> One thing that worries me about AI-generated code is that if there's an obscure bug that pops up later, there's no engineer to think "ok hang on, I remember something strange happening when I first wrote that code... let me have a look." Instead, there are only engineers who reviewed the code, which is of course a lot different from writing it.

I feel this is a very weak argument against AI. Professional software development rarely values crafting good code. You get it in to meet a deadline to make management that is technologically clueless happy. Even orgs that value good code have people leave because of the take a new job merry-go-round to get a good pay raise of years past. One of the reasons open source surpasses most closed source software despite a lack of funding is you a variety of individuals with different goals that are focused on making a maintainable and usable solution.
