In a business (or any large project setting) where there are real users and real risk involved, code can't move into a code base any faster then it can be reviewed by a human. Period. I apply the exact same standards to PRs for AI assisted code as I do for human written code. If the code is crap, the PR is too larger, or the dev can't explain it. it gets rejected. End of story. We are a long way away from the need for human review going away.
