Meh, disagree with a lot of this.

AI tools can generate functional, adequate, perfectly average code

Not in my experience.

The outsourcing era taught us that the expensive part of software was never writing it. It was understanding it well enough to change it safely, to debug it under pressure, to explain to the next person why a particular decision was made at 2 a.m. on a Tuesday.

Since AI is adequate, just have AI change, debug, and explain it. You don't even need devs running the AI. Have AI generate intent. Just have AI scrape Twitter for people complaining about applications they wish existed, and have the AI make them. Let AI do market research. It's supposedly perfectly adequate.
