What parts of The Lean Startup would you update for the AI era?

none of them, really. Watch this video about the development of Claude Code and tell me if it sounds familiar: https://www.linkedin.com/feed/update/urn:li:activity:7470133...

Of course, many of the tactics and examples in the book are now a bit dated, so if I did an "AI edition" I guess we would update it with new stories and new tips on how to use various AI-powered tools to accelerate. But I think the principles have stood up pretty well.
