I understand that the real proof of the RH is the friendships we make along the way, but what would happen if we just acted with the assumption that it is true?
Still, a number of people who've worked most closely with the Riemann zeta function, even the ones who led the computations and numerical verifications, have expressed doubts on whether the Riemann Hypothesis is actually true: https://arxiv.org/abs/math/0311162
Of course there is hope that a proof of RH would reveal some deeper understanding -- not merely a conformation.
Do you know if anyone has tabulated stats on conjecture proofs? That could be a fun dataset to examine.
