I think almost anything you can build autonomously with a fully independent AI agent, you can build far better with the slow AI approach. It is a good trade off between the super fast agentic approach and the full manual approach, and leaves you with a codebase you can still reason about and find ways to improve.

Also, once you build something with slow AI, it becomes more practical to actually rewrite it by hand quickly and refactor it in a way that makes more sense for humans. It’s “humanwashing” the code.
