On Sunday, Andrej Karpathy posted some napkin math about how differently people now experience AI. By his estimate, roughly 75% of the world's population has barely come in contact with these models at all. Another 20% or so treat free chatbots "a bit like a better Google search" or a writing aid. And then there is a thin sliver, professionals using frontier models for math and code: "Somewhere around 20M people (0.2%) see first-hand that large, complex projects that used to take them weeks/months can now be completed by agents with a prompt."
If you happen to be in that 0.2%, or even visiting it as a tourist, you know how addictive this feels. A friend of mine who is a musician by trade has been building an application with Claude Code that would put some developers to shame.
Yet every time I watch a demo like that, the same thought stays with me: the build was the easy half. When building gets cheap, the hard part does not disappear. It moves.
This week's piece is about where it moves: understanding the work you're building for, the user interface, and change management.

What was the hardest part of your last AI project, once the build was done?
Or, what a very good Claude Code or Codex prototype still has not proven
