The assumption here is that the AI-generated code wasn't reviewed and polished before submission. I've written stuff with AI and sometimes it does a fantastic job. Other times it generates code that's so bad it's a horror show.

Over time, it's getting a little bit better. Years from now it'll be at that 99% "good enough" threshold and no one will care that code was AI-generated anymore.

The key is that code is code: As long as someone is manually reviewing and testing it, you can save a great deal of time and produce good results. It's useful.
