As others have said this before, AI is a tool and it is not supposed to nor should replace thinking. Unfortunately many people does not abide by this. See the other submission where people made a 128k line PR to a project: https://news.ycombinator.com/item?id=44729461.
It is clear that the guy responsible for this PR outsourced thinking. I would call it "misuse of LLMs". LLMs get a bad rep because of individuals who completely outsource thinking.
For all its failings, SO strived for a very high signal-to-noise ratio, and it achieved it.
