The horror indeed, but I don't really see a way out of this. Was mainly curious to see how it would affect something like "Peer Review" though I suspect the incetives there are different so the processes might only shares the word "Review" without much baring on each other.
Regarding code reviews, I can't see a way out unfortunately. We already have github (and others) agents/features where you write an issue on a repo, and kick off an agent to "implement it and send a PR for the repo". As it exists today, every repo has 100X more issues and discussions and comments than it has PRs. now imagine if the barrier to opening a PR is basically: Open an issue + click "Have a go at it, GitHub" button. Who has the time or bandwidth to review that? That wouldn't make any sense either.
