I work with a large number of programmers who don't use AI and don't have an accurate mental map for the codebases they work in...

I don't think AI will make these folks more destructive. If anything, it will improve their contributions because AI will be better at understanding the codebase than them.

Good programmers will use AI like a tool. Bad programmers will use AI in lieu of understanding what's going on. It's a win in both cases.
