By far the largest review-effort PRs of my career have been in the past year, due to mid-sized LLM-built features. Multiple rounds of other signoffs saying "lgtm" with only minor style comments only for me to finally read it and see that no, it is not even remotely acceptable and we have several uses built by the same team that would fail immediately if it was merged, to say nothing of the thousands of other users that might also be affected. Stuff the reviewers have experience with and didn't think about because they got stuck in the "looks plausible" rut, rather than "is correct".

So it goes back for changes. It returns the next day with complete rewrites of large chunks. More "lgtm" from others. More incredibly obvious flaws, race conditions, the works.

And then round three repeats mistakes that came up in round one, because LLMs don't learn.

This is not a future style of work that I look forward to participating in.
