> Like I think (or know) code reviews are also over.

Whatever the size of code review chosen, merging totally unreviewed code to prod is still totally insane. There are a few AI code review products out there. The one I've used is fairly decent at picking out issues, though there's definitely some shortcomings vs a human reviewer with additional context (especially since not everything is written down for the bot to access). So I wouldn't say they are over. Even though the AI review isn't perfect, we all know human reviews aren't either.

As AI improves it'll be able to hold more of the codebase as context, enabling better, quicker reviews.
