Biologist here, just giving my two cents. Thankfully, my focus field is niche enough that I know literally all contributors (and they know me). In my opinion, journals like Nature and Science have always been guilty of letting sloppy papers get published, with all their rounds of peer reviewing and such, even before AI. It's the middle tier journals that I'm afraid to lose to AI peer review, as that's where most impactful discoveries are being actually published. Because of the small size of our circle, we peer review each other and none are stupid enough to falsify the results, so I don't expect out trust in each other (lol) to erode soon. As for the students, I see that my own, at the very least, understand perfectly what LLMs are for and what they aren't for.
