That seems like wishful thinking. Why wouldn’t AI be able to assess what are good questions to humans, and pursue similar processes as those that lead humans to come up with good questions? AI is trained primarily on expressions of human thought and emotion. It’s difficult to see what secrets of the human brain we could be hiding from the models.
Anyone who thinks they can predict the future of this technology more than a few months out is foolish, but the models got so good at answering specific questions in math because the frontier labs could use RLVR to train them. There is no RLVR for mathematical taste.
Because s/he is pulling this claim out of her/his rear end.
