hardcoded doors of most games, but a world where opening any door genuinely defines what you see. He loved the random dungeon generation of The Elder Scrolls II: Daggerfall, where you might be the only person to ever see a given room. Hassabis wants better than random and better than a hardcoded A or B branch, which requires generative systems producing content on the fly, since you cannot pre build infinite assets and AAA games are already expensive. He points to Black & White, which had an early reinforcement learning creature you nurtured, and which mirrored your behavior toward the villagers, mean if you were mean, protective if you were good. His whole career is a follow on from those hardcoded beginnings to fully general learning systems chasing the same goal.

He and Elon Musk are both gamers itching to build a game. The sad irony is that success in serious science may leave him only building the tools others use to make the game he dreamed of. Two ways out: vibe coding good enough to build one in his spare time, which he is itching to try, or a post AGI sabbatical after the technology is safely stewarded into the world, alongside his physics theory. Asked to choose between solving P versus NP and making a game, he says in his world they are the same question, because the ultimate game would be an open world simulation as realistic as possible, which is just another way of asking what the universe is. Games get looked down on, but as AI absorbs the boring work we call jobs, games may be where humans find meaning and richer, more diverse ways of living. His favorite game of all time is Civilization, specifically Civ 1 and Civ 2, and he has avoided the latest one because it would consume him. He learned to program on a ZX Spectrum and then his beloved Commodore Amiga 500, in a UK era when the forefront of computing, AI, graphics, physics engines, and even GPUs, was being pushed forward by games fused with art.

AlphaEvolve: language models proposing, evolution searching

Hassabis calls AlphaEvolve one of the most underappreciated recent results. It is a Google DeepMind system that evolves algorithms: the evolutionary process does the search while a large language model proposes where to look. He frames it as a template, foundation models combined with other computational techniques, evolutionary computing here, but also Monte Carlo tree search or other reasoning algorithms layered on top. The pattern is always a model of the system's dynamics plus a search on top to reach a novel region. AlphaGo used Monte Carlo tree search, and that is how it found move 37, a never before seen Go strategy, going beyond everything already known. Bolt a fairly simple search onto a good model, add an objective function to hill climb, and you can reach genuinely new discoveries, which is the point for science and medicine.

What excites him is that evolution is good not just at natural selection but at combining components and building increasingly complex hierarchical systems through mutation and recombination, in the space of programs, which generalizes almost everything. The historical limit is that traditional evolutionary methods, well studied in the 1990s and 2000s, could never evolve genuinely new emergent properties, only reshuffle the ones you put in. Natural evolution clearly overcame that, going from bacteria to us, so combining it with foundation models might finally unlock new emergent capabilities. Fridman keeps a Tiktaalik skull on his desk, one of the early creatures that crawled from water onto land, as a daily reminder of what a relatively simple algorithm produced over four billion years running on the physics substrate of the universe.

language model proposes candidates evolve mutate + recombine program variants objective function score, keep the best, hill climb survivors feed the next round novel region of the space a "move 37"
Figure 2. The hybrid pattern Hassabis keeps returning to. A foundation model proposes, a search process (evolutionary here, Monte Carlo tree search in AlphaGo) explores, and an objective function selects. The loop hill climbs a known landscape but, run long enough, can jump to a genuinely novel region, the kind of leap that produced move 37.

Research taste, conjectures, and splitting the hypothesis space

Fridman raises the AI 2027 essay by Daniel Kokotajlo, Scott Alexander and others, which sketches steps toward superintelligence through a superhuman coder and a superhuman AI researcher, and its notion of research taste. Can an AI system have taste? Hassabis thinks this is the hardest thing to mimic, the judgment that separates great scientists from merely good ones, all of whom are technically competent. Taste is sniffing out the right direction, the right experiment, the right question, and picking the right question and hypothesis is the hardest part of science, which today's systems cannot do. His refrain: it is harder to come up with a really good conjecture than to solve it. Systems may soon solve hard conjectures, and AlphaProof already reached silver medal level on International Mathematical Olympiad problems, perhaps one day a millennium prize problem, but coming up with a conjecture that Terence Tao would call a deep question about the nature of mathematics is a far harder creativity, the leap of imagination Einstein made toward special and then general relativity.

A good conjecture, they agree, hits a sweet spot: interesting, falsifiable, amenable to proof with available technology, and splitting the hypothesis space roughly in two so that either outcome teaches you something. That is why Hassabis says there is no such thing as failure in real blue sky research, as long as your experiments and hypotheses meaningfully split the hypothesis space. A well designed experiment that does not work tells you as much as one that does, and the whole enterprise is a search that uses that information to decide where to go next, essentially a binary search through ideas.

The virtual cell: simulating a biological organism

Hassabis's method is to take a grand dream and break it into achievable, individually useful steps. The virtual cell is a dream he has held for about twenty five years, discussed since the 1990s with his biology mentor Paul Nurse, who founded the Francis Crick Institute and won a Nobel Prize in 2001. The goal is to model enough of a cell's internals to run experiments in silico, potentially a hundredfold speedup, with the wet lab reserved for validation. He would start with a yeast cell, which Nurse studied, because it is a full organism that is also a single cell, the simplest case, and very well understood.

AlphaFold gives the static picture, the 3D structure of a protein. The interesting biology is in the dynamics and interactions, which is what AlphaFold 3 begins to model, first pairwise, proteins with proteins, RNA and DNA. The next step would be a whole pathway, perhaps the TOR pathway implicated in cancer, and then eventually a whole cell. A cell operates at many time scales, so you would need several interacting simulations or a hierarchical system that can jump up and down the temporal stages. A key modeling decision is the granularity cutoff, and for a cell Hassabis hopes the protein level is enough, without going down to the atomic or quantum level, with AlphaFold as the basis and higher level simulations built on top to give emergent behavior. AlphaGenome, which predicts how small genetic changes link to function, is another piece creeping toward that complexity.

Figure 3. The Alpha X lineage the conversation keeps circling, from Hassabis's game AI in the 1990s to the 2024 Nobel and the flood of 2025 systems. Each one is the same recipe applied to a new natural system.

The origin of life and the continuum from physics to biology

Could AI help simulate the origin of life, the birth of a living organism from non living chemistry? Hassabis loves this area and recommends Nick Lane and his book Life Ascending: The Ten Great Inventions of Evolution, which also bears on where the great filter might lie. He suspects the filters are mostly behind us, given how unlikely any life at all seems, and how the jump from single cell to multicellular life took roughly a billion years, with bacteria content for a very long time before one captured mitochondria through endosymbiosis. He sees no reason AI could not help by searching a combinatorial space: give it the primordial chemical soup near hydrothermal vents and some initial conditions, and see if something cell like emerges. Fridman wishes for a move 37 for the origin of life, and they converge on the idea that there may be no real line between non living and living, only a continuum connecting physics, chemistry and biology, the same process running from the Big Bang to today.

This is Hassabis's whole reason for working on AI: the ultimate tool for answering questions we still cannot answer, like a rigorous definition of life, the nature of time, consciousness, gravity, and quantum weirdness. He says these mysteries have been screaming in his face since childhood, and getting louder. Humans have always coped with deep mysteries, the sun, the rain, by staying busy, arguably distracted. Weather is the classic hard, near chaotic system, and Google DeepMind has built the best weather prediction systems in the world with WeatherNext, better than traditional fluid dynamics run on supercomputers that take days, including recent cyclone track prediction that matters enormously and must be fast as well as accurate. Fridman connects this to the storm chasers he met in Texas, extremely tech savvy people who ride the edge between living organisms in the eye of the storm and the cutting edge of forecasting, and who might one day use a DeepMind model. Hassabis would love to join a chase.

The path to AGI: a 2030 bet and the tests that would prove it

Hassabis puts a fifty percent chance on AGI within five years, so by around 2030. Much depends on the definition, and his has always been a high bar: matching the cognitive functions of the human brain, which is close to a general Turing machine and built modern civilization. To call something a true AGI, it would have to have all those capabilities consistently, not be a jagged intelligence that is brilliant at some tasks and badly flawed at others, which is exactly what today's systems are. It would also need the invention and creativity capabilities that are currently missing. One test is brute force: tens of thousands of cognitive tasks humans can do. Another is to hand the system to a few hundred of the world's top experts, the Terence Taos of each field, for a month or two, and see if they can find an obvious flaw. If they cannot, you can be fairly confident it is general.

Fridman pushes back that humans quickly take new capabilities for granted and zero in on the one flaw, and that even brilliant humans have limits across domains. Hassabis agrees there are also lighthouse moments he would watch for, move 37 style. One would be inventing a genuinely new conjecture or hypothesis about physics the way Einstein did, and you could even back test it by giving the system everything known up to a 1900 knowledge cutoff and seeing whether it derives special and general relativity. Another would be inventing a game as deep, elegant and beautiful as Go, not just a new move within Go. A system that could do several of these, plus pass the consistency checks, would be his sign of AGI. If it produced a real new discovery, he imagines being in the room, two or three months before announcing, trying not to tweet, validating it with world experts while the system explains its own workings. He is not worried it would be totally mysterious to the best scientists, giving the chess analogy that Garry Kasparov or Magnus Carlsen can explain a brilliant move afterward even if you could not have found it, and that explaining simply is itself part of intelligence.

On recursive self improvement, AlphaEvolve shows the shape of it, but Hassabis is cautious and not even sure end to end self improvement is desirable, since that is a hard takeoff scenario. Current systems keep a human in the loop, and today's models cannot design their own architecture from a vague, high level instruction. "Invent a game as good as Go" or "make a better version of yourself" is too underspecified, whereas honed tasks like faster matrix multiplication they handle well with incremental improvement. Fridman offers a softer path, a long sequence of incremental gains that slows as it goes, giving a gradual set of S curves rather than an explosion. The open question is whether these systems could ever produce a leap like the Transformer architecture in 2017, and Hassabis is honest that no one has shown systems that make those big leaps yet, only ones that hill climb the S curve they are already on. That leap would be the move 37 of AGI.

Scaling laws, compute, and whether progress hits a wall

Hassabis sees plenty of room left, and importantly across all three scalings happening at once, pretraining, post training, and inference time. It comes down to how innovative you can be, and he prides Google DeepMind on the broadest and deepest research bench, naming Noam Shazeer of Transformer fame and David Silver who led AlphaGo. If a new breakthrough on the order of AlphaGo or Transformers is required, he would back his team to produce it, and he actually prefers it when the terrain gets harder because that shifts the work from engineering toward research, their sweet spot. He puts it at roughly fifty fifty whether new ideas are needed or whether scaling the current approach is enough, and pushes both hard, with about half of resources on blue sky ideas. He notes that over the last ten to fifteen years something like eighty to ninety percent of the breakthroughs underpinning modern AI came from Google Brain, Google Research and DeepMind. On data he is not worried about running out of high quality human data, partly because simulations can generate synthetic data from the right distribution once you have enough real world data to build the generators, which is where he thinks we are now.

Compute is crucial and increasingly geopolitical, entangled with supply chains and energy. Training needs co located compute, and even bandwidth between data centers is a constraint. But now that AI systems are in products used by billions, inference compute is enormous, and the new thinking systems get smarter the more inference time you give them at test time, so training may become the smaller part of the total. The Veo 3 success spawned a meme about sweating servers, and DeepMind made a joke video of servers frying eggs. On hardware they push their TPU line, including inference only chips, and they build AI to cut energy use: data center cooling efficiency, grid optimization, plasma containment for fusion reactors with Commonwealth Fusion Systems, reactor design, and materials design for new solar materials, room temperature superconductors and optimal batteries, any one of which would be revolutionary. He thinks AI could materially help with these within five years.

The future of energy and radical abundance

Asked to bet on the main energy source in twenty or thirty years, Hassabis picks fusion and solar. Solar is the fusion reactor in the sky, and its real problems are batteries and transmission, plus more efficient materials, perhaps eventually space based solar or Dyson sphere ideas. Fusion is doable with the right reactor design and fast enough plasma control. Both get solved, giving clean, renewable, almost free energy. On a hundred year scale he would not be surprised to reach a type one Kardashev civilization. Cheap clean energy cascades: water access is solved by desalination, currently too expensive for all but wealthy coastal states like Singapore and Israel; you get effectively unlimited rocket fuel by splitting seawater into hydrogen and oxygen, which combined with self landing rockets turns space into a bus service; asteroid mining becomes real; and you approach Carl Sagan's vision of waking up the universe by bringing consciousness to it. A tourist flying past Earth would see traffic in space like London traffic, floating solar, a more technological surface, and the surplus energy used to preserve nature. For the first time humanity would not be resource constrained, breaking the zero sum trap into a radical abundance era, after which the big question becomes distributing that abundance fairly.

Human nature: games, conflict, and the meaning of mastery

Fridman notes a stubborn fact about human nature, the Borat style neighbor who starts trouble, that we do start conflicts. Games throughout history, he is learning, served to channel that away from hot war, and with civilization ending weapons now available it is far better to fight over a chessboard or a football pitch. Hassabis loves football as a visceral, tribal outlet that meets a human need to belong in a healthy, constructive way. He argues games like chess are great for children because they are microcosm simulations of the world, simplified versions of real situations, poker, Go, chess, diplomacy, where you can practice decision making. You only get a dozen or so genuinely big life decisions, so a safe, repeatable environment to improve your decision process is valuable. Just as important is practicing losing and winning. Fridman brings up Brazilian Jiu Jitsu, where you get your ass kicked safely and are reminded that losing is a fundamental part of life, and you can still be friends afterward. Hassabis says martial arts and chess, done in a healthy way, are about self improvement and self knowledge rather than the other person, not getting carried away by victory and staying humble through losses, always knowing there is more to learn. The deepest source of meaning is mastery, the number going up on the skill tree, the color belts, the quiet joy of doing something you could not do before, and games and sports are beautiful precisely because they measure that progress in creatures who are themselves hill climbing systems.

Google and the race to AGI: from losing to winning, and the art of the interface

A year ago, with Gemini 1.5, Google was widely seen as losing on the LLM product side; now, with Gemini 2.5, it is winning, and Hassabis took the helm. He credits an absolutely world class team, naming Jeff Dean and Oriol Vinyals among the Gemini leadership, plus great compute, and above all a research culture built by merging Google Brain with the old DeepMind and pulling together the best people and ideas. His mantra is relentless progress plus relentless shipping of that progress. On the bureaucracy of a giant company, he still runs Google DeepMind like a startup, large but decisive, chasing the best of both worlds, world class research plugged into product surfaces that reach billions the next day, while continually cutting away bureaucracy so the research and shipping cultures can flourish responsibly.

He tells a humbling story about scale. Irving Finkel, the British Museum cuneiform expert, has never heard of ChatGPT or Gemini, and his first encounter with AI is AI Mode in Google Search. A large part of the world has not met this technology yet, even as X feeds and pockets of the valley think about nothing else, which makes that first interaction a real responsibility, whether in rural India or anywhere, often as invisible improvements under the hood of Maps or Search. The Gemini team praised Hassabis as a great product person, which he traces to designing games for millions in the 1990s, the same fusion of cutting edge technology and product, and the same reliance on taste. He sees no boundary between art and science or product and research, only a continuum, and only works on products with cutting edge technology under the hood.

His product lessons: continually simplify and get out of the way of the model, because the model train is coming down the track and improving unbelievably fast, 2.5 versus 1.5 being a gigantic jump. You have to design not for what the technology can do today but for what it will do in a year, which makes you a deeply technical product person judging whether the research track will intercept your dream in six months or a year. He doubts the text box chat will survive contact with truly multimodal systems, expecting something more like Minority Report where you vibe collaboratively, and predicts we will look back on today's interfaces as archaic within a couple of years. Typing is low bandwidth, so he expects smart glasses, audio earbuds, and eventually neural devices to raise input and output bandwidth perhaps a hundredfold. Interface design is an underappreciated art form that unlocks the intelligence underneath, and he invokes Steve Jobs and the pursuit of simplicity, beauty and elegance, an interface as beautiful as Go, and foresees AI generated interfaces personalized to your aesthetic and the task, minimal for some, every parameter exposed for keyboard driven power users like Fridman.

On version numbers and the road to Gemini 3, he explains the cadence. Roughly every six months they collect the best research ideas on architecture and data, package and test them, then start a giant hero training run, followed by pretraining and an extensive post training and experimentation phase where a lot of the gains come. Version numbers refer to the base pretrained model, while interim 2.5 releases are usually patches or post training on the same architecture, and the sizes, Pro, Flash and Flash Lite, are often distilled from the biggest, Flash from Pro. They think in terms of a Pareto frontier of performance against cost and latency, aiming to have a model on every point of that frontier so any user or developer finds one that fits. Cool side quests like Veo spin off along the way, but you cannot take too many or you drown in versions, so they keep converging upstream, folding ideas from product surfaces and post training back into the core model training for the next run, which makes the main Gemini track more general and, eventually, AGI. One hero run at a time.

cost and latency (speed, price) performance dominated Flash Lite Flash Pro distilled from Pro
Figure 4. How Hassabis describes the Gemini family. Performance rises with cost and latency, and the sizes sit along a frontier so that whatever trade off a user or developer wants, one model satisfies it. Flash and Flash Lite are distilled from the biggest Pro model rather than trained separately.

Benchmarks, he says, are necessary but must not be overfit. He cites LMArena as the way that organically became a main test for chatbots, alongside academic benchmarks for math, coding, language and science, and their own internal suite. It is a multi objective optimization, and they aim for no regret improvements, gains in coding that do not degrade translation or other capabilities, which is the hard part, since more of one kind of data can quietly hurt another. Ultimately they trust direct usage signals from real users, because usefulness is hard to reduce to a number, a vibe across many people, and it would be terrifying to ship a smarter model that just feels off. Even more esoteric is persona and style, whether the system is verbose, succinct or humorous, which drifts into the personality research Hassabis did in his PhD, the five factor model, and raises genuinely new product questions about what an assistant should be like, which people can partly steer through prompt engineering. Asked the probability of Google DeepMind winning, he rejects the frame, calling winning the wrong way to look at something this consequential; the job is to steward the technology safely into the world for the benefit of humanity, and he hopes the international community rallies around that as AGI nears. He stays deliberately collaborative and on good terms with the other lab leaders, keeping communication channels open for cooperation on safety, and wishes more labs used AI for science the way DeepMind does, pointing to AlphaFold and to Isomorphic Labs, spun out of it to accelerate drug discovery.

Competition, the war for talent, and the future of programming

On the talent war and Meta paying huge salaries, Hassabis is measured. He thinks the real believers in the AGI mission mostly want to be on the research frontier so they can influence how it goes, and Meta is not currently at that frontier, so its aggressive hiring is rational for a company that is behind. There are more important things than money, though people must be paid market rates, which keep rising. He has known for thirty plus years that AGI is probably the most important technology ever, and it is striking that leaders are only now realizing it. He remembers not paying himself for a couple of years when DeepMind started in 2010 and could not raise money, whereas interns today are paid what his entire first seed round was; the world has inverted. And he keeps returning to the bigger question of what money will even mean post AGI, when energy is solved and the economy has to be rethought.

On jobs, programming is the sharp case, because AI is already strong at it and improving. Counterintuitively, coding and math turned out easier for AI because you can generate synthetic data and verify its correctness. For the next five to ten years, he thinks people who embrace these tools and become at one with them, in creative or technical fields, become superhumanly productive, and the great programmers become even better, perhaps ten times what they are today, by exploiting the tools fully. Cheaper coding opens programming to far more creatives, while the top programmers keep a large advantage in specifying architecture, framing questions, guiding coding assistants and checking their output. Value shifts, front end web design may be more automatable than game engine design or high performance back end work, which moves where humans are needed most and is scary to adjust to. He compares the disruption to the internet, mobile and the Industrial Revolution, with new jobs we cannot yet imagine, but warns this time it may be ten times the impact of the Industrial Revolution and ten times faster, ten years rather than a hundred, a combined hundredfold that society will find hard to absorb. He urges economists and philosophers to think now about ideas like universal basic provision, sharing the productivity gains as services with a basic floor, while rare skills still command more. Fridman broadens it to government as a technology that must adapt to represent people's pain without fueling division, and Hassabis agrees new governance structures and institutions will be needed, but insists the first job is to create abundance, because you cannot distribute what does not yet exist.

John von Neumann and the mad dreams of reason

Hassabis recommended Fridman the book The MANIAC by Benjamín Labatut, which even contains a strange biographical thread about Hassabis himself, blurring fiction and reality, but whose central figure is John von Neumann. Von Neumann contributed to quantum mechanics, worked on the Manhattan Project, and pioneered the modern computer and AI through the von Neumann architecture that all our machines still use. He watched physics become the atomic bomb and foresaw a similar arc for computing. Hassabis would love to meet him, praising his time at Princeton's Institute for Advanced Study, his polymath range and his foresight, and guesses von Neumann would have loved AlphaGo, having done game theory, and would barely be surprised, having foreseen learning machines that are grown rather than programmed back in the 1950s. He suspects there is lost wisdom from that era about dialogue and picking up the phone to talk to those the politicians call enemies. AI, he stresses, is a multi use technology aimed at curing disease and solving energy and scarcity, but with real risks, and von Neumann probably foresaw both, telling his wife computers would be even more impactful than the bomb.

A takeaway from the book, they agree, is that reason alone, the mad dreams of reason, is not enough to guide humanity as it builds powerful technology; there is something else, a spiritual or humanist dimension that pulls at the human spirit in a way cold reason does not. Hassabis embraces that, not necessarily as religion but as a sense of soul, of the spark that makes us human, perhaps consciousness itself. He casts technology as the enabler, the tools that let us flourish and understand, and sides with Richard Feynman that science and art are companions, that knowing why a flower's colors evolved makes it more beautiful, not less. He points to the Renaissance and Leonardo da Vinci, who saw no boundary between science, art and the sacred, and names Spinoza as a favorite philosopher for uniting the drive to understand the universe with our place in it. He worries many researchers in the field are too narrow and only understand the technology, which is why he welcomes society debating AI, the AI summits, governments engaging, and the chatbot era letting ordinary people feel cutting edge AI for themselves. Asked whether there will be a Manhattan Project style escalation, states weaponizing the technology, he hopes not, preferring something more like CERN, a research focused effort where the best minds complete the final steps responsibly before deployment, and he argues for education and immigration flowing both ways between the West and China so human ties make it harder for warmongers to divide us, with science as the connector.

p(doom): cautious optimism under deep uncertainty

Hassabis refuses to give a p(doom) number, calling the precision it implies a little ridiculous and questioning how people even derive theirs. What he will say is that the risk is definitely nonzero and probably not negligible, which is sobering, and that everything is hugely uncertain: what these systems will do, how fast they take off, how controllable they are. Some things may prove far easier than feared, others far harder. Given huge stakes both ways, curing disease, solving energy and scarcity, reaching the stars on one side, and catastrophe on the other, the only rational stance is cautious optimism. He would actually be more worried for humanity if AI were not coming, because climate, disease, aging and resources look hard to solve without it. The right response is the scientific method, more research to define and address the risks precisely, and he thinks that effort needs to be perhaps ten times larger than it is now as we approach the AGI line. He splits the danger into two: bad actors repurposing a general purpose technology, which sits in tension with his instinct for open science and open source, since it is genuinely hard to give good actors access while restricting individuals or rogue states; and, on a different time scale, increasingly agentic and autonomous systems whose guardrails must hold. AI itself might help, giving early warning on biological or nuclear misuse, as long as the AI you rely on is itself reliable, an interlocking problem that may need at least basic standards agreed between the United States and China.

What makes humans special, consciousness, and the friendly disagreement with Penrose

Returning to The MANIAC, they discuss Lee Sedol's move 78, the hand of God move in game 4, perhaps the last time a human's pure genius beat AlphaGo, a moment where human and machine seemed to inspire each other, captured in the documentary. What makes humans special as AI improves? It feels, perhaps with bias, that we are deeply special, and maybe it is not our intelligence but something outside the mad dreams of reason. Hassabis did a neuroscience PhD on imagination and memory in the hippocampus, and always believed that building an intelligent artifact and comparing it to the human mind is the best way to uncover what, if anything, is special about us. He suspects something is, and expects this journey to help define it, including any difference between carbon and silicon substrates processing information. One definition he likes: consciousness is the way information feels when we process it, not a rigorous scientific explanation but an intuitive one.

Fridman invokes Feynman, "what I cannot create I do not understand," and turns to Roger Penrose. Is consciousness a computation, and if it is information processing, is it modelable by a classical computer or is it quantum mechanical? Hassabis calls Penrose one of the greatest thinkers of the modern era and says they cordially disagree. Penrose collaborates with neuroscientists to find quantum mechanical behavior in the brain and, to Hassabis's knowledge, they have not found anything convincing, so his bet is that the brain is mostly classical computing, which would mean all its phenomena are modelable or mimicable by a classical computer. There may still be a final mystery, the felt quality of consciousness, the qualia, that is unique to the substrate, and we might approach understanding it through neural interfaces that let us feel what it is like to compute on silicon. He recounts a debate with the late Daniel Dennett about why we assume each other are conscious: partly shared behavior, but also, often overlooked, that we run on the same substrate, which makes it parsimonious to assume you feel what I feel. With a silicon AI we lose that second reason; even if it behaves conscious and claims to be, we would not know how it felt, and it could not know how we feel, at least until superintelligence perhaps bridges the gap.

QuestionHassabisPenrose
Is consciousness computation?Yes, information processingNot ordinary computation
Substrate of the mindMostly classical computing in the brainQuantum effects in neurons
Modelable by a classical computer?Yes, phenomena are mimicableNo, needs new physics
Evidence so farNo convincing quantum mechanism found in the brainSearching with neuroscientists for one
The remaining mysteryQualia may be unique to the substrate; feel it via neural interfacesConsciousness is fundamental and non computable
Figure 5. The cordial disagreement at the heart of the final act. Hassabis bets the brain is a classical machine, so its behavior, and perhaps eventually its feelings, are modelable; Penrose holds that consciousness needs physics beyond computation. Both agree we do not yet have the answer.

This demands what Fridman calls radical empathy, the ability to empathize across a different substrate, something humanity has never had to confront. Brain computer interfaces might let us truly feel what it is like for information to be computed on something other than carbon. Hassabis notes we already extend some empathy to higher animals, killer whales, dolphins, dogs, monkeys and elephants, which have aspects of consciousness even without high IQ, and mentions DolphinGemma, a version of their system trained on dolphin and whale sounds that might one day become a translator. What gives him hope is the almost limitless ingenuity of the best human minds, and human adaptability, the fact that hunter gatherer brains built for the tundra now fly on planes, record podcasts and inhabit virtual simulations, and have already absorbed talking to chatbots as normal. Fridman jokes that this very podcast may be replaced by AI and that he is waiting for it, and closes grateful for the human capacities for curiosity, adaptability, compassion and love, calling Hassabis one of the truly special humans in the world.

Coda: Fridman on David Foster Wallace, MIT, and Drexel

The last half hour is Fridman alone. Prompted by the twentieth anniversary of the This Is Water commencement speech David Foster Wallace gave at Kenyon College, he calls it one of the greatest and most unique such speeches ever, alongside the one by Steve Jobs, and Wallace one of his favorite writers, a man whose tragic honesty read like notes from the front lines of a battle with his own mind. He retells the parable of the two young fish who do not know what water is, and Wallace's point that the most obvious, important realities are the hardest to see and talk about, a banal platitude that can carry life or death importance in the trenches of adult existence. His takeaways: question everything, especially your basic assumptions, a deeply personal project; the central spiritual battles are fought in mundane daily moments, not on a mountaintop; and we too easily surrender our attention to distractions, the insatiable black holes of attention, when the call is to find meaning in the mundane and to be, in Wallace's phrase, unborable. He connects it to Feynman's flower, that a scientist sees more beauty in a flower than an artist alone, not less, and to Wallace's Alaskan bar story about the atheist and the religious man, whose lesson is that everything is a matter of perspective and that wisdom needs the humility to keep expanding it.

Fridman then speaks candidly about being attacked and lied about online, which breaks his heart but which he accepts as the cost of the path he has chosen. He states the facts about a recurring attack: he proudly earned his bachelor's, master's and doctorate at Drexel University, and he has been a paid research scientist at MIT for over a decade, from 2015 to today, in LIDS, the Laboratory for Information and Decision Systems, listed in the directory, with peer reviewed papers on his Google Scholar profile. He taught many lectures for fun, not as research, worked intensively his first four years, took leave in 2019 for AI and robotics projects and the podcast, and has not actively published since 2020 because, like the podcast, real research is a full time effort, which eats at him because building systems that people use is a genuine source of happiness he hopes to return to. At Drexel he took hard math and theoretical computer science courses, programmed robots, optimization, computer vision, wireless protocols and simulations in C and C plus plus, fell in love with programming, Emacs and the Kinesis keyboard, played guitar, wrote crappy poetry, and trained Judo and Jiu Jitsu that humbled him daily through his twenties. He closes by hoping people caught up in online mobs do not lose themselves, insisting there is more good than bad in people, admitting he is flawed, human, and that we are all in this beautiful mess together.

The following is a conversation with Demis Hassabis, his second time on the podcast. He is the leader of Google DeepMind and is now a Nobel Prize winner. Demis is one of the most brilliant and fascinating minds in the world today working on understanding and building intelligence and exploring the big mysteries of our universe. This was truly an honor and a pleasure for me. And now a quick few second mention of a sponsor. Check them out in the description or at lexfridman.com/sponsors. It's the best way to support this podcast. We got Hampton for connecting with founders and CEOs, Finn for AI customer service, Shopify for building e-commerce businesses, Element for daily electrolytes, and AG1 for your health. Choose wisely, my friends. And now on to the full ad reads. I do try to make them interesting, but if you must skip, friends, please still check out our sponsors. I enjoy their stuff, maybe you will, too. And also, to get in touch with me for whatever reason, go to lexfridman.com/contact. All right, let's go. This episode is brought to you by Hampton, a private community for high-growth founders and CEOs. That's the interesting thing about starting a company and running a company, especially one that's growing really quickly, has to hire a lot, has to scale a lot. It's perhaps a little bit counterintuitive, but for the founder, it can be deeply lonely. I suppose that's one of the reasons they recommend to have a co-founder, but even outside of that, there's just a deep loneliness with putting it all on the line, risking everything, knowing that the chances of success are low. But if you do succeed, the gains are huge, and you have your heart in it, you have your dreams in it, you believe in it, but also there's a constant roller coaster of fear and doubt and hope and moments of triumph, and moments of failure. All those go back and forth and just this is a constant psychological turmoil. Anyway, through all that, it's just nice to connect with other people that are going through the same thing, and that's what Hampton is about. It does a thing where every month eight founders face-to-face have real conversations about their daily struggles. Groups are forming in a bunch of places, New York City, Austin, San Francisco, LA, Miami, Denver, and so on. If you are a founder who's tired of carrying it all alone, visit joinhampton.com/lex to see if it's a fit for you. That's joinhampton.com/lex. This episode is also brought to you by Finn. It's an AI agent for customer service. So, they are focused, laser-focused on the customer service application, and they want to do that better than anybody else in the world. In fact, if you measure by the metric of the number of resolutions, so when you have the agent resolve a customer service issue, that's resolution, they have a 59% average resolution rate, which makes it the highest-performing customer service agent on the market. It's uh trusted by over 5,000 customer service leaders, and even uh top AI companies including Anthropic. The way they design the system is uh it can continuously improve from the interactions, so you can uh continuously analyze, train, test, and deploy. Also, probably important to say, they uh give you a 90-day money-back guarantee. Go to fin.ai/lex to learn more about transforming your customer service and scaling your support team. That's fin.ai/lex. Shopify, a platform designed for anyone to sell anywhere with a great-looking online store. Even I figured out how to create an online store at lexfridman.com/store. I put up a few shirts. Haven't done anything with it since because I'm not a serious person. There's a lot of serious people that build real businesses on top of Shopify. It's a platform that connects you with millions of people that want to buy stuff and gives you all the tools you need and all the integrations that you need to do just that at scale. As we talked about with DHH about the incredible beauty and power of Ruby on Rails that Shopify is powered by. I have not yet build a serious sort of medium-scale project on Rails. I need to. It's just I need to actually find things that I need to do web dev type of stuff with to inspire myself to build something useful. I don't want to build some weird variant of a to-do list, especially now with the help of LLMs, you can generate so much of the code. So, I need to figure out how to learn new framework and new programming languages when LLMs can generate so much of it. And I don't want to do it exclusively by vibe coding because I feel like that's not a way to learn fully a thing, but vibe coding does remove some of the friction of learning. So, balancing that out is a tricky thing to do. Anyway, that's about the programming language and the framework that powers Shopify. But Shopify itself connects buyers and sellers in an incredible scale that's awe-inspiring. Sign up for a $1 per month trial period at shopify.com/lex. That's all lowercase. Go to shopify.com/lex to take your business to the next level today. Element, my daily zero sugar and delicious electrolyte mix. I've been traveling recently and I have a lot of Element packets with me and I bring that and I bring bands, uh you call them. I don't know what they're called. They're like rubber bands for like um basic shoulder exercises. So, if I have to do a lot of either heavy lifting or uh heavy jujitsu training, I like to warm up the shoulders really well cuz probably cuz I have issues with shoulders from many years of playing tennis and many years of doing stupidly bench press. Anyway, I think Element is a critical component of my workout routine. Hydrate before, rehydrate after, fully embrace the deliciousness of watermelon salt flavor. The flavor of champions, the one I recommend. It's been quite a while since I tried the others. They're all good, but for me, I'm a man of focus and dedication. >> [gasps] >> And I'm dedicated to watermelon salt. I think they have actually, uh I saw a lemonade flavor. I think a lot of people love lemonade. So, maybe that's your thing. For me, I'm sticking to watermelon salt. Get a free 8-count sample pack with any purchase. Try it to drinkelement.com/lex. This episode was also brought to you by AG1, an all-in-one daily drink to support better health and peak performance. I travel with it. It makes me feel like I take a little piece of home with me. I drink it at least once a day, very often twice a day. And they keep innovating, they keep improving it. They recently introduced uh AG1 next gen, improving every aspect, more vitamins and minerals, and upgraded probiotics. It's funny how a morning routine can be the source of peace and happiness. Cuz I uh I find that if I check my phone at all in the first couple hours of the day, I get this weird anxiety that ultimately morphs into unhappiness. And if I don't, I'm much more likely to sort of maintain that deep focus. And a part of that early in the morning is some coffee or caffeinated drink, and then a few hours on is AG1. And it's just many hours of deep focus in between. It makes me feel happy, makes me feel at one with the universe, and it helps me get done. Anyway, they'll give you a 1-month supply of fish oil when you sign up at drinkAG1.com/lex. This is a Lex Fridman podcast. To support it, please check out our sponsors in the description or at lexfridman.com/sponsors, and consider subscribing, commenting, and sharing the podcast with folks who might find it interesting. I promise to work extremely hard to always bring you nuanced and long-form conversations with a wide variety of interesting people from all walks of life. And now, dear friends, here's Demis Hassabis. >> [music] >> In your Nobel Prize lecture, you proposed what I think is a super interesting conjecture that, quote, any pattern that can be generated or found in nature can be efficiently discovered and modeled by a classical learning algorithm. What kind of patterns or systems might it be included in that? Biology, chemistry, physics, maybe cosmology, >> Yeah. >> neuroscience, what what are we talking about? >> Sure. Well, look, I felt that it's sort of a tradition, I think, of Nobel Prize lectures that you're supposed to be a little bit provocative, and I wanted to follow that tradition. What I was talking about there is if you take a step back and you look at all the work that we've done, especially with the Alpha X projects, so I'm thinking Alpha Go, of course, AlphaFold. What they really are is we're building models of very combinatorially high-dimensional spaces that, you know, if you try to brute-force a solution, find the best move in Go, or find the the exact shape of a protein, and if you enumerated all the possibilities, you there wouldn't be enough time in the in the you know the time of the universe. So, you have to do something much smarter. And what we did in both cases was build models of those environments. Um and that guided the search in a in a smart way. And that makes it tractable. So, if you think about protein folding, which is obviously a natural system, you know, why should that be possible? How does physics do that? You know, proteins fold in milliseconds in our bodies. So, somehow physics solved this problem that we've now also solved computationally. And I think the reason that's possible is that in nature, natural systems have structure because they were subject to evolutionary processes that that shaped them. And if that's true, then you can maybe learn uh uh what that structure is. >> So, this perspective, I think, is a really interesting one. You've hinted at at it, which is almost like uh crudely stated, anything that can be evolved can be efficiently modeled. Think there's some truth to that? >> Yeah, I sometimes call it survival of the stabilist or something like that because yeah it you know it's it's of course there's evolution for life, uh living things, but there's also, you know, if you think about geological time, so the shape of mountains, that's been shaped by weathering processes but over thousands of years. But then you can even take it cosmological, the orbits of planets, the um shapes of asteroids. These have all been survived kind of processes that have acted on them many many times. So, if that's true, then there should be some sort of pattern um that you can kind of reverse learn and uh a kind of manifold really that helps you uh search to the right solution, to the right shape, um and actually allow you to predict things about it uh in an efficient way. Because it's not a random pattern. Right? So, um it may not be possible for for man-made things or abstract things like factorizing large numbers because unless there's patterns in the number space, which there might be, but if there's not and it's uniform, then there's no pattern to learn. There's no model to learn that will help you search. So, you have to do brute force. So, in that case, you you know, you maybe need a quantum computer, something like this. But, in most things in nature that we're interested in are not like that. They have structure that evolved for a reason and survived over time. And if that's true, I think that's potentially learnable by a neural network. >> It's like nature's doing a search process. And it's so fascinating that it's in that search process it's creating systems that could be efficiently modeled. >> That's right. Yeah. >> So interesting. >> So, they can be efficiently rediscovered or recovered because nature's not random, right? These everything that we see around us, including like the elements that are more stable, all of those things, they're subject to some kind of selection process pressure. >> Do you think, because you're also a fan of theoretical computer science and complexity, do you think we can come up with a kind of complexity class, like a complexity zoo type of class, where maybe it's the set of learnable systems, the set of learnable natural systems, LNS? >> This is a Demis Hassabis new class of systems that could be actually learnable by classical systems in this kind of way, natural systems that can be modeled efficiently. >> Yeah. I mean, I've always been fascinated by the P equals NP question and what is modelable by classical systems, I non-quantum systems, you know, Turing machines in effect. And that's exactly what I'm working on actually in kind of my few moments of spare time with a few colleagues about is should there be, you know, maybe a new class of problem that is solvable by this type of neural network process and kind of mapped onto these natural systems. So, you know, the things that exist in physics and have structure. So, I think that could be a very interesting new way of thinking about it. And it sort of fits with the way I think about physics in general, which is that, you know, I think information is primary. Information is the most sort of fundamental unit of the universe, more fundamental than energy and matter. I think they can all be converted into each other, but I think of the universe as a kind of informational system. >> So, when you think of the the universe as an informational system, then the P equals NP question is a is a physics question. >> That's right. >> It is a question that can help us actually solve the entirety of this whole thing going on. >> Yeah, I think it's one of the most uh fundamental questions, actually, if you think of physics as informational. Uh and and the answer to that, I think, is going to be, you know, very enlightening. >> More specific to the P and NP question, this again, some of the stuff we're saying is kind of crazy right now, just like the Christian Anfinsen Nobel Prize speech controversial thing that he said sounded crazy, and then you went and got a Nobel Prize for this with John Jumper, solved the problem. So, let me let me just stick to the P equals NP. Do you think there's something in this thing we're talking about that could be shown if you get can do something like uh polynomial time or constant time compute ahead of time, and construct this gigantic model, then you can solve some of these extremely difficult problems in a theoretical computer science kind of way. >> Yeah, I think that there are I actually a huge class of problems that could be couched in this way, the way we did AlphaGo and the way we did AlphaFold, where, you know, you you model what the dynamics of the system is, the the the the properties of that system, the environment that you're trying to understand, and then that makes the search for the solution or the prediction of the next step efficient, basically polynomial time, so tractable by a uh classical system, uh which a neural network is. It runs on normal computers, right? Classical computers, uh Turing machines, in effect. And um I think it's one of the most interesting questions there is is how far can that paradigm go? You know, I think we've proven and the AI community in general that classical systems, Turing machines, can go a lot further than we previously thought. You know, they can do things like model the structures of proteins and play Go to better than world champion level. And you know, a lot of people would have thought maybe 10, 20 years ago that was decades away or maybe you would need some sort of quantum machines to to quantum systems to be able to do things like protein folding. And so, I think we haven't really even sort of scratched the surface yet of what classical systems, so-called, could do. And of course, AGI being built on a on a neural network system on top of a neural network system on top of a classical computer would be the ultimate expression of that. And I think the limit that you know, the the what what the bounds of that kind of system, what it can do, it's a very interesting question and and and directly speaks to the P equals NP question. >> What what do you think, again, hypothetical might be outside of this? Maybe emergent phenomena? Like if you look at cellular automata, some of the you have the extremely simple systems and then some complexity emerges. >> Yes. >> Maybe that would be outside or even would you guess even that might be amenable to efficient modeling by a classical machine? >> Yeah, I think those systems would be right on the boundary, right? So, I think most emergent systems, cellular automata, things like that, could be modelable by a classical system. You just sort of do a forward simulation of it and it probably be efficient enough. Of course, there's the question of things like chaotic systems where the initial conditions really matter and then you get to some, you know, uncorrelated end state. Now, those could be difficult to model. So, I think these are kind of the open questions, but I think when you step back and look at what we've done with the systems and the and the problems that we've solved, and then you look at things like VO3 on like video generation, sort of rendering, physics and lighting and things like that, you know, really core fundamental things in physics. Um it's pretty interesting. I think it's telling us something quite fundamental about how the universe is structured, in my opinion. Um so, you know, in in a way, that's what I want to build AGI for is to help uh us uh as scientists answer these questions uh like P equals NP. >> Yeah, [snorts] I think it will maybe continuously surprised about what is modelable by classical computers. I mean, AlphaFold 3 on the interaction side is surprising that you can make any kind of progress on that direction. Alpha genome is surprising that you can map the genetic code to the function. Kind of playing with the emergent kind of phenomena, you think there's so many combinatorial options that and then here you go. You can find the kernel that is efficiently modelable. >> Yes, because there there's some structure, there's some landscape, you know, in the energy landscape or whatever it is that you can follow, some gradient you can follow. And of course, what neural networks are very good at is following gradients. And so, if there's one to follow an object and you can specify the objective function correctly, you know, you don't have to deal with all that complexity, which I think is how we maybe have naively thought about it for decades, those problems. If you just enumerate all the possibilities, it looks totally intractable. And there's many, many problems like that. And then you think, well, it's like 10 to the 300 pop possible protein structures, uh it's 10 to the 170 possible go positions. All of these are way more than atoms in the universe. So, how could one possibly find the the right solution or predict the next step? And and it but it turns out that it is possible, and of course, reality and nature does do it. Right? Proteins do fold. So, that that gives you confidence that there must be if we understood how physics was doing that uh in a sense, uh then and we could mimic that process, i.e. model that process, uh it should be possible on our classical systems is is is basically what the conjecture's about. >> And of course there's non-linear dynamical systems, highly non-linear dynamical systems, everything involving fluid. >> Yes, right. >> I had a recent conversation with Terence Tao who mathematically uh it contends with a very difficult aspect of systems that have some singularities in them that break the mathematics. And it's just hard for us humans to make any kind of clean predictions about highly non-linear dynamical systems. But again, to your point, we may be very surprised what classical learning systems might be able to do about even >> Yes, exactly. I mean, fluid dynamics, Navier-Stokes equations, these are traditionally thought of as very very difficult, intractable kind of problems to do on classical systems. They take enormous amounts of compute, you know, weather prediction systems, you know, these kind of things all involve fluid dynamics calculations. And um but again, if you look at something like VEO, our video generation model, it can model liquids quite well, surprisingly well, and materials, specular lighting. I love the ones where, you know, there's there's people who generate videos where there's like clear liquids going through hydraulic presses and then it's being squeezed out. I I used to write uh physics engines and graphics engines in in my early days in gaming and I know it's just so painstakingly hard to build programs that can do that. And yet somehow these systems are, you know, reverse engineering from just watching YouTube videos. So, presumably what's happening is it's extracting some underlying structure around how these materials behave. So, perhaps there is some kind of lower dimensional manifold that can be learned if we actually fully understood what's going on under the hood. That's maybe, you know, maybe true of most of reality. >> Yeah, I've been continuously precisely by this aspect of VEO 3. I think a lot of people highlight different aspects including the comedic and the meaning and all that kind of stuff. >> And then the ultra-realistic ability to capture humans in a really nice way that's compelling and get feels close to reality and then combine that with native audio. All of those are marvelous things about VO3, but the exactly the thing you're mentioning, which is the physics. >> It's not perfect, but it's pretty damn good. And then the really interesting scientific question is what is it understanding about our world in order to be able to do that? Because if the cynical I take with the diffusion models there's no way it understands anything. But it seems I mean I don't think you can generate that kind of video without understanding and then our own philosophical notion of what it means to understand then is like brought to the surface. Like do to what degree do you think VO3 understands our world? >> I think to the extent that it can predict the next frames, you know, in a coherent way. That's some of that is a form, you know, of understanding, right? Not in the anthropomorphic version of you know, it's not the some kind of deep philosophical understanding of what's going on. I don't think these systems have that. But they they certainly have modeled enough of the dynamics, you know, put it that way, that they can pretty accurately generate whatever it is, 8 seconds of consistent video that by eye, at least you know, at a glance is quite hard to distinguish what the issues are. And imagine that in two or three more years time. That's the thing I'm thinking about and how incredible that would they would look given where we've come from, you know, the early versions of that one or two years ago. And so the rate of progress is incredible and I think I'm like you, it's like a lot of people love all of the the the the stand-up comedians and the the the actually captures a lot of human dynamics very well and and body language, but actually the thing I'm most impressed with and fascinated by is the physics behavior, the lighting and materials and liquids and it's pretty amazing that it can do that. And I think that shows it that it has some notion of at least intuitive physics, right? How things are supposed to work intuitively, maybe the way that a human child would understand physics, right? As opposed to a you know, a PhD student really being able to unpack all the equations. It's more of an intuitive physics understanding. >> Well, that intuitive physics understanding, that's the base layer. That's the thing people sometimes call like a common sense. Like it it really understands something. I think that really surprised a lot of people. It blows my mind that I just didn't think it would be possible to generate that level of realism without understanding. >> Mhm. >> You there's this notion that you can only understand the physical world by having an embodied AI system, a robot that interacts with that world. That's the only way to construct an understanding of that world. >> But VO3 is directly challenging that, it feels like. >> And it's very interesting, you know, even though if we if you would ask me 5 10 years ago, I would have said even though I was a master in all of this, I would have said, well, yeah, you probably need to understand intuitive physics, you know, like if I push this off the table, this glass, it will maybe shatter, you know, and the and the liquid will spill out, right? So, we know all of these things. But I thought that, you know, there's a lot of theories in neuroscience, it's called action and perception where, you know, you you need to act in the world to really truly perceive it in a deep way. And there was a lot of theories about you need embodied intelligence or robotics or something or maybe at least simulated action so that you would understand things like intuitive physics. But it seems like you can understand it through passive observation, which is pretty surprising to me. And and again, I think hints at something underlying about the nature of reality in in in my opinion, beyond just the you know, the cool videos that it generates. And and of course, there's next stages is maybe even making those videos interactive. So, uh, one can actually step into them and move around them. Um, which would be really mind-blowing, especially given my games background. So, you can imagine. Uh, and then and then I think you know, you're we're starting to get towards what I would call a world model, a model of how the world works, the mechanics of the world, the physics of the world, and the things in that world. And of course that's what you would need for a true AGI system. >> I have to talk to you about video games. So, you you were being a bit trolly. >> [laughter] >> I I think you're you're having more and more fun on Twitter on X, which is great to see. So, guy named Jimmy Apples tweeted, "Let me play a video game of my VO3 videos already. Uh, Google cooked so good playable world models when?" spelled w e n {question mark}. Uh, and then you quote tweeted that with, "Now, wouldn't that be something?" So, how how hard is it to build game worlds with AI? Maybe can you look out into the future uh, of video games, hm, 5 10 years out? What do you think that looks like? >> Well, games were my first love really, and doing AI for games was the first thing I did professionally in my teenage years, and and was the first major AI systems that I built. And, uh, I always want to I have I want to scratch that itch one day and come back to that. So, you know, and I will do, I think, and um, I think I sort of dream about, you know, what would I've done back in the '90s if I'd had access to the kind of AI systems we have today, and I think you could build absolutely mind-blowing games. Um, and I think the next stage is I always used to love making all the games I've made are open world games. So, they're games where there's a simulation, and then there's AI characters, and then the player, uh, interacts with that simulation, and the simulation adapts to the way the player plays. And I always thought they were the coolest games because, uh, so games like Theme Park that I worked on where everybody's game experience would be unique to them. Right? Because you're kind of co-creating the game. Right? We set up the parameters, we set up initial conditions, and then you as the player immersed in it, and then you are co-creating it with the with the simulation. But of course, it's very hard to program open world games. You know, you've got to be able to create content whichever direction the player goes in, and you want it to be compelling no matter what the player chooses. Um and so, it was always quite difficult to build things like cellular automata actually type of those kind of classical systems which created some emergent behavior. But they're always a little bit fragile, a little bit limited. Now we're maybe on the cusp in the next few years, 5-10 years, of having AI systems that can truly create around your imagination, can now sort of dynamically change the story, and story tell the narrative around and make it dramatic no matter what you end up choosing. So, it's like the ultimate choose your own adventure sort of game. And you know, I think maybe we're within reach if you think of a kind of interactive version of VO, and then wind that forward 5 to 10 years, and you know, imagine how good it's going to be. >> Yeah, so you said a lot of super interesting stuff there. So, one, the open world built into that is a deep personalization, the way you've described it. So, it's not just that it's open world, but you can open any door and there'll be something there. It's that the choice of which door you open in an unconstrained way defines the world you see. So, some games tried to do that, they give you choice, >> but it's really just an illusion of choice because you're only like like Stanley Parable is game I played. It's it's it's really there's a couple of doors and it really just takes you down a narrative. Stanley Parable is a great video game, I recommend people play, that kind of in a meta way mocks the illusion of choice and there's philosophical notions of free will and so on. But uh I do like one of my favorite games of Elder Scrolls is Daggerfall, I believe, that they really played with a like random generation of the dungeons. >> Of if you can step in and they give you this feeling of an open world. And there, you mentioned interactivity, you don't need to interact That That's a first step cuz you don't need to interact that much. You just When you open the door, whatever you see is randomly generated for you. >> And that's already an incredible experience cuz you might be the only person to ever see that. >> Yeah. Exactly. And And so, but what you'd like is a little bit better than just sort of a random generation, right? So, you'd like uh and and also better than a simple AB hard-coded choice, right? That's not really uh open world, right? Like as you say, it's just giving you the illusion of choice. What you want to be able to do is is potentially anything in that game environment. Um and I think the only way you can do that is to have uh generated systems, systems that uh will generate that on the fly. Of course, you can't create infinite amounts of game assets, right? It's expensive enough already how AAA games are made today. And that was obvious to to us back in the '90s when I was working on all these games. I think maybe Black & White uh was the game that I worked on early stages of that that had the still probably the best AI learning AI in it. It was an early reinforcement learning system that you, you know, you were you were looking after this mythical creature and growing it and nurturing it. And depending how you treated it, it would treat the villagers in that world in the same way. So, if you were mean to it, it would be mean. If you were good, it would be protective. And so, it was really a reflection of the way you played it. So, actually all of the uh I've been working on sort of simulations and AI uh through the medium of games at the beginning of my career. And And really the whole of what I do today is still a follow-on from uh those early more hard-coded ways of doing the AI to now, you know, fully general learning systems that that are trying to achieve the same thing. >> Yeah, it's been interesting, hilarious, and fun to watch you and Elon obviously itching to create games cuz you're both gamers. And one of the sad aspects of your incredible success in so many domains of science, like serious adult stuff. >> That you might not have time to really create a game. You might end up creating the tooling that others would create the game and you have to watch >> others create the thing you've always dreamed of. Do you think it's possible you can somehow in your extremely busy schedule actually find time to create something like black and white, some some an actual video game where like you could make the childhood dream >> come become >> Well, you know, there's two things ways to think about that is maybe that with vibe coding as it gets better, there's a possibility that I could, you know, one could do that actually in the in your spare time. So, I'm quite excited about that as a as that would be my project if if I got the time to do some vibe coding. Um I'm actually itching to do that. And then the other thing is, you know, maybe it's a sabbatical after AGI has been safely stewarded into the world and delivered into the world. You know, that and then working on my physics theory as we talked about at the beginning, those would be the two my my two post-AGI projects, let's call it that way. >> I would I would love to see which post-AGI would you choose, solving the problem that some of the smartest people in human history contended with, so P equals NP, >> or creating a cool video. >> Yeah. Well, they they might but in my world they'd be related because it would be an open world simulated game as realistic as possible. So, you know, what what is what is the universe? That's that's that's speaking to the same question, right? NP equals NP, I think all these things are related, at least in my mind. >> I mean, in a really serious way, so of video games sometimes are looked down upon. It's just this fun side activity. But especially as AI does more and more of the difficult boring tasks, something we in in modern world called work. You know, video games is the thing in which we may find meaning, in which we may find like what to do with our time. You could create incredibly rich meaningful experiences. Like that's what human life is. And then in video games you can create more sophisticated more diverse ways of living. >> Yeah. I think so. I mean, those of us who love games and I still do is is is um you know, it's almost can let your imagination run wild, right? Like I I used to love games um and working on games so much because it's the fusion, especially in the '90s and two early 2000s, the sort of golden era, maybe the '80s of of of game of the games industry. And it was all being discovered, new genres were being discovered. We weren't just making games, we felt we were we were creating a new entertainment medium that never existed before. Like especially with these open world games and simulation games where you were co-create, you as the player were co-creating the story. There's no other media uh entertainment media where you do that, where you as the audience actually co-create the the story. And of course now with multiplayer games as well it can be a very social activity and can explore all kinds of interesting worlds in that. But on the other hand, you know, it's very important to um also enjoy and experience uh the physical world. But the question is then, you know, I think we're going to have to color confront the question again of what is the fundamental nature of reality. Uh what is the going to be the difference between these increasingly realistic simulations and uh multiplayer ones and emergent um and what we do in the real world. >> Yeah, there's clearly a huge amount of value to experiencing the real world nature. There's also a huge amount of value in experiencing other humans directly in person, the way we're sitting here today. But, we need to really scientifically, rigorously answer the question why. >> And which aspect of that can be mapped into the virtual world? >> Exactly. >> And it's not it's not enough to say, "Yeah, you should go touch grass and hang out in nature." It's like, "Why exactly is that valuable?" >> Yes. And I guess that's maybe the thing that's been uh haunting me, obsessing me from the beginning of my career. You can If you think about all the different things I've done, that's they're all related in that way. This simulation, nature of reality, and what is the bounds of, you know, what can be >> Sorry for the ridiculous question, but so far, what is the greatest video game of all time? What's up there? What what makes >> favorite one of all time is Civilization. I I have to say. That that was the the the Civilization 1 and Civilization 2, my favorite games of all time. Um >> I can only assume you've avoided the most recent one because it would probably you would That would be your sabbatical. That would you would disappear. >> Yes, [laughter] exactly. They take a lot of time, these Civilization games. So, uh I've got to be careful with them. >> Fun question. You and Elon seem to be somehow solid gamers. Uh is there a connection between being great at gaming and and uh being great leaders of AI companies? >> I don't know. I It's an interesting one. I mean, uh we both love games and uh it's interesting he wrote games as well to start off with. It's probably especially in the era I grew up in where home computers were just became a thing, you know, in the late '80s and '90s, especially in the UK. I had a Spectrum and then an a Commodore Amiga 500, which was my my favorite computer ever. And that's where I learned all my programming. And of course, it's a very fun thing uh to program is to program games. So, I think it's a great way to learn programming. Probably still is. And um and then of course, I immediately took it in directions of AI and simulations, which so I mean was able to express my interest in in games and my sort of wider scientific interests all together. And then the final thing I think that's great about games is it fuses um artistic design, you know, art with the the the most cutting-edge programming. Um, so again in the '90s, all of the most interesting uh technical advances were happening in gaming, whether that was AI, graphics, physics engines, uh hardware, even GPUs of course were designed for gaming originally. Um, so everything that was pushing computing forward in the in the '90s was due to gaming. So interestingly, that was where the forefront of research was going on, and it was this incredible fusion with with art. Um, you know, graphics, but also music and just the whole new media of storytelling. And I love that. For me, it's this sort of multi-disciplinary kind of effort is again something I've enjoyed my whole my whole life. >> I have to ask you. I almost forgot about one of the many and I would say one of the most incredible things recently uh that somehow didn't yet get enough attention is AlphaGo Evolve. We talked about evolution a little bit, but it's the Google DeepMind system that evolves algorithms. >> Are these kinds of evolution-like techniques promising as a component of future super intelligence systems? So if people don't know, it's kind of um I don't know if it's fair to say it's LLM-guided evolution search. >> So the evolutionary algorithms are doing the search and LLMs are telling you where. >> Yes, exactly. So LLMs are kind of proposing some possible solutions and then you do you use evolutionary computing on top to to to find some novel part of the of the search space. So actually I think it's an example of very promising directions where you combine LLMs or foundation models with other computational techniques. Evolutionary methods is one, but you could also imagine Monte Carlo tree search. Basically, many types of search algorithms or reasoning algorithms sort of on top of or using the foundation models as a basis. So, I actually think there's quite a lot of interesting things to be discovered probably with these sort of hybrid systems, let's call them. >> But, not to romanticize evolution, I'm only human, but you you think there's some value in whatever that mechanism is? Cuz we already talked about natural systems. Do you think where there's a lot of low-hanging fruit of us understanding being being able to model being able to simulate evolution and then using that whatever we understand about that nature-inspired mechanism to to then do search better and better and better. >> Yes. So, if you think about again breaking down the sort of systems we've built to their really fundamental core, you've got like the model of the of the underlying dynamics of the system. And then if you want to discover something new, something novel that hasn't been seen before, then you need some kind of search process on top to take you to a novel region of the of the of the search space. And you can do that in a number of ways. Evolutionary computing is one. With AlphaGo, we just used Monte Carlo tree search, right? And that's what found move 37, the new kind of never seen before strategy in Go. And so, that's how you can go beyond potentially what is already known. So, the model can model everything that you currently know about, right? All the data that you currently have, but then how do you go beyond that? So, that starts to speak about the ideas of creativity. How can these systems create something new, find discover something new? Obviously, this is super relevant for scientific discovery or pushing science and medicine forward, which we want to do with these systems. And you can actually bolt on some uh, fairly simple search systems on top of these models and get you into a new region of space. Of course, you also have to, um, make sure that uh, you're not searching that space totally randomly, or it would be too big. So, you have to have some objective function that you're trying to optimize and hill climb towards and that guides that search. >> But, there's some mechanism of evolution that are interesting. Maybe in the space of programs, but then the space of programs is an extremely important space cuz you can probably generalize the the everything, you know, that. But, you know, for example, mutation. This is not just Monte Carlo tree search where it's like a search. You could every once in a while >> Combine things, yeah. >> combine things out there like sub like a components of a thing. >> So, then, you know, what evolution is really good at is not just the natural selection. It's combining things and building increasingly complex hierarchical systems. So, that component is super interesting, especially like with Alpha Evolve in the space of >> Yeah, exactly. So, there's a you can get a bit of an extra property out of evolutionary systems, which is some new emergent capability may come about. Right? Of course, like it happened with life. Interestingly, with naive, uh, sort of traditional evolution competing methods without LLMs and the modern AI, the problem with them they there was a they were very well studied in the '90s and and and and early 2000s and some promising results, but the problem was they could never work out how to evolve new properties. New emergent properties. You always had a sort of subset of the properties that you put into the system, but maybe if we combine them with these foundation models, perhaps we can overcome that limitation. Obviously, uh, natural evolution clearly did cuz it it did evolve new capabilities. Right? So, bacteria to where we are now. So, clearly that it must be possible with evolutionary systems to generate, uh, new patterns, going back to the first thing we talked about and uh new capabilities and emergent properties. And maybe we're on the cusp of discovering how to do that. >> Yeah, listen, uh AlphaFold is one of the coolest things I've ever seen. I've I've On my desk at home, you know, most of my time is spent behind a computer just programming. And next to the the three screens is a a skull of a Tiktaalik, which is one of the early organisms that crawled out of the water onto land. And I just kind of watch that little guy. >> It's like you whatever the competition mechanism of evolution is is quite incredible. Yeah, it's truly truly incredible. Now, whether that's exactly the thing we need to do to do our search, but never never dismiss the power of nature with what it did here. >> Yeah. And it's amazing. Um with with a relatively simple algorithm, right, effectively, and it can generate all of this immense complexity. It emerges. Obviously running over, you know, 4 billion years of time, but but it's it's it's you know, you can think about that as again a a process process that ran over the physics substrate of the universe for a long amount of computational time. But then it generated all this incredible rich diversity. >> So, so many questions I want to ask. So, one, you do have a dream. One of the natural systems you want to try to model is is a cell. That's a beautiful dream. Uh I could ask about that. I also just for that purpose on the AI scientist front just broadly. So, there's a essay from Daniel Kokotajlo, Scott Alexander, and others that outline steps along the way to get to ASI. And has a lot of interesting ideas in it. One of which is including a superhuman coder and a superhuman AI researcher. And in that there's a term of research taste That's really interesting. So, in everything you've seen, do you think it's possible for AI systems to have research taste? To help you in the way that AI co-scientist does to help steer human um human [clears throat] brilliant scientists and then potentially by itself to figure out what are the directions where you want to generate truly novel ideas? Cuz that seems to be like a really important of component how to do great science. >> Yeah, I think that's going to be one of the hardest things to to uh mimic or model is is this this idea of taste or or judgment. I think that's what separates the you know, the the great scientists from the good scientists. Like all all professional scientists are good technically, right? Otherwise, they wouldn't have been made it uh that far in in academia and things like that. But then, do you have the taste to sort of sniff out what the right direction is, what the right experiment is, what the right question is? So, the is the is the picking the right question is is the hardest part of science. Um and and making the right hypothesis. And um that's what you know, today's systems definitely they can't do. So, you know, I often say it's harder to come up with a conjecture, a really good conjecture, than it is to solve it. So, we may have systems soon that can solve pretty hard conjectures. Um you know, I I am in math olympiad problems. Well, we we you know, AlphaProof last year, our system got you know, silver medal in that. Really hard problems. Maybe eventually we'll be able to solve a millennium prize kind of problem. But could a system have come up with a conjecture worthy of study that someone like Terence Tao would have gone, you know what? That's a really deep question about the nature of maths or the nature of numbers or the nature of physics. And that is far harder type of creativity. And we don't really know today's systems clearly can't do that. And we're not quite sure what that mechanism would be. This kind of leap of imagination. Like like Einstein had when he came up with, you know, special relativity and then general relativity with the knowledge he had at the time. >> As for as for conjecture, the you want to come up with a thing that's interesting is amenable to proof. >> So like it's easy to come up with a thing that's extremely difficult. Yeah. It's easy to come up with a thing that's extremely easy, but that at that very edge >> That sweet spot, right? Of of basically advancing the science and splitting the hypothesis space into two ideally, right? Where the if it's true or not true, you you've learned something really useful. And um and and that's hard. And and and and making something that's also uh you know, falsifiable and within sort of the technologies that you have you currently have available. So it's a very creative process actually, highly creative process that um I I think just a kind of naive search on top of a model won't be enough for that. >> Okay, the idea of splitting the hypothesis space into super interesting. So uh I've heard you say that there's basically no failure in or failure is extremely valuable if it's done if you construct the questions right, if you construct the experiments right, if you design them right, that failure or success are both useful. So perhaps because it splits the hypothesis space into two, it's like a binary search. >> Yes. That's right. So when you do like, you know, real blue sky research, there's no such thing as failure really as long as you're picking experiments and hypotheses that that that that meaningfully split the hypothesis space. So, you know, and you learn something you can learn something kind of equally valuable from an experiment that doesn't work. That should tell you if you've designed the experiment well and your hypotheses are are interesting, it should tell you a lot about where to go next. And um and then it's you're effectively doing a search process um and using that information in in you know, very helpful ways. >> So to go to your dream >> [snorts] >> of uh modeling a cell, uh what are the big challenges that lay ahead for us to make that happen? We should maybe highlight that AlphaFold I mean, there's just so many leaps. >> So, AlphaFold solved, if it's fair to say, protein folding, and there's so many incredible things we could talk about there, including the open sourcing. Uh the everything you've released. AlphaFold 3 is doing protein RNA DNA interactions, >> which is super complicated and and fascinating that's amenable to modeling. AlphaGenome uh predicts uh how small genetic changes, like if we think about single mutations, how they link to actual uh function. So, um those are it seems like it's creeping along to a sophisticated to much more complicated uh things like a cell. But, a cell has a lot of really complicated components. >> Yeah. So, what I've tried to do throughout my career is I have these really grand dreams, and then I try to, as you've noticed, and then I try to break but I try to break them down any you know, it's easy to have a kind of a crazy ambitious dream, but the the trick is how do you break it down into manageable, achievable interim steps that are meaningful and useful in their own right. And so, virtual cell, which is what I call the project of modeling a cell, I've had this idea, you know, of wanting to do that for maybe more like 25 years. And I used to talk with Paul Nurse, who is a bit of a mentor of mine in biology. He runs the you know, founded the Crick Institute and and won the Nobel Prize in in 2001. Uh it it is is we've been talking about it since, you know, before the year you know, in the '90s. And um and I come used to come back to every 5 years. It's like, what would you need to model of the full internals of a cell so that you could do experiments on the virtual cell, and what those experiment, you know, in silico, and those predictions would be useful for you to save you a lot of time in the wet lab, right? That would be the dream. Maybe you could 100x speed up experiments by doing most of it in silico. The search in silico and then you do the validation step in the wet lab. That would be that's the that's the dream. And so, but maybe now finally so I was trying to build these components AlphaFold being one that that would allow you eventually to model the full interaction a full simulation of a cell. And I'd probably start with the yeast cell and partly that's what Paul Nurse studied because the yeast cell is like a full organism that's a single cell, right? So, it's the kind of simplest single cell organism. And so, it's not just a cell it's a full organism. And um and yeast is very well understood. And so, that would be a good candidate for a kind of full simulated model. Now, AlphaFold is the is the solution to the kind of static picture of what is a what does a protein look 3D structure of protein look like? A static picture of it, but we know that biology all the interesting things happen with the dynamics, the interactions. And that's what AlphaFold 3 is is the first step towards is modeling those interactions. So, first of all pairwise, you know, proteins with proteins, proteins with RNA and DNA. But then the next step after that would be modeling maybe a whole pathway, maybe like the TOR pathway that's involved in cancer or something like this. And then eventually you might be able to model, you know, a whole cell. >> Also, there's another complexity here that stuff in a cell happens at different time scales. Is that tricky? It's like the you know, protein folding is you know, super fast. >> Um I don't know all the biological mechanisms. >> But some of them take a long time. And so, is that that's a level So, the levels of interaction has a different temporal scale that you have to be able to model. >> So, that would be hard. So, you'd probably need several simulated systems that can interact at these different temporal dynamics. Or at least maybe it's like a hierarchical system. So, you can jump up and down the the different temporal stages. >> So, can you avoid I mean one of the challenges here is not avoid simulating. For example, the quantum mechanical aspects of any of this, right? You want to not over model. You could skip ahead to just model the really high-level things that get you a really good estimate of what's going to happen. >> you you go to make a decision when you're modeling any natural system, what is the cutoff level of the granularity that you're going to model it to that and then captures the dynamics that you're interested in. So, probably for a cell, I I would hope that would be the protein level. Uh and that one wouldn't have to go down to the atomic level. Um so, you know, of course, that's where AlphaFold stuck kicks in. So, that would be kind of the basis and then you'd build these um higher-level simulations that um take those as building blocks and then you get the emergent behavior. >> Apologies for the pothead questions ahead of time, but will do you think uh we'll be able to simulate a model the origin of life? So, being able to simulate the first from from non-living organisms, the the birth of a living organism. >> I think that's a one of the of course, one of the deepest and most fascinating questions. Um I love that area of biology, you know, uh there's people like there's a great book by Nick Lane, one of the top top experts in this area called the the 10 great inventions of of of evolution. I think it's fantastic and it also speaks to what the great filters might be, but you know, prior or are they ahead of us? I think I think they're most likely in the past if you read that book of how unlikely to go, you know, have any life at all and then single cell to multi-cell seems an unbelievably big jump that took like a billion years, I think, on Earth to do, right? So, shows you how hard it was. >> Bacteria were super happy for a very long time. >> time before they captured mitochondria somehow, right? I don't see why not why AI couldn't help with that. Some kind of simulation again, it's again, it's a bit of a search process through a combinatorial space. Here's like all the you know, the chemical soup that that you start with, the primordial soup that you know, maybe was on Earth near these hot vents. Here's some initial conditions. Can you generate something that looks like a cell? So perhaps that would be a next stage after the virtual cell project is well, how how could you something like that emerge from the chemical soup? >> Well, I would love it if there was a move 37 for the origin of life. >> I think that's one of the sort of great mysteries. I think ultimately what we will figure out is there a continuum. There's no such thing as a line between non-living and living. But if we can make that rigorous. >> That that the very thing from the big bang to today has been the same process. If we can break down that wall that we've constructed in our minds of the actual origin of from non-living to living and it's not a line that it's a continuum that connects physics and chemistry and biology. >> As there's no line. >> I mean, this is my whole reason why I worked on AI and H I'm my whole life because I think it can be the ultimate tool to help us answer these kind of questions. And I don't really understand why um you know, the average person doesn't think like worry about this stuff more. Like how [laughter] how how can we not have a good definition of life and not and not living and non-living and >> the nature of time and let alone consciousness and gravity and all these things. It's it's just and quantum mechanics weirdness. It's just to me it's I've always had this this sort of screaming at me in my face. And that's it's getting louder. You know, it's like how what is going on here? You know, in in and I mean that in the deepest sense. Like in the you know, the nature of reality which has to be the ultimate question. >> That would answer all of these things. It's sort of crazy if you think about it. We can stare each other and all these living things all the time. We can inspect it in microscopes and take it apart almost down to the atomic level and yet we still can't answer that clearly in a a way that question of how do you define living? It's kind of amazing. >> Yeah, living you can kind of talk your way out of thinking about but like consciousness like we have this very obviously subjective conscious experience like we're at the center of our own world and it it feels like something and then how how how are you not screaming >> Yeah. [laughter] >> at the mystery but all whatever. I mean but really humans have been contending with the mystery of the world around them uh for a long long There's a lot of mysteries like what's up with the sun and and the rain >> like what's that about and then like last year we had a lot of rain and this year we don't have rain like what did we do wrong? Humans have been asking that question for a long time. >> Exactly. So we're quite I guess we've we've developed a lot of mechanisms to cope with this these deep mysteries that we can't fully we can see but we can't fully understand and we have to have to just get on with daily life and and and we get we keep ourselves busy right? In a way do we keep ourselves distracted? >> I mean weather is one of the most important questions of human history. We still it's that's the go-to small talk direction of the weather. >> especially in England. >> And then it's which is you know, famously is an extremely difficult system to model and even that system the Google DeepMind has made progress >> Yes, we've we have we've created the the best weather prediction systems in the world and they're better than traditional fluid dynamics sort of systems that usually calculated on massive supercomputers takes days to calculate it we've managed to model a lot of the weather dynamics with neural network systems with our weather next system and again it's interesting that those kinds of dynamics can be modeled even though they're very complicated almost bordering on chaotic systems in some cases a lot of the interesting aspects of that can be modeled by these neural network systems including very recently we had you know, cyclone prediction of where, you know, parts of hurricanes might go. Of course, super useful, super important for the world. And and and it's super important to do that very timely and very quickly and as well as accurately. And uh I think it's very promising direction again of, you know, simulating and uh so they can run forward predictions and simulations of very complicated real-world systems. >> As you mentioned that uh I've got a chance in Texas to meet a community of folks called the storm chasers. >> And what's really incredible about them, I need to talk to them more, is they're extremely tech-savvy. Because what they have to do is they have to use models to predict where the storm is. >> So they're it's this >> it's this this beautiful mix of like crazy enough to like go into the eye of the storm and like in order to protect your life and predict where the extreme events are going to be, they have to have increasingly sophisticated models of of weather. >> Yeah, it's it's a a beautiful balance of like being in it as living organisms and the the cutting edge of science. So, they actually might be using uh DeepMind system. So, that's >> Yeah, they I would hopefully they are and I'd I'd love to join them on one of those chases. [laughter] They look amazing, right? To actually experience it one time. >> Exactly. And then also to experience the correct prediction where something will come and how it's going to evolve. It's incredible. >> You've estimated that we'll have AGI by 2030. so, there's interesting questions around that. How will we actually know that we got there? Uh and uh what may be the move, quote, move 37 of AGI. >> My estimate is sort of 50% chance by in the next 5 years. So, you know, by 2030, let's say. And uh so I think there's a good chance that that could happen. Part of it is what what is your definition of AGI? Of course, people are arguing about that now and and uh mine's quite a high bar and always has been of like can we match the cognitive functions that the brain has, Right, so we know our brains are pretty much general Turing machines, approximate, and of course we created incredible modern civilization with our minds. So, that should also speak to how general the brain is. And for us to know we have a true AGI, we would have to like make sure that it has all those capabilities. It isn't kind of a jagged intelligence where some things it's really good at, like today's systems, but other things it's really flawed at. And and that's what we currently have with today's systems. They're not consistent. So, you'd want that consistency of intelligence across the board. And then we have some missing, I think, capabilities. Like sort of the true invention capabilities and creativity that we were talking about earlier. So, you'd want to see those. How you test that? I think you just test it. One way to do it would be a kind of brute force test of tens of thousands of cognitive tasks that, you know, we know that humans can do. And maybe also make the system available to a few hundred of the world's top experts, the Terrence Taos of each each subject area, and see if they can find, you know, give them give them a month or two and see if they can find an obvious flaw in the system. And if they can't, then I think you're you're pretty, you know, pretty you can be pretty confident you we have a a fully general system. >> Maybe to push back a little bit. It seems like humans are really incredible as the the intelligence improves across all domains to take it for granted. Uh like you mentioned Terrence Tao, uh these brilliant experts, they might quickly, in a span of weeks, take for granted all the incredible things it can do and then focus in well, "Haha, right there." You know, I I consider myself a first of all human. >> Uh >> I identify as human. Um is it I you know, some people listen to me talk and they're like, "That guy's not good at talking. The stuttering, the you know >> So like even humans have obvious across domains limits. Even just outside of mathematics and physics and so on. It I I I wonder if it will take something like a move 37. So on the positive side versus like a barrage of 10,000 cognitive tasks where it would be one or two where it's like >> Holy This is personal. >> are exactly. So I think there's the sort of blanket testing to just make sure you've got the consistency. But I think there are the sort of lighthouse moments like the move 37 that I would be looking for. So one would be inventing a new conjecture or a new hypothesis about physics like Einstein did. So maybe you could even run the back test of that very rigorously. Like have a cutoff of knowledge cutoff of 1900 and then give the system everything that was you know that was written up to 1900 and then and then see if it could come up with special relativity and general relativity, right? Like Einstein did. That that would be an interesting test. Another one would be can it invent a game like Go? Not just come up with move 37 a new strategy, but can it invent a game that's as deep as aesthetically beautiful as elegant as Go? And those are the sorts of things I would be looking out for. And probably a system being able to do several of those things, right? As for it to be very general. Not just one domain. And so I think that would be the signs at least that I would be looking for that we've got a system that's AGI level. And then maybe to fill that out you would also check their consistency. You know, make sure there's no holes in that system either. >> Yeah, something like a new conjecture or scientific discovery. That would be a cool feeling. That would be amazing. So it's not not just helping us do that, but actually coming up with something brand new. >> And you would be in the room for that. And so it would be like probably two or three months before announcing it. >> And you would just be sitting there trying not to tweet. >> Something like that. Exactly. It's like what is this amazing new, you know, physics idea and then we would probably check it with world experts in that domain, right? And validate it and kind of go through its workings and it I guess it would be explaining its workings, too. Um yeah, be an amazing moment. >> Do you worry that we as humans, even expert humans like you, might miss it, might miss it? >> it may be pretty complicated. So, it could be the analogy I give there is I don't think it will be um totally mysterious to the to the best human scientists, but it may be a bit like, for example, in chess, if I was to talk to Garry Kasparov or Magnus Carlsen and play a game with them and they make a brilliant move, I might not be able to come up with that move, but they could explain why afterwards that move made sense. And we would be able to understand it to some degree, not to the level they do, but in you know, if they were good at explaining, which is actually part of intelligence, too, is being able to explain in a simple way that what you're thinking about, I think that that would be very possible for the best human scientists. >> But I wonder, maybe you can you can educate me on the side of Go, I wonder if there's moves from Magnus or Garry where they at first will dismiss it as a bad move. >> Yeah. Sure. It could be, but then afterwards they will figure out with their intuition that that this why this works and then and then and then empirically, the nice thing about games is one of the great things about games is you can it's it's a sort of scientific test. Does it do win the game or not win? And then um that tells you okay, that move in the end was good. That strategy was good. And then you can go back and analyze that and and and and explain even to yourself a little bit more why, explore around it. And that's how chess analysis and things like that work. So, perhaps that's why my brain works like that cuz I I've been doing that since I was four and you're train you know, train it's sort of hardcore training in that way. >> But even even now like when I generate code there is this kind of nuanced fascinating contention that's happening where I might at first identify as a set of generated code as incorrect in in some interesting nuanced ways. But then I'm always have to ask the question is there a deeper insight here that that I'm the one who's incorrect. And that's going to as the systems get more and more intelligent, you're going to have to contend with that. It's like what what what do you mean? Is this a bug or a feature what you just came up with? >> and they're going to be pretty complicated to do, but of course it will be you can imagine also AI systems that are producing that code or whatever that is and then human programmers looking at but also not unaided with the help of AI tools as well. So it's going to be kind of an interesting you know maybe different AI tools to the ones that the more kind of monitoring tools than the ones that generated it. >> So if we look at a AGI system sorry to bring it back up but Alpha evolve super cool. So Alpha evolve enables on the programming side something like recursive self-improvement potentially. Like what if we can imagine what that AGI system maybe not the first version but a few versions beyond that. What does that actually look like? Do you think it will be simple? You think it will be something like a self-improving program and a simple one? >> I mean potentially that's possible I would say. I'm not sure it's even desirable because that's a kind of like hard takeoff scenario. But but you these current systems like Alpha evolve they have you know human in the loop deciding on various things. They're separate hybrid systems that interact. One could imagine eventually doing that end-to-end. I don't see why that wouldn't be possible. But right now you know I think the systems are not good enough to do that in terms of coming up with the architecture of the code. Um and again, it's a little bit reconnected to this idea of coming up with a new conjectural hypothesis. How like they they're good if you give them very specific instructions about what you're trying to do. Um but if you give them a very vague high-level instruction, that wouldn't work currently. Like uh and I think that's related to this idea of like invent a game as good as Go, right? Imagine that was the prompt. That's that's pretty underspecified. And so, the current systems wouldn't know I think what to do with that, how to narrow that down to something tractable. And I think they're similar like look, just make a better version of yourself. That's too that's too unconstrained. But we've done it in you know in and as you know with AlphaFold like things like faster matrix multiplication. So, when you when you hone it down to very specific thing you want, um it's very good at incrementally improving that. But at the moment, these are more like incremental improvements, sort of small iterations. Whereas if you know if you wanted a big leap in uh understanding, you'd need a you need a much larger uh advance. >> Yeah, but it could also be sort of to push back against hard takeoff scenario. It could be just a sequence of incremental improvements like matrix multiplication. Like it has to sit there for days thinking how to incrementally improve a thing and that it does so recursively. As you do more and more improvement, it'll slow down. So, there'll be like a like the path AGI won't be like a it'll be a gradual improvement over >> if it was just incremental improvements, that's how it would look. So, the question is could it come up with a new leap like the Transformers architecture? Like could it have done that back in 2017 when you know we did it and Brain did it? And it's it's not clear that that these systems something like AlphaFold wouldn't be able to do make such a big leap. So, for sure these systems are good. We have systems I think that can do incremental hill climbing and that's a kind of bigger question about is that all that's needed from here or do we actually need one or two more uh uh big breakthroughs? >> And can the same kind of systems provide the breakthroughs also? So, maybe get a bunch of S curves. Like incremental improvement, but also every once in a while leaps. >> Yeah, I don't think anyone has systems that can have shown unequivocally those big leaps. That that that right? We have a lot of systems that do the hill climbing of the S curve that you're currently on. >> Yeah. And that would be the move 37 is a >> Yeah, I think it would be a leap uh something like that. >> Uh do you think the scaling laws are holding strong on the pre-training, post-training, test and compute? Uh do you uh on the flip side of that anticipate AI progress hitting a wall? >> We certainly feel there's a lot more room just in the scaling. So, um actually all steps pre-training, post-training, and inference time. So, uh there's sort of three scalings that are happening concurrently. Um and we again there it's about how innovative you can be. And we you know, we pride ourselves on having the broadest and um deepest research bench. Uh we have amazing you know, incredible uh researchers and uh people like Noam Shazeer who you know, came up with Transformers and and Dave Silver you know, who led the AlphaGo project and so on. And um it's it's it's that research base means that if some new new breakthrough is required like an AlphaGo or Transformers, uh I would back us to be the place that does that. So, I actually quite like it when the terrain gets harder, right? Because then it veers more from just engineering to to true research and you know, research or research plus engineering and that's our sweet spot. And I I think that's harder it's harder to invent things than to than to um you know, fast follow. And um so, you know, we don't know. I would say it's a it's kind of 50/50 whether new things are needed or whether the scaling the existing stuff is going to be enough. And so, in true kind of empirical fashion, we're pushing both of those as hard as possible. The new blue sky ideas, and you know, maybe about half our resources are on that, and then and then uh scaling to the max the the current the current capabilities. And um we're still seeing some, you know, fantastic progress on uh each different version of Gemini. >> That's interesting the way you put it in terms of the deep bench that if uh progress towards AGI is more than just scaling compute. So, the engineering side of the problem and is more on the scientific side where there's breakthroughs needed. Then you feel confident DeepMind as well, but Google DeepMind as well positioned to kick ass in that domain. >> Well, I mean, if you look at the history of the last decade or 15 years, um it's been I mean, you know, maybe I don't know, 80-90% of the breakthroughs that more that underpins modern AI field was from, you know, originally Google Brain, Google Research, and DeepMind. So, yeah, I would back that to continue, hopefully. [laughter] >> Uh so, on the data side, are you concerned about running out of high-quality data, especially high-quality human data? >> I'm not very worried about that, partly because I think there's enough data uh and it's been proven to get the systems to be pretty good. And this goes back to simulations again. If you Do you have enough data to make simulations or so that you can create more synthetic data that are from the right distribution. Obviously, that's the key. So, you need enough real-world data in order to be able to uh create those kinds of generator data generators. And um I think that we're at that step at the moment. >> Yeah, you've done a lot of incredible stuff in the side of science and >> Doing a lot with not so much data. >> I mean, it's still a lot of data, but I guess enough to get that going. >> Exactly. So, exactly. >> Uh how crucial is the scaling of compute to building AGI? This is a question that's an engineering question. It's a almost a geopolitical question because it also integrated into that is supply chains and energy, a thing that you care a lot about, which is potentially fusion. So, innovating on the side of energy also. Do you think we're going to keep scaling compute? >> I think so for several reasons. I think compute There's There's the amount of compute you have for training. How often it needs to be co-located. So, actually even like, you know, bandwidth constraints between data centers can affect that. So, it's it's it's There's additional constraints even there. And that that's important for training obviously the largest models you can. But there's also because now AI systems are in products and being used by billions of people around the world, you need a ton of influence compute now. Um and then on top of that, there's the thinking systems, the new paradigm of the last year that where they get smarter the longer amount of inference time you give them at test time. So, all of those things need a lot of compute. And I don't really see that slowing down. Um and as AI systems become better, they'll become more useful and there'll be more demand for them. So, both from the training side The training side actually is is only just one part of that. It may even become the smaller part of of what's needed in the overall compute that that's required. >> Yeah, that's one sort of almost meme-y kind of thing, which is like the success in the incredible aspects of VL3. There's uh people kind of make fun of like the more successful it becomes, the you know, the servers are sweating. >> Yes. [laughter] Can't have inference. Yeah, yeah, exactly. We did a little video of of us of the servers frying eggs and things. And um that's right. And And And we're going to have to figure out how to do that. Um there's a lot of interesting hardware innovations that we do. As you know, we have our TPU line. And we're looking at like inference-only things, inference-only chips, and how we can make those more efficient. We're also very interested in building AI systems, and we have done that help with energy usage. So, help um data center energy like for the cooling systems be efficient, um grid optimization, um and then eventually things like helping with uh plasma containment fusion reactors. We've done lots of work on that with Commonwealth Fusion, and also uh one could imagine reactor design, um and then material design I think is one of the most exciting. New types of solar material, solar panel material, super room temperature superconductors has always been on my list of dream breakthroughs, and um optimal batteries. And I think a solution to any, you know, one of those things would be absolutely revolutionary for, you know, climate and energy usage. And we're probably close, you know, and again in the next 5 years to having AI systems that can materially help with those problems. >> So, if you were to bet, sorry for the ridiculous question, but what what is the main source of energy uh in like 20, 30, years? Do you think it's going to be nuclear fusion? >> I think fusion and solar are the two that I I would bet on. Um solar, I mean, you know, it's the fusion reactor in the sky, of course. And I think really the the problem there is is is batteries and transmission. So, you know, as well as more efficient more more efficient solar material, perhaps eventually, you know, in space, you know, these kind of Dyson sphere type ideas. And fusion I think is definitely doable, seems, uh if we have the right design of reactor and we can control the plasma and uh fast enough and so on. And I think both of those things will actually get solved. So, we'll probably have at least those will probably be the two primary sources of renewable clean almost free or perhaps free energy. >> What a time to be alive. >> If I uh traveled into the future with you 100 years from now, how much would you be surprised if we've passed a type one Kardashev scale civilization? >> I would not be that surprised if there was a like a 100-year time scale from here. I mean, I think it's pretty clear if we crack the energy problems in one of the ways we've just discussed, fusion or or very efficient solar. then if energy is kind of free and renewable and clean, um then that solves a whole bunch of other problems. So, for example, the water access problem goes away because you can just use desalination. We have the technology, it's just too expensive. So, only, you know, uh fairly wealthy countries like Singapore and Israel and so on like actually use it. But But if it was uh cheap, then every then, you know, all countries that have a coast could. But also, you'd have unlimited rocket fuel. You could just separate seawater out into hydrogen and oxygen using energy, and that's rocket fuel. So, uh combined with, you know, Elon's amazing self-landing rockets, then it could be like you sort of like a bus service to to space. So, that opens up, you know, incredible new resources and domains. Uh asteroid mining, I think will become a thing and maximum human flourishing to the stars. Like, that's what I uh dream about as well as like Carl Sagan's sort of idea of bringing consciousness to the universe, waking up the universe. And I I think human civilization will do that in the full sense of time if we get AI right and uh and and and crack some of these problems with it. >> Yeah, I wonder what it would look like if you're just a tourist flying through space. You would probably notice Earth because if you solve the energy problem, you would see a lot of space rockets, probably. So, it would be like traffic here in London, [clears throat] but in space. >> Yes, [laughter] exactly. >> a lot of rockets. >> And then you would probably see floating in space some kind of source of energy like solar, >> Yep. >> potentially. So, Earth would just look more on the surface more um technological. And then then you would use the power of that energy then to preserve the natural >> Like the rainforest and all that kind of stuff. >> for the first time in in human history, we wouldn't be resource constrained. And I think that's could be amazing new era for humanity where it's not zero-sum. Right, I have this land, you don't have it. Or if we take, you know, if the tigers have their forest, then the the local villagers can't What are they going to use? I I I think that this will help a lot. No, it won't solve all the problems because there's still other human foibles that will will will still exist, but it will at least remove one, I think one of the big vectors, which is scarcity of resources, you know, including land and more materials and energy. And we know we should be as some of us call it like and others call it about this kind of radical abundance era where there's plenty of resources to go around. Of course, the next big question is making sure that that's fairly, you know, shared fairly and everyone in society benefits from that. >> So, there is something about human nature where I go, you know, it's It's like Borat, like my neighbor, like I would like you start trouble. We we we do start conflicts. And that's why games throughout, as I'm learning actually more and more, even in ancient history, serve the purpose of pushing people away from war, actually hot war. So, maybe we can figure out increasingly sophisticated video games that pulls they they give us that >> the scratch the itch of like conflict, whatever that is, but but us the human nature and then avoid the actual hot wars that would come with increasingly sophisticated technologies because we're now have long past the stage where the weapons we're able to create can actually just destroy all of human civilization. So, it's no longer >> Um >> that's no longer a great way to start with your neighbor. It's better to play a game of chess >> or football >> or football. Yeah. >> And I think I mean I think that's what my modern sport is. So and I love football, watching it and and I just feel like and I used to play it a lot as well and it's it's it's it's it's very visceral and it's tribal and I think it does channel a lot of those energies into a which I think is a kind of human need to belong to some some group and but into a into a into a fun way healthy way and and a not a not destructive way kind of constructive thing. And I think going back to games again is I think the originally why they're so great as well for kids to play things like chess is they're great little microcosm simulations of the world. They're they're simulations of the world too. They're simplified versions of some real world situation whether it's poker or or go or chess different aspects or diplomacy different aspects of of the real world and it allows you to practice at them too. And cuz you know how many times do you get to practice a massive decision moment in your life? You know what job to take what university to go to? You know you get maybe I don't know a dozen or so key decisions one has to make and you got to make those as best as you can. And games is a kind of safe environment repeatable environment where you can get better at your decision making process and it maybe has this additional benefit of channeling some energies into into more creative and constructive pursuits. >> Well, I think it's also really important to practice losing and winning. >> Right. >> Like losing is a really you know that's why I love games. That's why I love even things like Brazilian Jiu Jitsu where you can get your ass kicked in a safe environment over and over. It reminds you about the way about physics about the way the world works about the sometimes you lose sometimes you win. You can still be friends with everybody. But that that feeling of losing I mean it's a weird one for humans to like really like make sense of. Like that's just part of life. That is a fundamental part of life is losing. >> Yeah. And I think in martial arts as I understand it, but also in things like like chess is a lot at least the way I took it, it's a lot to do with self-improvement, self-knowledge, you know, that okay, so I did this thing. It's not about really being the other person. It's about maximizing your own potential. If you do it in a healthy way, you learn to use victory and losses in a way. Don't get carried away with victory and and think you're the just the best in the world. And and and the losses keep you humble. And always knowing there's always something more to learn. There's always a bigger expert that you can mentor you. You know, I think you learn that I I I'm pretty sure in martial arts. And and and I think that's also the way that at least I was trained in chess. And so in the same way and it can be very hardcore and very important. Of course, you want to win, but you also need to learn how to deal with setbacks in a in a healthy way that and and and and why are that that feeling that you have when you lose something into a constructive thing of next time, I'm going to improve this, right? Or get better at this. >> There is something that's a source of happiness, a source of meaning that improvement stuff. It's not about the winning or losing. >> Yes, the mastery. There's nothing more satisfying in a way is like, oh wow, this thing I couldn't do before, now I can. And and and again, games and physical sports and and mental sports, they're they're ways of measuring. They're beautiful because you can measure that that progress. >> Yeah. I mean, there's something about I guess why I love role-playing games. Like the number go up of like >> on the skill tree. Like literally, that is a source of meaning for us humans. Whatever our >> Yeah, we're quite we're quite addicted to this sort of yeah, these numbers going up. And and and and and maybe that's why we made games like that because obviously that is something we're we're we're hill climbing systems ourselves, right? >> Yeah, it it would be quite sad if we didn't have any mechanism to >> color belts. All the we do we do we do this everywhere, right? Where we just have this thing that >> It's in a I don't want to dismiss that. There is a source of deep meaning for us humans. Um so, one of the incredible stories on the business on the leadership side is um what Google has done over the past year. So, I uh I think it's fair to say that Google was losing on the LLM product side uh a year ago with Gemini 1.5. And now it's winning with Gemini 2.5. And you took the helm and you led this effort. What did it take to go from let's say {quote} "losing" to {quote} "winning" in the in in the span of a year? >> Yeah, well, firstly, it's absolutely incredible team that we have, you know, led by Corrado and Jeff Dean and and Oriol and the amazing team we have on Gemini. Absolutely world-class. So, you can't do it without the best talent. Um and of course, you have you know, we have a lot of great compute as well. But then, it's the research culture we created, right? And basically, coming together both different groups in in Google, you know, there was Google Brain, world-class team, and and then the old DeepMind. And pulling together all the best people and the best ideas and gathering around to make the absolute greatest system we could. And it has been hard, um but we're all very competitive. Uh and we, you know, love research. This is so fun to do. Um and we, you know, it's great to see our trajectory. It wasn't a given, but we're very pleased with um the the where we are and the rate of progress is the most important thing. So, if you look at where we've come to from 2 years ago to 1 year ago to now, you know, I think our we call it relentless progress along with relentless shipping of that progress is um being very successful. And you know, um it's unbelievably competitive uh the whole space, the whole AI space with some of the greatest entrepreneurs and leaders uh and companies in the world all competing now because everyone's realized how important AI is. Um and it's very, you know, been pleasing for us to see that progress. >> You know, Google's a gigantic company. Can you speak to the natural things that happen in that case is the bureaucracy that emerges? Like you want to be careful. Like you know, like that the natural kind of there's there's meetings and there's managers and that. Like what what are some of the challenges from a leadership perspective breaking through that in order to, like you said, ship? Like the the number of products >> Gemini related products that's been shipped over the past years is insane. >> Right. It is. Yeah, exactly. That's that's what relentlessness looks like. Um, I think it's it's a question of like any big company, you know, ends up having a lot of layers of management and things like that. It's sort of the nature of how it works. But I still operate and I was always operating with Old DeepMind as a as a startup still. Large one, but still as a startup. And that's what we still act like today in as with Google DeepMind. And acting with decisiveness and the energy that you get from the best smaller organizations. And we try to get the best of both worlds where we have this incredible billions of users surfaces incredible products that we can power up with our AI and our and our research. And that's amazing and you can, you know, there's very few places in the world you can get that. Do incredible world-class research on the one hand and then plug it in and and improve billions of people's lives the next day. That's a pretty amazing combination. And we're continually fighting and cutting away bureaucracy to allow the research culture and the relentless shipping culture to flourish. And I think we've got a pretty good balance whilst being responsible with it, you know, as you have to be as a large company and also with a number of, you know, huge product surfaces that we have. >> So funny thing you mentioned about like the the surface of the billion. I I had a conversation with a guy named, brilliant guy, here at the British Museum called Irving Finkel. He's a world expert at cuneiforms, which is a ancient writing on tablets. And he doesn't know about chat GPT or Gemini. He doesn't even know anything about AI. But his first encounter with this AI is AI mode on the >> Yes. Yes. >> He's like, is that what you're talking about this AI mode? >> And then, you know, it's just it's just a reminder that there's a large part of the world that doesn't know about this AI thing. >> Yeah. I know, it's funny cuz if you live on X and Twitter and I mean, it's sort of at least my feed, it's all AI and and there's certain places where, you know, in the valley and certain pockets where everyone's just all they're thinking about is AI. But a lot of the normal world hasn't hasn't come across it yet. >> And that's a great responsibility to their first interaction. >> On the the the grand scale of the rural India or anywhere across the world. You get to >> Right. And we want it to be as good as possible. And in a lot of cases, it's just under the hood powering making something like maps or search work better. And and it's ideally for a lot of those people should just be seamless. It's just new technology that makes their lives more, you know, productive and and and helps them. >> A bunch of folks on the Gemini product and engineering teams spoken extremely highly of you on another dimension that I almost didn't even expect cuz I kind of think of you as the like deep scientist and caring about these big research scientific questions. But they also said you're a great product guy. Like how to create a thing that a lot of people would use and enjoy using. So, can you maybe speak to what it takes to create a AI-based product that a lot of people would enjoy using? >> Yeah, well, I mean, again, that comes back from my game design days where I used to design games for millions of gamers. People forget about that. I've had experience with cutting-edge technology in product. That that that that is how games was in the '90s. And so, I love actually the combination of cutting edge research and then being applied in a product and to power a new experience. And so I think it's the same skill really of of you know imagining what it would be like to use it viscerally and having good taste coming back to earlier. The same thing that's useful in science I think is can also be useful in in product design and I've just had a very you know always been a sort of a multi-disciplinary person. So I don't see the boundaries really between you know arts and sciences or product and research. It's it's a continuum for me. I mean I only work on I like working on products that are cutting edge. I wouldn't be able to you know have cutting edge technology under the hood. I wouldn't be excited about them if they were just run of the mill products. So it requires this invention creativity capability. >> What are some specific things you kind of learned about when you even on the LLM side you're interacting with Gemini? You know like this doesn't feel like the layout the the interface maybe the trade off between the latency like how how to present to the user how long to wait >> and how that waiting is shown or the reason capabilities. There's some interesting things cuz it like you said it's the very cutting edge. We don't how to present it how to present it correctly. So is there some specific things you've you've learned? >> I mean it's such a fast evolving space where evaluating this all the time. But where we are today is that you want to continually simplify things the whether that's the interface or the interact what you build on top of the model. You kind of want to get out of the way of the model. The model train is coming down the track and it's improving unbelievably fast this relentless progress we talked about earlier. You know you look at 2.5 versus 1.5 and it's just a gigantic improvement and we expect that again for the future versions. And so the models are becoming more capable. So you've got the interesting thing about the design space in in in today's world, these AI first products, is you got to design not for what the thing can do today, the technology can do today, but in a year's time. So, you actually have to be a very technical product person because you got to kind of a good intuition for and feel for okay, that thing that I'm dreaming about now can't be done today, but is the research track on schedule to basically intercept that in 6 months or a year's time. So, you kind of got to intercept where this highly changing technology is going, as well as the new capabilities are coming online all the time that you didn't realize before that can allow like these research to work. Or now we got video generation, what do we do with that? This multimodal stuff, you know, is it one question I have is is it really going to be the current UI that we have today, these text box chats? Seems very unlikely given once you think about these super multimodal systems. Shouldn't it be something more like Minority Report where you're you're sort of vibing with it in a in a kind of collaborative way, right? It seems very restricted today. I think we'll look back on today's interfaces and products and systems as quite archaic in maybe in a just a couple of years. So, I think there's a lot of space actually for innovation to happen on the product side as well as the the research side. >> And then we were offline talking about this keyboard is the open question is how, when, and how much will we move to audio as the primary way of interacting with the machines around us versus typing stuff? >> Yeah, I mean typing is a very low bandwidth way of doing even if you're very fast, you know, typer. And I think we're going to have to start utilizing other devices, whether that's smart glasses, you know, audio earbuds, and eventually maybe some sort of neural devices where we can increase the the input and the output bandwidth to something, you know, maybe a 100X of what it is today. >> I think that, you know, under appreciated art form is the interface design. And I think you can not unlock the power of the intelligence of a system if you don't have the right interface. Their interface is really the way you unlock its power. It's such an interesting question of how to do that. So, how how it you would think like getting out of the way is an real art form. >> Yes. You know, it's the sort of thing that I guess Steve Jobs always talked about, right? It's simple simplicity, beauty, and elegance that we want, right? And we're not there nobody's there yet, in my opinion. And that's what I would like us to get to. Again, it sort of speaks to like Go again, right? As a game, the most elegant, beautiful game. Can you, you know, that can you make an interface as beautiful as that? And actually, I think we're going to enter an era of AI generated interfaces that are probably personalized to you, so it fits the way that you your aesthetic, your feel, the way that your brain works. And and and and the AI kind of generates that depending on the task, you know? That feels like that's probably the direction we'll end up in. >> Yeah, cuz some people are power users and they want every single parameter on screen, everything everything based like perhaps me with a keyboard keyboard-based navigation. I'd like to have shortcuts for everything. And some people like the minimalism. >> Just hide all of that complexity. Yeah, exactly. Well, I'm glad you have a Steve Jobs mode in you as well. This is great. Einstein mode, Steve Jobs mode. Um all right, let me try to trick you into answering a question. When when will Gemini 3 come out? Is it before after GTA 6? The world waits for both. And what does it take to go from 2.5 to 3.0? Because it seems like there's been a lot of releases of 2.5 which are already leaps in performance. So, what what does it even mean to go to a new version? Is it about performance? Is it about a complete different flavor of an experience? >> Yeah, well, so the way it works with our different version numbers is we you know, we try to collect so maybe it takes you know, roughly 6 months or something to to do a new kind of full run and the full productization of a new version and during that time lots of new interesting research iterations and ideas come up and we sort of collect them all together that you know, you could imagine the last 6 months worth of interesting ideas on the architecture front. Maybe it's on the data front. It's like many different possible things and we collect package that all up test which ones are likely to be useful for the next iteration and then bundle that all together and then we start the new you know, giant hero training run, right? And and then and then of course that gets monitored and then at the end then there's the of the pre-training then there's all the post-training. There's many different ways of doing that different ways of patching it. So there's a whole experimentation phase there which you can also get a lot of gains out and that's where you see the version numbers usually referring to the base model the pre-trained model and then the interim versions of 2.5 you know, and the different sizes and the different little additions. They're often patches or post-training ideas that can be done afterwards off the same basic architecture and then of course on top of that we also have different sizes Pro and flash and flashlight that are often distilled from the biggest ones you know, the flash model from the pro model and that means we have a range of different choices have you or the developer of do you want to prioritize performance or speed right and cost and we like to think of this Pareto Frontier well of you know, on the one hand the Y axis is you know, like performance and then the the the X axis is you know, cost or latency and and speed basically and we we have models that completely define the frontier. So whatever your trade-off is that you want as an individual user or as a as a developer, you should find one of our models satisfies that constraint. >> So, behind the version changes, there is a big hero run. >> And then there's uh just an insane complexity of productization. Then there's the distillation of the different sizes along that Pareto front. And then as each step you take, you realize there might be a cool product and the side quests. >> Yes, exactly. >> And then you also don't want to take too many side quests because then you have a million versions of million products. It's very unclear. But you also get super excited cuz it's super cool. Like how does even it look at VOs? Very cool. How does it fit into the bigger thing? >> exactly. Exactly. And then you're constantly this process of converging upstream, we call it, you know, ideas from the from the product surfaces or or or from the post training and and even further downstream than that, you you kind of upstream that into the the core model training for the next run. Right? So, then the main model, the main Gemini track, becomes more more general. And eventually, you know, AGI. >> One hero run at a time. >> Yes, exactly. Few hero runs later. Yeah. >> So, sometimes when you release these new versions or every version, really, are benchmarks productive or counterproductive for showing the performance of a model? >> You need them and and but it's important that you don't overfit to them. Right? So, they shouldn't be the end and the be-all and end-all. There's there's Eleuther AI Arena or it used to be called Eleuther AI LM-Eval-Harness, that's one of them that turned out sort of organically to be one of the the main ways people like to test these systems, at least the chatbots. Obviously, there's loads of academic benchmarks on from from that test mathematics and coding ability, general language ability, science ability, and so on. And then we have our own internal benchmarks that we care about. It's a kind of multi-objective you know, optimization problem. Right? You You don't want to be good at just one thing. We're trying to build general systems that are good across the board. And you try and make no regret improvements. So, where you improve in like, you know, coding, but it doesn't reduce your performance in other areas, right? So, that's the hard part cuz you you can Of course, you could put more coding data in or you could put more I don't know, gaming data in, but then does it make worse your language system or or uh in your translation systems and other things that you care about. So, it's you've got to kind of continually monitor this increasingly larger and larger suite of of benchmarks. And also there's uh when you stick them into products, these models, you also care about the direct usage and the direct stats and the signals that you're getting from the end users, whether they're coders or or or the average person using a using the chat interfaces. >> Yeah, because ultimately you want to measure the usefulness, but it's so hard to convert that into a number. >> It's It's really vibe-based benchmarks across a large number of users and it's hard to know. And I would it would be just terrifying to me to You know you have a much smarter model, but it's just something vibe-based. It's not not not quite working. That's just scary cuz and everything you just said, it has to be smart and useful across so many domains. So, you you get super excited cuz it's all of a sudden solving programming problems it's never been able to solve before, but now it's crappy at poetry or something. >> And it's just I don't know, that's a stressful. That's so difficult um >> To balance, yeah. >> to balance and because you can't really trust the benchmarks, you really have to trust the end users. >> Yeah. And then other things that are even more esoteric come into play like, um you know, the style of the persona of the the the system, you know, how it you know, is it verbose? Is it succinct? Is it humorous? You know, and it and different people like different things. um you know, it's very interesting. It's almost like cutting-edge part of psychology research or personal personality research. You know, I used to do that in my PhD like five-factor personality. What do we actually want our assistants to be like? And different people will like different things as well. So, these are all just sort of new problems in product space that I don't think have ever really been tackled before, but um we're going to sort of have rapidly have to deal with now. >> I think it's a super fascinating space developing the character of the thing. Yeah. And in so doing, it puts a mirror to ourselves what are the kind of things um that we like. Cuz prompt engineering allows you to control a lot of those elements, but can the product uh make it easier for you to uh control the different flavors of those experiences, the different characters that you interact with. >> Yeah, exactly. So, >> So, what's the probability of Google DeepMind winning? >> Well, I don't see it as sort of winning. I mean, I think we need to think winning is the wrong way to look at it given how important and consequential what it is we're building. So, funnily enough, I don't I try not to view it like a game or competition, even though that's a lot of my mindset. It's it's about in my view, all of us have those of us at the leading edge uh have a responsibility to um steward this unbelievable technology that could be used for incredible good, but also has risks. Um steward it safely into the world for the benefit of humanity. That's always um what I've um I dreamed about and what we've always tried to do, and I hope that's what eventually the community, maybe the international community will rally around when it becomes obvious that as we get closer and closer to to AGI that um that's what's needed. >> I agree with you. I think that's beautifully put. You've said that um you talk to and are on good terms with the leads of some of these uh labs. As the competition heats up, how hard is it to maintain sort of those relationships? >> It's been okay so far. I try to pride myself in being collaborative. I'm a collaborative person. Research is a collaborative endeavor. Science is a collaborative endeavor, right? It's all good for humanity in the end if you cure incredible, you know, terrible diseases and you come with an incredible cure. This is net win for humanity. And the same with energy, all of the things I'm interested in in in helping solve with AI. So, I just want that technology to exist in the world and be used for the right things. And and and the the kind of the benefits of that, the productivity benefits of that being shared for every the benefit of everyone. So, I try to maintain good relations with all the leading lab uh people. They've very interesting characters, many of them, as you might expect. Um but yeah, I'm on good terms, I I hope, with pretty much all of them and uh I I think that's going to be important when when things get even more serious than they are now. Uh that there are those communication channels and uh that's what will facilitate uh co- operation or collaboration if that's what was required, especially on things like safety. >> Yeah, I hope there's some collaboration on stuff that's uh sort of less high-stakes and in so doing serves as a mechanism for maintaining friendships and relationships. So, for example, I think the internet would love it if you and Elon somehow collaborate on creating a video game, that kind of thing. That I think that enables camaraderie and good terms. And also, you two are legit gamers, so it's just fun to >> fun to play some stuff. >> would be awesome. We've talked about that in the past and it may be a cool thing that that, you know, we can do. And I agree with you, it'd be nice to have um kind of side projects in a way where where we one can just lean into the collaboration aspect of it and it's a sort of uh win-win for both sides and it's um and it kind of builds up that that that uh collaborative muscle. >> I see the scientific endeavor as that kind of side project for humanity. And I I think Google DeepMind has been really pushing that. Uh I would love it if to see other labs do more scientific stuff and then collaborate cuz it just seems like easier to collaborate on the big scientific questions. >> I agree and I would love to see a lot of people A lot of the other labs talk about science, but I think we're really the only ones using it for science and doing that and that's why projects like AlphaFold are so important to me and I think to our mission is to show uh how AI can this you know be clearly used in a very concrete way for the benefit of humanity and and also we spun out companies like Isomorphic off the back of AlphaFold to do drug discovery and it's going really well and build sort of you know you can think of build additional AlphaFold type type systems to go into chemistry space to help accelerate drug design and the examples I think we need to show uh and society needs to understand of what AI can bring these huge benefits. >> Well, from the bottom of my heart thank you for pushing the scientific efforts forward with with rigor, with fun, with humility, all of that. I just love to see it and still talking about P equals NP. I mean it's just incredible. So I love it. Uh there are there there's been uh seemingly a war for talent. Some of it is meme. I don't know. Um what do you think about Meta buying up talent with huge salaries and and the heating up of this battle for talent. And I should say that I think a lot of people see DeepMind as a really great place to do uh cutting edge work for the reasons that you've outlined is like there's this vibrant scientific culture. >> Yeah, well look I I of course um you know there's a strategy that that Meta is taking right now. I think that um from my perspective at least I think the people that are real uh believers in the mission of AGI and what it can do and understand the real consequences both good and bad from that and what's what that responsibility entails. I think they're mostly doing it to be like myself to be on the frontier of that research. So you know they can help influence the way that goes and steward that technology safely into the world. And you know, Meta right now are not at the frontier, maybe they'll they'll manage to get back on there. And you know, it's probably rational what they're doing from their perspective because they're behind and they need to do something. But I think there's more important things than than just money. Of course, one has to pay, you know, people their market rates and all of these things, and that continues to go up. But as and and and I was expecting this because more and more people are finally realizing leaders of companies what I've always known for 30 plus years now, which is that AGI is the most important technology probably that's ever going to be invented. So in some senses it's it's rational to be doing that. But I also think there's a much bigger question. I mean, people in AI these days are very well paid. You know, I remember when we were starting out back in 2010, you know, I didn't even pay myself a couple of years cuz there was wasn't enough money. We couldn't raise any money. And these days interns are being paid, you know, the amount that we raised as our first entire seed round. So it's pretty funny. And I remember the days where we used I used to have to to work for free and and almost pay my own way to do an internship, right? Now it's all the other way around. But that's just how it is. It's the new world. And but I think that you know, we've been discussing that what happens post AGI and energy systems are solved and so on. What does even money going to mean? So I you know, in the economy and and we're going to have much bigger issues to work through and how does the economy function in that world and companies? So I think you know, it's a little bit of a side issue about salaries and things of like that today. >> Yeah, when you're facing such gigantic consequences and and gigantic fascinating scientific questions. >> Which may be only a few years away. So >> So on a practical sort of programmatic sense, if we zoom in on jobs, we can look at programmers because it seems like AI systems are currently doing incredibly well at programming and increasingly so. So a lot of people that uh, program for a living, and programming, are worried they will lose their jobs. How worried should they be, do you think? And what's the right way to uh, sort of adjust to the new reality and ensure that you survive and thrive as a human in the programming world? >> Well, it's interesting that programming, and it's again counterintuitive to what we thought years ago, maybe, that some of the skills that we think of as harder skills are turned out maybe to be the easier ones for various reasons, but you know, coding and math because you can create a lot of synthetic data and verify if that data's correct. So, because of that nature of that, it's easier to make things like synthetic data to train from. Um, it's also an area, of course, where we're all interested in, cuz we're as programmers, right, to help us and get faster at it and more productive. So, I think the for the next era, like the next 5-10 years, I think what we're going to find is people who are kind of embrace these technologies, become almost at one with them, um, whether that's in the creative industries or the technical industries, will become sort of super-humanly productive, I think. So, the great programmers will be even better, but they'll be even 10x even what they are today. And because they you'll be able to use their skills to utilize the the tools to the maximum, uh, you know, exploit them to the maximum. And, um, so I think that's what we're going to see in the next domain. Um, so that's going to cause quite a lot of change, right? And so, that's coming. A lot of people benefit from that. So, I think one example of that is if coding becomes easier, um, it becomes available to many more creatives to do more, uh, and, uh, but I think the top programmers will still have huge advantages as terms of specifying, going back to specifying what the architecture should be, the questions should be, how to guide these, um, coding assistants in a way that's useful, and, you know, check whether the code they produce is good. So, I think there's plenty of, um, uh, head room there for the foreseeable, you know, next few years. So, I think there's there's several interesting things there. One is there's a a lot of imperative to just get better and better consistently of using these tools so that you're riding the wave of the improvement improving models versus like competing against them. But sadly, but that's the the nature of of life on Earth. Um there could be a huge amount of value to certain kinds of programming at the cutting edge and less value to other kinds. For example, it could be like you know, front end web design might uh be more amenable to to to as as you mentioned to generation uh by AI systems and maybe for example, game engine design or something like this or back end designers or guiding systems in high-performance situations, high-performance programming type of design decisions that might be extremely valuable. But it will shift where the humans are needed most and that's scary for people to adjust. >> I think that's right. That that anytime where there's a lot of disruption and change, you know, we've had this is not just this time. We've had this in many times in human history with the internet, uh mobile, but before that was the Industrial Revolution. Um and it's going to be one of those eras where there will be a lot of change. I think there'll be new jobs we can't even imagine today just like the internet created and then those people with the right skill sets to ride that wave will become incredibly uh valuable. Right, those skills. But maybe people will have to relearn or adapt a bit uh their current skills. And it's the the thing that's going to be harder to deal with this time around is the I think what we're going to see is something like probably 10 times the impact the Industrial Revolution had and but 10 times faster as well. Right? So, instead of 100 years, it takes 10 years. And so, that's going to make it, you know, it's like a 100x uh the impact and the speed combined. So, that's what I think going to make it more difficult for society to to to deal with and it's good there's a lot to think through and I think we need to be discussing that right now and I I you know, encourage top economists in the world and philosophers to start thinking about um uh how should is society going to be affected by this and what should we do including things like um you know, universal basic provision or something like that where a lot of the um increased productivity uh get shared out and distributed uh to society um and maybe in the form of surface services and other things where if you want more than that, you still go and get some incredibly rare skills and things like that um and and make yourself unique um but uh but there's a basic provision that is provided. >> And if you think of government as a technology, there's also interesting questions not just in the economics but just politics. How do you design a system that's responding to the rapidly changing times such that you can represent the different pain that people feel from the different groups and how do you reallocate resources in a way that um addresses that pain and represents the hope and the pain and the fears of different people uh in a way that doesn't lead to division cuz uh politicians are often really good at sort of fueling the division and using that to get elected. The other mi defining the other and then saying that's bad and sort of based on that I think that's often counterproductive to leveraging a rapidly changing technology how to help the world flourish. So, we almost uh need to improve our political systems as well rapidly. If you think of them as a technology. >> Definitely and I think I think we'll need new governance structures, institutions probably to help with this transition. So, I think political philosophy and political science is going to be key to that. But, I think the number one thing first of all that is to create more abundance of resources, right? Then there's the So, that's the number one thing. Increase productivity, get more resources, maybe eventually get out of the zero-sum situation. Then the second question is how to use those resources and distribute those resources. But, yeah, you can't do that without having that abundance first. >> Uh you mentioned to me the book The Maniac by Benjamin Labatut, a book on uh first of all, about you. There's a bio about you. >> It's strange, yeah. >> It's unclear Yes, sir. >> It's unclear how much is fiction, how much is reality. Um but, I think the central figure that is John von Neumann. I would say it's a haunting and beautiful exploration of madness and genius and let's say the double-edged sword of discovery. And you know, for people don't know, John von Neumann is a kind of legendary mind. He contributed to quantum mechanics. He was on the Manhattan Project. He is widely considered to be the father of or pioneered the modern computer and AI and so on. So, as many people say, he's like one of the smartest humans ever. So, it's just fascinating. And what's also fascinating as as a person who saw nuclear science and physics become the atomic bomb. So, you you got to see ideas become a thing that has a huge amount of impact on the world. He also foresaw the same thing for computing. >> He's He And that's the a little bit again, beautiful and haunting aspect of the book. then taking a leap forward and looking at the at least at all AlphaZero AlphaGo AlphaZero big moment that maybe John von Neumann's thinking was brought to to to to reality. So, I I I guess the question is what do you think if you got to hang out with John von Neumann now? What what would he say about what's going on? >> Well, that would be an amazing experience. You know, he's a fantastic mind and and I also love the way he he spent a lot of his time at Princeton at the Institute of Advanced Studies, a very special place for thinking. And um it's amazing how much of a polymath he was and the the spread of things he helped invent, including of course the von Neumann architecture that all the modern computers are based on. And um he had amazing foresight. I think he would have loved where we are today and he would have um I think he would have really enjoyed AlphaGo being a you know, games that he also did game theory. I think he foresaw a lot of what would happen with learning machines, systems that that that are kind of grown, I think he called it rather than programmed. I'm not sure how even maybe he wouldn't even be that surprised. This the fruition of what I think he already foresaw in the 1950s. >> I wonder what advice he would give. He got to see the building of the atomic bomb with the Manhattan Project. I'm sure there's interesting stuff that maybe is not talked about enough, maybe some bureaucratic aspect, maybe the influence of politicians, maybe maybe not enough of picking up the phone and talking to people that are called enemies by the said politicians. There might be some like deep wisdom that we just may have lost from that time, actually. >> Yeah, I'm sure I'm sure there is. I mean, after we we you know, study I read a lot of books from that time as well, chronicle time and some brilliant people involved. I I agree with you. I think maybe there needs to be more dialogue and understanding. Um I hope we can learn from those those times. I think the difference here is that the AI has so many it's a multi-use technology. Obviously, we're trying to do things I like that like solve, you know, all diseases, help with energy and scarcity. These incredible things. This is why all of us and and myself, you know, I worked to start the on this journey 30 plus years ago. And um, but of course there are risks, too. And probably von Neumann, my guess is he foresaw both. And um, and I think he sort of said, I think it's to his wife that that that it would be a this is a computers will be even more impactful in the world. And as we just discussed, you know, I think that's right. I think it's going to be 10 times at least of the industrial revolution. So, I think he's right. So, I think he would have been, I imagine, fascinated by uh, where we are now. >> And I think one of the, maybe you can correct me, but one of the takeaways from the book is that reason, as uh, said in the book, Mad Dreams of Reason, is not enough for guiding humanity as we build these super powerful technology. That there's something else. I mean, that there's also like a religious component. Whatever God, whatever religion gives, it gives it pulls at something in the human spirit that raw, cold reason doesn't give us. >> And I I agree with that. I think we need to approach it with, whatever you want to call it, the a spiritual dimension or humanist dimension. It doesn't have to be to do with religion, right? But this idea of of a soul, what makes us human, the spark that we have, perhaps it's to do with consciousness when we finally understand that. Um, I think that has to be at the heart of the endeavor. Um, and technology, I've always seen technology as the enabler, right? The tools that that that enable us to to flourish and to understand more about the the world. And I'm sort of with Feynman on this, and he used to always talk about science and art being companions, right? You can understand it from both sides. The beauty of a flower, how beautiful it is, and also understand why the colors of the flower evolved like that, right? That just makes it more beautiful than than than just the intrinsic beauty of the flower. And and I've always sort of seen it like that. And maybe, you know, in the Renaissance times, the great discoverers then, like people like Da Vinci, you know, they were I don't think he saw any difference between science and art and perhaps religion, right? They were everything was it's just part of being human and being inspired about the world around us. And that's what I the philosophy I try to take and one of my favorite philosophers is Spinoza and I think he combined that all very well, you know, this idea of trying to understand the universe and understanding our place in it and that was his kind of way of understanding religion. And I think that's quite beautiful. And for me every all of these things are related, interrelated, the technology and what it means to be human. And I think it's a very important though that we remember that as when we're immersed in the technology and the the research. I think a lot of researchers that I see in in our field are a little bit too narrow and only understand the technology. And I think also that's why it's important for this to be debated by society at large and I'm very supportive of things like this the AI summits that will happen and governments understanding it. And I think that's one good thing about the chatbot era and the product era of AI is that everyday person can actually feel and and interact with cutting-edge AI and and and feel feel it for themselves. >> Yeah, because they they force the technologists to have the human conversation. Yeah, for sure. That's the hopeful aspect of it like you said it's a dual-use technology that we're forcefully integrating the entire humanity into it by into the discussion about AI because ultimately AGI will be used for things that states use technologies for, which is conflict and so on. And the more we integrate humans into this picture by having chats with them, the more it will guide >> Yeah, be able to adapt society will be able to adapt to these technologies. Like we've always done in the past with with the incredible technologies we've invented in the past. >> Do you think there will be something like a Manhattan Project where um there will be an escalation of the power of this technology and states in their old way of thinking will try to use it as weapons technologies and there will be this kind of escalation? >> I hope not. Um I think that would be uh very dangerous to do and I think also you know, not the right use of the technology. I I hope we'll end up with more something more collaborative if needed like more like a like a CERN project, you know, where um it's research-focused and the best minds in the world come together to carefully complete the final steps and make sure it's responsibly done before you know, like uh deploying it to the world. We'll see. I mean, it's difficult with the current geopolitical climate, I think, uh to to see cooperation, but things can change. And um I think at least on the scientific level, it's important for the researchers to to to to keep in touch and and and keep close to each other on at least on those kinds of topics. >> Yeah, that I personally believe on the education side and um immigration side, it would be great if both directions uh people from the West immigrated China and China back. I mean, there is some like family human aspect of people just intermixing. >> And thereby those ties grow strong so you can't sort of divide against each other this kind of old school way of thinking. And so multi uh multi cultural multi disciplinary research teams working on scientific questions, that's like the hope. Don't don't let the the warm leaders that are warmongers because they divide us. I think science is the ultimately really beautiful connector. >> Yeah, science has always been uh I think quite a a very collaborative endeavor and you know, scientists know that it's it's a it's a collective endeavor as well and we can all learn from each other. So, perhaps it could be a vector to get a bit of cooperation. >> What's your uh ridiculous question? What's your P doom? Probability the human civilization destroys itself? >> Well, look, I I don't have a >> it's a you know, I don't have a P doom number. The reason I don't is because I think it's would imply a level of precision that is not there. So, like I don't know how people are getting their P doom numbers. I think it's a kind of a little bit of a ridiculous notion because um what I would say is it's definitely non-zero, and it's probably non-negligible. So, that in itself is pretty sobering. And my my view is it's just hugely uncertain, right? What these technologies are going to be able to do, how fast are they going to take off, how controllable they're going to be. Some things may turn out to be, and hopefully, like way easier than we thought, right? Um but it may be there's some really hard um problems that are harder than we guess today. And I think uh we don't know that for sure. And so, in under those conditions of a lot of uncertainty, but huge stakes both ways, you know, on the one hand, we we could solve all diseases, energy problems, the not the the the the scarcity problem, and then travel to the stars and conquer the stars, and maximum human flourishing. On the other hand, is this sort of P doom scenarios. So, given the uncertainty around it and the importance of it, it's clear to me the only rational, sensible approach is to proceed with cautious optimism. So, we want the outcome we want the um uh the benefits, of course, uh and uh all of the the amazing things that AI can bring. And actually, I would be really worried for humanity if I if given the other challenges that we have, climate, disease, you know, aging, uh resources, all of that, if I didn't know something like AI was coming down the line, right? How would we solve all those other problems? I think it's hard. Um so, I think we've you know, it could be amazingly transformative for good. but on the other hand, you know, there are these risks that we know are there, but we can't quite quantify. So, the the best thing to do is to use the scientific method to do more research to try and uh more precisely define those risks and of course address them. Um and I think that's what we're doing. I think there probably needs to be uh 10 times more effort on that than there is now as we're getting closer and closer to the to the to the AGI line. >> What would be the source of worry for you more? Would it be human caused or AI AGI caused? Yeah, humans abusing the technology versus AGI itself through mechanism that you spoken about which is fascinating deception or this kind of stuff getting better and better and better secretly and then >> I think they they they operate over different time scales and they're equally important to address. So, there's just the the the the common gardenal variety of like, you know, bad actors using new technology uh in this case general purpose technology and repurposing it for harmful ends. And that's a huge uh risk. And I think that has a lot of complications because generally, you know, I'm in huge favor of open science and open source and in fact we did it with all our science projects like AlphaFold and all of those things uh for the benefit of of of the scientific community. Um but how does one restrict bad actors access to these powerful systems whether they're individuals or even rogue states uh and but enable access at the same time to good actors to to maximally build on top of. It's pretty tricky problem that there's I've not heard a clear solution to. So, there's the bad actor use case problem and then there's obviously uh as the systems become more agentic and and closer to AGI um and more autonomous, how do we ensure the guardrails and they stick to what we want them to do uh and under our control? >> Yeah, I tend to maybe on my mind is limited worry more about the humans the bad actors. And there it could be in part how do you not put destructive technology in the hands of bad actors, but in another part from again geopolitical technology perspective how do you reduce the number of bad actors in the world? That's that's also an interesting human problem. >> Yeah, it's a hard problem. I mean look we we we can maybe also use the technology itself to help early warning on some of the bad actor use cases, right? Whether that's bio or nuclear or whatever it is. Like AI could be potentially helpful there as long as the AI that you're using is itself reliable, right? So it's a sort of interlocking problem and that's what makes it very tricky and and again it may require some agreement internationally at least between China and the U and and the US of of of some basic standards, right? >> I have to ask you about the the book the maniac. There there's this the the hand of God moment Lisa Doll's move 78. That perhaps the last time a human did a move of sort of pure human genius and beat AlphaGo or like broke its brain if sorry to anthropomorphize, but it's an interesting moment cuz I think in so many domains it will keep happening. >> Yeah, it's a special moment and you know it was great for Lisa Doll and you know I think it's in a way they were sort of inspiring each other. We as a team were inspired by Lisa Doll's brilliance and nobleness and then maybe he got inspired by you know what AlphaGo was doing to then conjure this incredible inspirational moment. It's all you know captured very well in the in the documentary about it and I think that will continue in many domains where there's this at least for the for the again for the foreseeable future of like the humans bringing in their ingenuity um, and asking the right question, let's say, uh, and then utilizing these tools, uh, in a way that, um, then cracks a problem. >> Yeah, what as the AI becomes smarter and smarter, one of the interesting questions we can ask ourselves is what makes humans special. It does feel, um, perhaps biased that we humans are deeply special. I don't know if it's our intelligence. It could be something else, that that other thing that's outside the mad dreams of reason. >> I think that's what I've always imagined, uh, when I was a kid and starting on this journey of like, um, I was, of course, fascinated by things like consciousness, did did a neuroscience PhD to look at how the brain works, especially imagination and memory. I focused on the hippocampus. And it's sort of going to be interesting. I always thought the best way, of course, one can can philosophize about it and have thought experiments and maybe even do actual experiments like you do in neuroscience on on real brains. But in the end, I always imagined that building AI, a kind of intelligent artifact, and then comparing that to the human mind and seeing what the differences were, uh, would be the best way to uncover what's special about the human mind, if indeed there is anything special. And I suspect there probably is, but it's going to be hard to you know, I think this journey we're on will help us, uh, understand that and define that. And you know, there may be a difference between carbon-based substrates that we are and silicon ones when they process information. You know, one of the best definitions I like of of of consciousness is it's the way information feels when we process it, right? >> Um, it could be. I mean, it doesn't have it's not a very helpful scientific explanation, but I think it's kind of interesting intuitive one. And, um, and so, you know, on this this this journey, this scientific journey we're on will, I think, um, help uncover that mystery. >> Yeah, what I cannot create I do not understand. That's uh, somebody you deeply admire, Richard Feynman, like you mentioned. You also reach for the the Wigner's dreams of universality that he saw in constraint domains, but also broadly, generally in in mathematics and so on. So, so many aspects on which you're pushing towards not to start trouble at the end, but uh Roger Penrose. uh you know, do you do you think consciousness does this hard problem of consciousness, how information feels? do you think consciousness first of all is a computation? And if it is, if it's information processing, like you said, everything is, is it something that could be modeled by a classical computer? >> Or is it a quantum mechanical nature? >> Well, look, I Penrose is an amazing thinker, one of the greatest of the modern era, and he we've had a lot of discussions about this. Of course, we cordially disagree, which is, you know, I I I feel like um I mean, he collaborates with a lot of good neuroscientists to see if he could find mechanisms for quantum mechanics behavior in the brain, and they to my knowledge, they haven't found anything um convincing yet. So, my betting is there is is that that that it's mostly, you know, it is just classical computing that's going on in the brain, which suggests that all the phenomena uh are modelable or mimicable by uh classical computer. But, we'll see, you know, there there may be this final mysterious things of the feeling of consciousness, the qualia, these kinds of things that philosophers debate where it's unique to the substrate. We may even come towards understanding that when if we do things like neural link and and uh have neural interfaces to the AI systems, which I think we probably will eventually, um maybe to keep up with the AI systems, uh we might actually be able to feel for ourselves what it's like to compute on silicon, right? So, um and maybe that will tell us. Uh so, I think it's it's going to be interesting. And I had a debate once with the late Daniel Dennett about why do we think each other are conscious. Okay, so it's for two reasons. One is you're exhibiting the same behavior that I am. So, that's one thing. Behaviorally you seem like a conscious being if I am. But, the second thing which is often overlooked is that we're all running on the same substrate. So, if you're behaving in the same way and we're running on the same substrate, it's most parsimonious to assume you're feeling the same experience that I'm feeling. But, with a AI uh that's on silicon, we won't be able to rely on the second part. Even if it exhibits the first part, that behavior looks like a behavior of a conscious being. It might even claim it is. Um but, we but but we wouldn't know how it actually felt. Um and it probably couldn't know we what we felt. At least in the first stages, maybe when we get to superintelligence and the technologies that builds, perhaps we'll we'll be able to um bridge that. >> Yeah, I mean that's a huge test for radical empathy. It's to empathize with a different substrate. >> Exactly. We never had to confront that before. >> Yeah, to maybe maybe through brain-computer interfaces be able to truly empathize what it feels like to be a computer. >> Well, for information to be computed not on a carbon system. >> I mean that's deeply exciting. I mean, some people kind of think about that with plants, with other life forms, which is different. Similar substrate, but sufficiently far enough on the evolutionary tree that it's requires a radical empathy. But, to do that with a computer >> I mean, we sort of there are animal studies on this of like of course higher animals like, you know, killer whales and dolphins and dogs and and monkeys, you know, they have some and elephants, you know, they have some aspects certainly of consciousness, right? Even though they're not might not be that that that smart on an IQ sense. So, so we can already empathize with that and maybe even some of our systems one day like we built this thing called dolphin gemma, you know, which can one of our version of our system was trained on dolphin and whale sounds and maybe we'll be able to build a an interpreter or translator at some point. Should be pretty cool. >> What gives you hope for the future of human civilization? >> Well, what gives me hope is that I think our almost limitless ingenuity, first of all. I think the best of us and the best human minds are incredible. Um and you know, I love you know, meeting and watching any human that's the top of their game, whether that's sport or science or art. You know, it's it's it's just nothing more wonderful than that, seeing them in their element in flow. Um I think it's almost limitless. You know, our brains are general systems, intelligent systems. So, I I think it's almost limitless what we can potentially do with them. And then the other thing is our extreme adaptability. I think it's going to be okay in terms of there's going to be a lot of change, but that but look where we are now without effectively our hunter-gatherer brains. How is it we can, you know, we can cope with the modern world, right? Flying on planes, doing podcasts, you know, playing computer games in virtual simulations. I mean, it's already mind-blowing given that our mind was was developed for, you know, hunting buffaloes on the on the tundra. And and so, I think this is just the next step and and and it's actually kind of interesting to see how societies already adapted to this mind-blowing AI technology we have today already. It's sort of like, "Oh, I talk to chatbots. Totally fine." >> And it's very possible that this very podcast activity which I'm here for will be completely replaced by AI. >> I'm very replaceable and I'm waiting for it. >> that you can do it, Lex. I don't think. >> I thank you. That's >> That's what we humans do to each other. We compliment. All right. And I'm deeply grateful for us humans to have this infinite capacity for curiosity, adaptability, like you said, and also compassion and ability to love. >> All of those human things. >> things that are deeply human. >> Well, this is a huge honor, Demis. You're one of the truly special humans in the world. Thank you so much for doing what you do and for talking today. >> Well, thank you very much, Lex. >> Thanks for listening to this conversation with Demis Hassabis. To support this podcast, please check out our sponsors in the description and consider subscribing to this channel. And now, let me answer some questions and try to articulate some things I've been thinking about. If you'd like to submit questions, including in audio and video form, go to lexfridman.com/ama. I got a lot of amazing questions, thoughts, and requests from folks. I'll keep trying to pick some randomly and comment on it at the end of every episode. I got a note on May 21st this year that said, "Hi, Lex. 20 years ago today, David Foster Wallace delivered his famous This Is Water speech at uh Kenyon College. What do you think of this speech?" Well, first, I think this is probably one of the greatest and most unique commencement speeches ever given. But of course, I have many favorites, including the one by Steve Jobs. And David Foster Wallace is one of my favorite writers and one of my favorite humans. There's um tragic honesty to his work, and it always felt as if he was engaging in a constant battle with his own mind. And the writing, his writing, were kind of his notes from the front lines of that battle. Now, onto the speech. Let me quote some parts. There's of course the parable of the fish and the water that goes, "There are these two young fish swimming along and they happen to meet an older fish swimming the other way who nods at them and says, 'Morning, boys. How's the water?' And the two young fish swim on for a bit, and then eventually, one of them looks over at the other and goes, "What the hell is water?" In the speech, David Foster Wallace goes on to say, "The point of the fish story is merely that the most obvious, important realities are often the ones that are hardest to see and talk about." Stated as an English sentence, of course, this is just a banal platitude. But the fact is that in the day-to-day trenches of adult existence, banal platitudes can have a life or death importance. Or so I wish to suggest to you in this dry and lovely morning. I have several takeaways from this parable and the speech that follows. First, I think we must question everything, and in particular the most basic assumptions about our reality, our life, and the very nature of existence. And that this project is a deeply personal one. In some fundamental sense, nobody can really help you in this process of The call to action here, I think, from uh David Foster Wallace, as he puts it, is to quote, "To be just a little less arrogant. To have just a little more critical awareness about myself and my certainties." Because a huge percentage of the stuff that I tend to be automatically certain of is, it turns out, totally wrong and deluded. All right, back to me. Lex speaking. Second takeaway is that the central spiritual battles of our life are not fought on a mountaintop somewhere at a meditation retreat, but it is fought in the mundane moments of daily life. Third takeaway is that we too easily give away our time and attention to the multitude of distractions that the world feeds us. The insatiable black holes of attention. David Foster Wallace's call to action in this case is to be deeply aware of the beauty in each moment and to find meaning in the mundane. I often quote David Foster Wallace in his advice that the key to life is to be unborable. And I think this is exactly right. Every moment, every object, every experience when looked at closely enough contains within it infinite richness to explore. And since Demis Hassabis of this very podcast episode and I are such fans of Richard Feynman, allow me to also quote Mr. Feynman on this topic as well. Quote, I have a friend who's an artist and has sometimes taken a view which I don't agree with very well. He'll hold up a flower and say, "Look how beautiful it is." And I'll agree. Then he says, "I as an artist can see how beautiful this is, but you as a scientist take this all apart and it becomes a dull thing." And I think that's kind of nutty. First of all, the beauty that he sees is available to other people and to me too, I believe. Although I may not be quite as refined aesthetically as he is, I can appreciate the beauty of a flower. At the same time, I see much more about the flower than he sees. I can imagine the cells in there, the complicated actions inside which also have beauty. I mean, it's not just beauty at this dimension, at 1 cm. There's also beauty at the smaller dimensions. Their inner structure, also the processes. The fact that the colors in the flower evolved in order to attract insects to pollinate it is interesting. It means that the insects can see the color. It adds the question, does this aesthetic sense also exist in lower forms? Why is it aesthetic? All kinds of interesting questions which the science knowledge only adds to the excitement, the mystery, and the awe of a flower. It only adds. All right, back to David Foster Wallace's speech. He has a great story in there that I particularly enjoy. It goes, there are these two guys sitting together in a bar in the remote Alaskan wilderness. One of the guys is religious, the other is an atheist. And the two are arguing about the existence of God with that special intensity that comes after about the fourth beer. And the atheist says, "Look, it's not like I don't have actual reasons for not believing in God. It's not like I haven't ever experimented with the whole God and prayer thing. Just last month I got caught away from the camp in that terrible blizzard. And I was totally lost, and I couldn't see a thing, and it was 50 below. So, I tried it. I fell to my knees in the snow and cried out, 'Oh God, if there is a God, I'm lost in this blizzard and I'm going to die if you don't help me.'" And now back in the bar, the religious guy looks at the atheist all puzzled. "Well, then you must believe now," he says. "After all, there you are, alive." The atheist just rolls his eyes. "No, man. All that happened was a couple of Eskimos happened to be wondering by and showed me the way back to the camp." All this I think teaches us that everything is a matter of perspective, and that wisdom may arrive if we have the humility to keep shifting and expanding our perspective on the world. Thank you for allowing me to talk a bit about David Foster Wallace. He's one of my favorite writers and he's a beautiful soul. If I may, one more thing I wanted to briefly comment on. I found myself to be in this strange position of getting attacked online often from all sides, including being lied about, sometimes through selective misrepresentation, but often through downright lies. I don't know how else to put it. This all breaks my heart, frankly. But, I've come to understand that it's the way of the internet and the cost of the path I've chosen. There's been days when it's been rough on me mentally. It's not fun being lied about, especially when it's about things that are usually for a long time have been a source of happiness and joy for me. But again, that's life. I'll continue exploring the world of people and ideas with empathy and rigor, wearing my heart on my sleeve as much as I can. For me, that's the only way to live. Anyway, a common attack on me is about my time at MIT and Drexel, two great universities I love and have tremendous respect for. Since a bunch of lies have accumulated online about me on these topics to a sad and at times hilarious degree, I thought I would once more state the obvious facts about my bio for the small number of you who may care. TLDR, two things. First, as I say often, including in a recent podcast episode that somehow was listened to by many millions of people, I proudly went to Drexel University for my bachelor's, master's, and doctorate degrees. Second, I am a research scientist at MIT and have been there in a paid research position for the last 10 years. Allow me to elaborate a bit more on these two things now, but please skip if this is not at all interesting. So, like I said, a common attack on me is that I have no real affiliation with MIT. The accusation, I guess, is that I'm falsely claiming an MIT affiliation because I taught a lecture there once. Nope. That accusation against me is a complete lie. I have been at MIT for over 10 years in a paid research position from 2015 to today. To be extra clear, I'm a research scientist at MIT working in LIDS, the Laboratory for Information and Decision Systems in the College of Computing. For now, since I'm still at MIT, you can uh see me in the directory and on the various lab pages. I have indeed given many lectures at MIT over the years, a small fraction of which I posted online. Teaching for me always has been just for fun and not part of my research work. I personally think I suck at it, but I have always learned and grown from the experience. It's like Feynman spoke about, if you want to understand something deeply, it's good to try to teach it. But, like I said, my main focus has always been on research. I published many peer-reviewed papers that you can see in my Google Scholar profile. For my first 4 years at MIT, I worked extremely intensively. Most weeks were After that, in 2019, I still kept my research scientist position, but I split my time taking a leave to pursue projects in AI and robotics outside MIT and to dedicate a lot of focus to the As I've said, I've been continuously surprised just how many hours preparing for an episode takes. There are many episodes of the podcast for which I have to read, write, and think for 100, 200, or more hours across multiple weeks and months. Since 2020, I have not actively published research papers. Just like the podcast, I think it's something that's a serious full-time effort. But, not publishing and doing full-time research has been eating at me because I love research and I love programming and building systems that test out interesting technical ideas, especially in the context of human AI or human-robot interaction. I hope to change this in the coming months and years. What I've come to realize about myself is if I don't publish or if I don't launch systems that people use, I definitely feel like a piece of me is missing. It legitimately is a source of happiness Anyway, I'm proud of my time at MIT. I was and am constantly surrounded by people much smarter than me, many of whom have become lifelong colleagues and friends. MIT is a place I go to escape the world, to focus on exploring fascinating questions at the cutting edge of science and engineering. This again makes me truly happy. And it does hit pretty hard on a psychological level when I'm getting attacked over this. Perhaps I'm doing something wrong. If I am, I will try to do better. In all this discussion of academic work, I hope you know that I don't ever mean to say that I'm an expert at anything. In the podcast and in my private life, I don't claim to be smart. In fact, I often call myself an idiot and mean it. I try to make fun of myself as much as possible and in general to celebrate others instead. Now, to talk about Drexel University, which I also love, am proud of, and am deeply grateful for my time there. As I said, I went to Drexel for my bachelor's, master's, and doctor degrees in computer science and electrical engineering. I've talked about Drexel many times, including, as I mentioned, at the end of a recent podcast, the Donald Trump episode, funny enough, that was listened to by many millions of people, where I answered a question about graduate school and explained my own journey at Drexel and how grateful I am for it. If it's at all interesting to you, please go listen to the end of that episode or watch the related clip. At Drexel, I met and worked with many brilliant researchers and mentors from whom I've learned a lot about engineering, science, and life. There are many valuable things I gained from my time at Drexel. First, I took a large number of very difficult math and theoretical computer science courses. They taught me how to think deeply and rigorously and also how to work hard and not give up even if it feels like I'm too dumb to find a solution to a technical problem. Second, I programmed a lot during that time, mostly C, C++. I programmed robots, optimization algorithms, computer vision systems, wireless network protocols, multimodal machine learning systems, and all kinds of simulations of physical systems. This is where I really developed a love for programming, including, yes, Emacs and the Kinesis keyboard. Uh I also during that time read a lot. I played a lot of guitar, wrote a lot of crappy poetry, and uh trained a lot of uh in Judo and Jiu-Jitsu, which I cannot sing enough praises to. Jiu-Jitsu humbled me on a daily basis throughout my 20s, and it still does to this very day whenever I get a chance to train. Anyway, I hope that the folks who occasionally get swept up in the chanting online crowds that want to tear down others don't lose themselves in it too much. In the end, I still think there's more good than bad in people. But, we're all, each of us, a mixed bag. I know I am very much flawed. I speak awkwardly. I sometimes say stupid I can get irrationally emotional. I can be too much of a dick when I should be kind. I can lose myself in a biased rabbit hole before I wake up to the bigger, more accurate picture of reality. I'm human, and so are you, for better or for worse. And I do still believe we're in this whole beautiful mess together. I love you all. [music]
