    I wonder if we’ll end up in a weird situation a decade from now, where every conjecture will collapse into one of two states: counterexample found by AI, or assumed to be true.

      No way. Mathematicians don't assume things to be true even if there are no counterexamples.

        Agree. I give up isn't the MO of many with graduate degrees.

        Generally, no, but sometimes, yes.

        It can be productive to assume something is true and see what happens.

        It depends: there do exist some conjectures for which there don't exist any proofs, but a huge amount of results assuming this conjecture (which is very near to assuming that the conjecture is true). Examples are:

        - Riemann hypothesis [1]

        - Generalized Riemann hypothesis (GRH) [2], and potentially also Extended Riemann hypothesis (ERH) [3]

        - Standard conjectures on algebraic cycles [4]

        - perhaps Schanuel’s conjecture [5]
