> more and more engineers are merging changes that they don't really understand

You cannot solve this problem by adding more AI on top. If lack of understanding is the problem, moving people even further away will only worsen the situation.

I agree, and that's why we're not building a code review bot which aims to take humans out of the loop

We don't think of Stage as moving people further away from code review, but rather using AI to guide human attention through the review process itself

Nobody thought of the other stages as that either. It still happened.

AI guiding human attention means that humans aren't guiding human attention, which means less human understanding of their reviews.

That leaves no solution when the quantity becomes more than any human can review.

This is like complaining that someone doesn't have a solution for the foot injuries caused by repeatedly shooting yourself in the foot.

If your team is shooting each other's feet and you can't stop them, I guess this would be a foot to air interceptor for some of the bullets.

The number of solutions remains constant, because the OP isn't providing a working solution.
