<p>In practice, mathematicians' workloads have been a function of their work ethic, motivation, and competing demands on their time. There's no big-picture question of "how much math there is to do now"; the amount of remaining math to discover has long been presumed to be, for all intents and purposes, infinite. (Similar questions <i>are</i> relevant on a much smaller scale -- for example in case of someone who has specialized in a narrow specialty which goes dead.)<p>Your (1) is most certainly true.<p>As for your (2), most mathematicians I know have at most a passing interest in formalization, Mathlib, and Lean. My understanding, which is admittedly quite superficial, is that AI is actually getting quite good at translating human-readable mathematics. I could be mistaken about this, but even if there is a lot of human work to do, it sounds like a lot of anal-retentive oversight of work you didn't do yourself -- the sort of task that academics love to complain about!<p>Perhaps human interest in Lean will grow, but I don't anticipate it occupying the attention of more than a small slice of the community.<p>Your (3) is an interesting question. I work on the theoretical rather than applied side, but what you describe might very well be true for applied mathematicians.</p>

<p>As a mathematician, summer salary (from grants) is nice but I could do without it.<p>But external funding, e.g. from the NSF, also supports conferences -- and I suspect that few people would be willing to attend if they had to pay out of pocket. Without this opportunity to talk to one another, the field would be much worse off.</p>

As one possible model, check out this blog post of Terry Tao's, where he gives his own perspective on the recently proved Jacobian conjecture.<p><a href="https://terrytao.wordpress.com/2026/07/21/a-digestion-of-the-jacobian-conjecture-counterexample/" rel="nofollow">https://terrytao.wordpress.com/2026/07/21/a-digestion-of-the...</a><p>When computers can solve the underlying actual problem, this sort of work seems likely to rise in value, and be something which a greater number of mathematicians engage in.</p>

<p>I'm a mathematician. I have a <i>lot</i> of trepidation about these tools and what they mean for the future of the profession.<p>That said... most of us are not working on problems as famous as Navier-Stokes. Even if OpenAI could scoop me based on my back-and-forth with ChatGPT, which I presume they could if they threw $15 million worth of compute at it, I highly doubt they'd bother.</p>

<p>> those universities that do want to do that<p>As a university professor, I've seen that all universities want to do everything.<p>By which I mean, they employ all sorts of people who are pushing a huge range of agendas. You can't meaningfully speak about "what universities want", because various factions tend to expect free rein to pursue their goals, and there is no mechanism to get everyone pushing in the same direction.</p>

<p>I'm a research mathematician, and to me the biggest surprise is that the user didn't identify themselves or (yet) try to claim credit for their work.<p>Within academia, it is to your <i>definite</i> advantage to have your name associated with breakthroughs, for obvious reasons. Outside academia I don't have firsthand experience, but I'd have to imagine the same holds.</p>

<p>> The record before this morning was 29 and people suspected that was as high as it got.<p>Exactly this. A fundamental question in the subject is, whether elliptic curve ranks are bounded. Contrast with e.g. prime numbers, of which are known to be infinitely many. If you set a new record for the largest known prime, then that's cool but everyone knew there were plenty out there to discover.<p>This paper, by leading experts,<p><a href="https://arxiv.org/abs/1602.01431" rel="nofollow">https://arxiv.org/abs/1602.01431</a><p>made a significant impact in the field, coming up with a heuristic argument for why ranks of elliptic curves should be bounded. The same heuristic suggests, albeit more loosely, that we should perhaps be a little bit surprised to see a curve with rank at least 30. So it's mild evidence that the heuristic itself could be mistaken.</p>

<p>Mathematician here. There is a lot of recent work on the Lean project -- when a proof can be translated into Lean code, then it can be strictly and formally validated.<p><a href="https://lean-lang.org/" rel="nofollow">https://lean-lang.org/</a><p>But otherwise, mathematical proofs are read and written by humans, and at the end of the day the relevant standard of proof is what other mathematicians will accept.<p>Occasionally, mathematicians don't agree. For a prominent example, you can read about Shinichi Mochizuki's claimed proof of the so-called ABC Conjecture:<p><a href="https://en.wikipedia.org/wiki/Abc_conjecture#Claimed_proofs" rel="nofollow">https://en.wikipedia.org/wiki/Abc_conjecture#Claimed_proofs</a></p>

<p>Guess I got spoiled by reading Kant in one of my college classes. He was all about trying to describe morals based on rules.<p>That said, picture someone killing a kitten and someone else killing a cockroach. One could prevaricate all day with highbrow reasons for why the first is monstrous and the second is perfectly moral -- but honestly, for most people, I suspect it comes down to the fact that kittens are cute and cockroaches aren't.</p>

<p>How are you distinguishing them?<p>I had the impression they were essentially synonyms, and this was borne out by two university courses in philosophy which I took. That said, googling "morals vs ethics" turns up quite an interesting mess. A variety of contrasting perspectives showed up:<p>- Ethics come from an external source, whereas morals come from within<p>- Ethics are rational and structured, whereas morals are more emotional<p>- Ethics is a philosophy or code of behavior, whereas morals refers to beliefs and conduct<p>- Ethics and morals are used interchangeably<p>It seems nobody agrees on what the words mean. Which, on reflection, tracks. For me, the idea of an HR training session on ethics is laughable, but for someone who thinks of the word differently it could certainly make sense.</p>
