<p>I have to confess to being wrong in exactly that way in the past. On the other hand it is probably always good to behave as if the next step up in the hierarchy is still available. There's no point letting these things spoil your day twice.<p>Now I'm forced to think about it much more carefully. I don't believe that current LLMs can find every possible proof on their own from now on. I also agree that the PR returns have fully diminished. Given how hard it's been in recent years to fund e.g. a poorly paid postdoc, I doubt there's a ton of money lying around for getting the best models to work on mathematics problems. I think there's a chance we're heading into a really good era. I was able to make so much progress back when Google search was a useful research tool...</p>

<p>I think a lot of people are tempted to define the people they disagree with as idiots. Not all of them write down their thoughts at length. Both the verbosity and the edgelordery seem to be part of the culture of that community rather than inherent consequences. I think the sequences and HPMOR started or popularised a sort of norm that length is indicative of serious thought.</p>

<p>Once you decide that you believe what you believe because you are very smart and almost always believe true things, and the things you believe just happen to be the true ones (I am being unfair but I think this is the psychological effect of this so-called rationalism) it's not a big leap to: everything I have to say is worth hearing.</p>

<p>As a theorist, it's sort of true that I "don't care" about galactic constants. I'm interested in the structure of computation for philosophical reasons. But I really do care about the model of computation.<p>To put it another way, the constants inside a big-O are not really constant: they depend on what you assume is a constant-time operation.</p>

<p>Czech republic has some really nice quarries and dams where you can swim for free or next to free. One thing I've noticed is that Czechs only seem to go to such places when it's really really warm. So they're often empty even when they're perfect for swimming. At least the ones near me in Plzeň. I grew up swimming in the Atlantic so my idea of swimming temperature may be different to average Czechs!</p>

<p>I'm hoping and actually expecting that eventually there will be a simple way to locally host a small model that is good enough for simple things. For a lot of use cases, the capability of free chatgpt one year ago was more than enough.<p>Maybe there already is! But last I checked it was a little bit of a mess of manually installing things from multiple websites with little documentation.</p>

<p>Here's a dumb question. If there was just one tax, the lvt, what would stop businesses sort of rediscovering income tax.<p>I mean putting a line on your pay slip called "lvt contribution" and then state the pre-lvtc salary in job descriptions and stuff like that.<p>Similarly with vat and related taxes. The incentive in both cases being to signal: here's what we would pay/charge if it weren't for the government. Which is presumably the current incentive to state before tax salary/cost (this assumption could well be totally wrong).</p>

<p>Crazy take. Whatever justification existed before exists now. Why is generation of proofs justified but not understanding? What's the point of a proof if no one understands?<p>And anyway a mathematician's lifetime salary is basically nothing. I think total worldwide mathematics budget is less than a tenth of a percent of GDP. Meanwhile, openai cumulative loss stands at tens of billions?</p>

<p>Reading between the lines here, and taking an admittedly very negative view of openai, but they train on user prompts. So if they hear a rumour that someone is about to make a big breakthrough, they have an incentive to scoop by running the model and hoping the solution is in the new training data. Also the statement from the mathematicians in question alleges that they tried to pressure him into academic malpractice. Just appalling timeline we're in, cheers.</p>

<p>I just read that book. Embarrassingly enough, given the context, I got chatgpt (or whatever) to recommend me a list of books based on ones I'd previously enjoyed and that came up. As a mathematician it really sang to me, given the current situation. Bearing the torch forward, I mean.</p>
