You are correct to recognize that cell phones don't work well for a bunch of reasons as the cause. But your causes suffer some of the same problems. In particular, fertility rates are going down throughout the world, and have been since the 1970s, while almost everything you've listed is US specific in the last 30 years.

Tokamaks also have no solution to the fast-neutron problem, which "embrittles" the core components of the reactor itself into powder over a few years of operation.

Only magnetized target fusion, like what General Fusion is pursuing, solves that problem.

I'm not sure that fusion will ever reach economic viability. But they're literally the only ones that even have a chance.

The Washington war party pushed NATO right up to their border.

You mean countries who had escaped Russia's grasp asked to join NATO so they wouldn't get invaded by Russia. Fear of Russia made the Baltics ask to join NATO. And of course, Russia then invaded Ukraine, a country not in NATO, showing the Baltics were right to be worried. On top of that, to invade Ukraine and then continue its car with Ukraine, Russia had to remove troops along the borders with NATO countries, showing that the Russian government, for all its claims otherwise, understands that NATO is not a threat to Russia except in so far as it stands in the way of the Russia government's imperialist ambitions.

Do you mean fusion power? If so, it is worth recognizing that we've made major progress on fusion power with the average predicted time to fusion power going down over time. For example, the triple product, which is an important measure of how effective a fusion system is, has been growing since the 1950s. with a brief pause slowed down in the early 2000s when almost all fusion research money went into ITER and is now increasing again https://www.fusionenergybase.c... . Additionally, usion research has been drastically underfunded compared to what predictions of fusion being soon would have assumed https://x.com/ben_j_todd/statu... . .But even given that, the predictions by experts of when we're going to have fusion power gone down over time https://link.springer.com/arti... at about 1 year every 3 to 5 years. To some extent, the question for fusion is not will we develop it, but given the timeline, will it ever be cost competitive in practice against very cheap wind and solar whose prices are dropping rapidly.

The state of quantum computing is pretty similar. There's ongoing progress in a bunch of ways. There's been not just improvement on the physical end, but there's been improvement on the algorithmic end on how quantum error correcting codes and other needed algorithms would function, reducing the quality of qubits and number of qubits needed for applications. See for example https://www.quantamagazine.org/thirty-years-later-a-speed-boost-for-quantum-factoring-20231017/. Microsoft's 2029 claim is likely overly optimistic, but it is a mistake to think we're never going to have these systems.

As I've pointed out before, I have an actual PhD in number theory. I've explicitly discussed here specific results which are due to me and linked even to one of my papers before. You should be able to think that maybe, just maybe, people who are subject matter experts might know what they are talking about, and maybe know something you don't. But for some reason that possibility seems to be one you immediately and completely discount.

Good point. Obviously, a counter example is very simple in "proof structure", especially as it does not need to tell you anything about what an optimal result would look like.

The proof structure here is somewhat simple, enough that any algebraic number theorist can follow most of the argument. But that isn't because it is a counterexample. There are occasions where a counterexample requires an extremely difficult, delicate, construction and there are times where a proof of the claim in question is surprisingly straightforward. This is the sort of mistake that one makes if one a) Doesn't know as much about number theory as one thinks one does and b) have a lot of motivated reasoning going on to discount the significance of the result.

I'm a mathematician, so there's a chance that I maybe, just maybe know what I'm talking about it here. You appear to be using an extremely narrow definition of "leverage" and then insisting anyone who doesn't use your definition is wrong. But whether one insists on an overly narrow definition of leverage or not, the central point remains: when people make mathematical discoveries, they are building on and using existing ideas. Whether you object to the word "leverage" there isn't relevant to that central point.

This is a *famous* unsolved math problem. It was already highly unlikely that there was a solution hiding in the literature for Problem 1196. The Unit Distance Problem is so much more famous, with so much more work, it is genuinely hard to express how fantastically unlikely it was for this solution to be somehow hidden in the literature.

This seems to be somewhat incorrect. They also released the rewritten "cleaned" chain of thought here https://cdn.openai.com/pdf/1625eff6-5ac1-40d8-b1db-5d5cf925de8b/unit-distance-cot.pdf(pdf). That isn't everything, and has been cleaned in some respects, but shows a massive number of dead-ends, unnecessary complications, and everything else you expect to see in a working mathematician's initial attempt at a proof. As far as I can tell, the primary thing they've done here is just compile the text LaTeX into a PDF form but given that this is a proprietary model output it wouldn't surprise me if it also had some things they don't want to leak scrubbed from it.

Lemma 2.2 struck me as a type of bound on an extension with complex multiplication that I had not seen before and seemed clever. I was also struck by even as the Lemma itself was clever, that the proof of that Lemma was pretty straightforward. The overall approach is in many respects pretty similar to existing work and feels in some respects in the same spirit as Erdos's own lower bound construction, but having a tower of fields which seemed clever to me, but the writeup notes three prior papers where a tower was used to produce a combinatorial object of some type. That said, I still find this choice of the class field tower to be clever and intricate in this context.

I am mostly in agreement. Disagreement here:

The simple fact is, AI has gotten much better at solving unsolved math problems than humans are.

We're not at that point yet. Right now, we're not seeing it solve the genuinely hardest problems, like say the Riemann Hypothesis, or P ?= NP. What is true is that these systems are at least as good as a beginning grad student in all subfields and are outputting results equivalent to a top-notch mathematician on some problems. But it is also true that these systems are improving rapidly. So while your statement is false right now, it looks likely your statement is going to be true within just a few short years.

Au contraire. If you look at 1000s of problems and burn a mountain of tokens, you are bound to find some rare cases where everything was already there but nobody put it together.

Have you read the paper? I have, and it is very much not the case of what is going on here. There are multiple deeply clever bits in this argument. If this were written by a human, it would be recognized as highly insightful. Moreover, you are also missing how much what human mathematicians often do really does look like what you are dismissing. I've worked on hundreds of problems, and gotten successful results in maybe 5 or 6 of them. If someone dismissed humans under that basis, you'd recognize the problem.

And if you read the raw output of the AI, it looks a lot like what human mathematicians do. We try one thing. It fails. We try to look at a related theorem; doesn't generalize. We go check a few cases; doesn't give much insight, so we rope an undergrad into writing some code for us to go up a big more. Then, we're sitting in a seminar on a completely different topic, and trying to pay attention while the speaker does a really poor job explaining their research, we're like "Hmm, what if I tried to combine it with that other thing we saw 2 years ago." That still doesn't work. But then six months later, you bash your head against the problem a bit more trying to use some sophisticated representation theory results, and then you are falling asleep and you realize that other thing from now 2.5 years ago combines with a pattern the undergrad mentioned in the data that you didn't think was important, and you get a result. Mathematicians work by trying lots of different things on lots of different problems.
