Only reviewers can ensure that higher quality papers get accepted and no one else.
Which is to say, if there were four selections to be made from ten submissions, I expect that humans and AI reviewers to select the same winning 4 quite frequently. I agree with the outrage of the reviewers deferring their expertise to AI on grounds of dishonesty among other reasons. But I concur with the people that do it that it would mostly work most of the time in selecting the best papers of a bunch.
I do not expect there to be any positive correlation between papers that are important enough to publish and papers which embed prompt injections to pass review. If anything I would expect a negative correlation—cheating papers are probably trash.
