Yeah; I saw a 29,000 line pull request across seventy files recently. I think that realistically 29,000 lines of new code all at once is beyond what a human could understand within the timeframe typically allotted for a code review.

Prior to generative AI I was (correctly) criticized once for making a 2,000 line PR, and I was told to break it up, which I did, but I think thousand-line PRs are going to be the new normal soon enough.
