Yes, and no.
As someone who had studied and had taught math, I really like peer review.
But peer review is a powerful tool.
Carefully choosing what lemmas to give for solving and reviewing the result is my favorite way to teach young minds. Yes, they do solve most problems themselves. But, most of them likely wouldn't be able to do that before someone dissects problem beforehand and points at weak spots in their explanations.
And that's why I question who prompted the model, how they prompted it, and how much their own ideas influenced the output.
I admit, I don't know enough to judge how much of the right solution was actually enclosed in a first reply
like having a colleague peer review your paper, or bouncing ideas off a mentor before you write them down?
I agree there's a lot of AI marketing BS at the moment, but revising approaches based on feedback is a good thing.
