(And presumably to "understand", although that's not exactly the same as "checking", I guess.)<br /><br />In which case, even if we rely on future math AIs (or smarter people) to find proofs, at least there is a window in which we'll understand the proofs, even if we can't find them ourselves.<br /><br />I think that's (kind of) reason for optimism. (Although I guess at some point, even checking the proofs becomes difficult also.)Josh Burdickhttps://www.blogger.com/profile/12231348292069164630noreply@blogger.comtag:blogger.com,1999:blog-3722233.post-87131591735084689032021-11-01T13:43:24.605-05:002021-11-01T13:43:24.605-05:00That might be a good way of getting out of being o...That might be a good way of getting out of being on committees!<br /><br />But to be fair, as Dean's Rep its not my job to understand the material, though I would like to.

Together with the fact that math and CS seem to have a culture that allows them to really thrive in that environment.
