<p>I agree that the declaration doesn't focus on credit, but I think it's still at the root of the problem. Because ask yourself: if the AI generated proofs are not creating any new ideas or insight, just brute forcing a boolean true/false result, then why can't mathematicians simply ignore their results?  Why does it matter if OpenAI or even amateurs with AI are "solving" these problems, without contributing to any deeper understanding?<p>I don't think "intellectual poisoning" is really the mechanism that harms the mathematics community.<p>The harm is if you have a community of mathematicians who are focused on expanding human understanding, then having instant access to a bunch of AI proved results muddies the water about who has contributed what.  If someone could scoop any significant theorem at any time by pointing an AI at it, how do you really demonstrate that you have created new understanding? Or that your new understanding is about something important?  How do you prove that the AI needed <i>your</i> new concepts to be able to solve it?</p>

<p>To me it doesn't seem like what AI has destroyed is the ability for mathematicians to develop understanding and share it with each other, but rather it's destroyed the yardstick (solving open problems) that has traditionally been used to measure how much they have contributed to that understanding.<p>I do see how this is a problem in terms of assigning credit, but I think the cat is already out of the bag in terms of these models being capable.  Even without AI labs spending millions of dollars to solve millennium prize problems, there are plenty of other people who will use them to pick low hanging fruit.  I don't think any social solution is going to make things go back to the way they were, where you could share your progress towards a famous open problem without risking someone "scooping" you within a couple of days.<p>I think that the most likely outcomes are either mathematics becomes more secretive, or there is a more deliberative approach to assigning credit than who was "first" to solve some problem. In the former case, this may slow down progress, and in the latter case, this could mean that credit would become more subjective, and be a continual source of controversy.</p>

<p>Sorry, by harder I meant for the same number of faces.  E.g. the article is about 5 60 sided dice, which was a breakthrough,  but there are other known solution where all the dice are less than 60 sided, but they are unequally sized.</p>

<p>The key part is that they have to be fair when any subset of the dice is rolled together, not just when all five are rolled.  Also if the dice are allowed to be different sizes then it's easier as well.</p>

<p>Just going to add my commentary as someone who has trained LLMs and understands them deeply: absolutely nothing he has posted in this thread suggests he lacks any relevant understanding of how LLMs work. If you disagree, you should point out something specifically that you think was wrong.  (And honestly you should have made a specific point in your first post).</p>

<p>I had a similar thought when I did a file by file review of a large codebase for bugs, and Claude commented at the end "the worst file was foo.cpp", which happened to be one of only a few files I hadn't mostly written myself. It made me field proud for a second, and then uncomfortable thinking how it had access to the git history, and surely it could predict I might feel complimented...</p>

<p>What is a meal though?  Do you get the same volume of food from all vendors, and the same number of calories?  I definitely order multiple items from restaurants that have small portion sizes, so I suspect some vendors would be better or worse deals even at a uniform price.</p>

<p>I don't see why having ASI would make the top 0.001% <i>less</i> interested in using the energy, minerals, and land on earth. Just because they have no interest in your labor doesn't mean they have no interest your house or your energy supply.  "Humans will be so rich they will fuck off to other parts of the world and leave gorilla habitat alone" hasn't really panned out so well.</p>

<p>I don't like saying "oh this is AI generated" because of exactly this scenario, where maybe there is care behind it and you just used AI to help you write.  The problem is that as a reader I have no way to tell, and aillI have a lot of experience reading AI generated writing where it's subtly incorrect or misleading.<p>I would really suggest you rewrite the README, to remove the cliches and make it clear how much effort you put in.  You clearly are able to communicate well about this project on your own.</p>

<p>I looked into open source sensor fusion libraries for open mower, it seemed like the WOLF framework was very promising as a pluggable sensor fusion system.  <a href="http://mobile_robotics.pages.iri.upc-csic.es/wolf_projects/wolf_lib/wolf-doc-sphinx/index.html" rel="nofollow">http://mobile_robotics.pages.iri.upc-csic.es/wolf_projects/w...</a>.

<p>Against Malaria Foundation | Senior Software Engineer | Remote (UK) | Full Time<p>The AMF works to fight malaria in an extremely cost effective way with insecticide treated bed-nets. Every year hundreds of millions of people will be infected with malaria, and half a million of them will die, with many more being debilitated or disabled. Independent charity evaluators, such as GiveWell, have ranked the AMF as one of the most cost-effective charities in the world for over a decade, due to our long and well-studied track record preventing hundreds of millions of cases of malaria.<p>Our tech team is just a couple people, and all-remote. Our software is essential to the charity work we do; it is one of the ways we stand out among other charities, by allowing us to automate, analyze, and validate our work in novel ways.  Our tech stack includes C# .NET, Blazor, and Python.<p>If you are a senior SWE in the UK who is interested in making a difference, please reach out to me by email at my first name at againstmalaria.com</p>

<p>Just because you state your opinion confidently, does not mean you are correct.  For example, as of 2024, there are 30 billion kilograms of proven reserves of lithium, more than enough to replace every single one of the 1.5 billion ICE cars in the world with an electric car.

<p>Does anyone know of a board state that doesn't involve arbitrary actions, but a specific finite setup, which would nonetheless require the solution of an unsolved conjecture in order to resolve who wins?<p>I am thinking of an example like constructing two incredibly large numbers (of the same sort as grahams number) where it is not known which is larger, and then e.g. doing x damage to a creature with y health.  Ideally this happens in a way that nobody would object to the construction if x and y, since they are simple to describe and construct.<p>I understand that you can construct a turing machine to perform an arbitrary computation, but that defeats the spirit of this question.  The question is whether there is a simpler way to construct such a paradox where you might follow along happily until you get to the end.</p>

<p>I'm not sure I agree.  I think just having wings that flex a bit is mechanically simpler than having an additional rotating propellor.  After all, rotating axles are so hard to evolve they never almost never show up in nature at a macro scale.  Sort of a perfect analogy to lidar actually.  We create a new approach to solve the problem in a more efficient way, that evolution couldn't reach in billions of years</p>

<p>As someone who implemented some RL algorithms and applied them to a real world game, (including all the ones mentioned in the article), I would be surprised if the implementation is not buggy.  That is one of the most striking things about RL, the extent to which it is hard to find bugs, since they generally only degrade the performance instead of causing a crash or obviously wrong behavior.  The fact that he doesn't mention a massive amount of time spent debugging, and the longish list of things that were tried that really <i>should</i> have worked but didn't, suggests to me it's probably still buggy.  I suppose it is possible that LLMs could be particularly good at RL code since it's seen it repeated so many times... But I would be skeptical without hard evidence.</p>
