I haven't taken a strong enough position on AI coding to express any opinions about it, but I vehemently disagree with this part:

> This is like reviewing your own PRs, it completely defeats the purpose.

I've been the first reviewer for all PRs I've raised, before notifying any other reviewers, for so many years that I couldn't even tell you when I started doing it. Going through the change set in the Github/Gitlab/Bitbucket interface, for me, seems to activate an different part of my brain than I was using when locked in vim. I'm quick to spot typos, bugs, flawed assumptions, edge cases, missing tests, to add comments to pre-empt questions ... you name it. The "reading code" and "writing code" parts of my brain often feel disconnected!

Obviously I don't approve my own PRs. But I always, always review them. Hell, I've also long recommended the practice to those around me too for the same reasons.
