Yes your message is clear.

To answer your original question, I have no idea what it will look like when software writes and reviews itself. It seems obvious that human understanding of a code base will quickly disappear if this is the process, and at a certain point it will go beyond the capacity of human refactoring.

My first thought is that a code base will eventually become incoherent and irredeemably buggy. But somebody (probably not an AI, at first) will teach ChatGPT to refactor coherently.

But the concept of coherence here becomes a major philosophical problem, and it's very difficult to imagine how to make it practical in the long run.

I think for now the practical necessity is to put extra emphasis on human peer review and refactoring. I personally haven't used AI to write code yet.

My dark side would love to see some greedy corporations wrecking their codebase by over-relying on AI to replace their coders. And debugging becomes a nightmare because nobody wrote it and they have to spend more time bug-fixing than they would have spent writing it in the first place.
