Wisdom is learning the lessons we thought we already knew. DeepSeek reminds us of three important learnings from computing history: 1) Computing obeys the gas law. Making it dramatically cheaper will expand the market for it. The markets are getting it wrong, this will make AI much more broadly deployed. 2) Engineering is about constraints. The Chinese engineers had limited resources, and they had to find creative solutions. 3) Open Wins. DeepSeek will help reset the increasingly closed world of foundational AI model work. Thank you DeepSeek team.
