This is my ultimate (short term) AI fear - letting it get into a feedback loop with itself, leading to perverse and incorrect results.

To state my position more clearly: I don’t think an AI could comment code from scratch very well - how would it know all the decisions made, business logic considerations, historical conventions, micro-industry standards, etc?

A good benchmark I was told once was “if a human expert couldn’t do it, an AI probably can’t either”. And commenting code I didn’t write would certainly test the bounds of my abilities
