How To Build The Future: Sam Altman

From Y Combinator · Published Jul 20, 2025 · Watch on YouTube

TL;DR

Sam Altman argues that the current AI platform shift makes it the best time yet to start a technology company, driven by compounding progress in deep learning and scaling. OpenAI succeeded by concentrating on one bet (scaling neural networks) with extreme conviction, despite widespread skepticism.

Key insights

  • Deep learning works and improves predictably with scale; this belief was heretical when OpenAI started, and many field leaders considered it irresponsible.
  • Extreme conviction on a single bet (rather than spreading resources) is undervalued and can be a decisive advantage for startups, especially during platform shifts.
  • The world is still asleep on the current AI revolution, giving startups a window to move fast without established competition.
