Yes most people are not top tier devs and most code is slop whether written by AI or not. I've probably dug through tens of thousands of code bases in my over 30 year career as a software engineer and most are slop.

I also did not claim that all "top tier devs" would always produce better code with AI, but the qualification for a "top tier dev" in this case would be someone who verifies code multiple ways to make sure it is correct. I've seen amazing code come from bad interns that was reviewed mercilessly by season devs, and there's absolutely no reason it would not be the same with AI generated code.

You do realize that you can review the entire architecture and code line for line even if it's AI generated right? My black box comment did not mean you couldn't see the code, it meant you don't know whether a machine wrote it or not.
