DHH: Future of Programming, AI, Agentic Engineering, Vibe Coding & Linux | Lex Fridman Podcast #501
Thirteen months after his last appearance, DHH tells Lex Fridman he has not hand written a single line of the code that shipped in Omarchy Quattro, and spends five hours producing the receipts. He dates the turn to November 24th 2025 and Opus 4.5, argues the value of beautiful code is now conditional on token scarcity, merged over a thousand agent written pull requests in three months without reviewing them himself, and ranks six models on one real Python to Rust translation with times and token costs. It also runs through Rails, the 37signals model, racing, fatherhood, Danish immigration statistics, longevity, and why he would pick the 1980s.
