My observations align with this pretty closely. I have a number of colleagues who I wager are largely using LLM-s, both by changes in coding style and how much they suddenly add comments, and I can't help but feel a noticeable drop in the quality of the output. Issues that should clearly have no business making it to code review are now regularly left for others to catch, it often feels like they don't even look at their own diffs. What to make of it, I'm not entirely sure. I do think there are ways LLM-s can help us work in better ways, but they can also lead to considerably worse outcomes.
