Karpathy says AI coding is about knowing when to delete the worktree and say no

Andrej Karpathy argues that in AI-assisted coding, the hard skill is often knowing when to say no.
He describes spending a day building an architecture with an AI, then choosing to delete the worktree and start over. His point is that AI will happily produce more code and more refactors, but good taste and focus matter more than saying yes to everything.
