So far the issue for me is that you can generate more crap by far than you can keep an eye on.
Once you have your 50k line program that does X are you really going to go in there and deeply review everything? I think you're going to end up taking more and more on trust until the point where you're hostage to the AI.
I think this is what happens to managers of course - becoming hostage to developers - but which is worse? I'm not sure.
