I think these are non-trivial epistemology and science theory problems.
Suppose an oracle tells us the Riemann Hypothesis is correct. There are a vast number of results of the form:
If RH is correct then A.
It would be very useful to have an oracle tells us whether or not RH is correct.
We all believe it. It's a magic oracle. Now what?
But one can already study the consequences of P=NP right now. You don't need to know that it's provably true in order to do that.
Knowing an actual proof would be useful, but an oracle revealing merely that it's true (or even provable) without telling you the proof does not let you do anything you couldn't do before.
For what? Which product becomes better if it is correct?
I have published mathematics so I do value knowledge, but for most of mathematics the value of the knowledge isn't the thing you try to prove it is all the things you learn as you try to prove it. p = np is one such thing.
So the whole interesting bit about it is the proof, not the fact.
For what? Which product becomes better if it is correct?
This sentiment is anti-thetical to the whole point of pure math and theoretical science. No product became better when Euler proved the fundamental theorem of algebra.
Somebody, eventually, somewhere would understand it, or at least aspire to understand it. And even if he doesn’t, what have they learned in the process? About themselves, about their environment? About failure? I would bet a lot. How useful then, can we say that it is, not because we can understand it, but because we can try? That is useful. This is about the journey. Sometimes the journey is the point.
This is like if math was fascist, this is what would happen. When you start controlling the flow of knowledge like this, it will be bad news all around. And who is to say whether or not something can be understood?Aside from the math nazis.
If we are going to dictate what gets published like this, why bother publishing anything? This feels like a gatekeeping…that’s exactly what it is. Ya’ll getting nervous?
In any case, I think it's better to read PP as somebody would find a practical, albeit incomprehensible, algorithm for solving NP complete problems.
Although I probably disagree with PP, because even a candidate algorithm that mysteriously works without proof would have practical value, so this case is not predicated on proving.
I think a better example of genuinely practical but rather uninteresting (YMMV) mathematical proofs are proofs of convergence of numerical methods, FEM for example. (I have been through it in school, it was a torture.)
It would not not necessarily be practical, even if it ran in polynomial time. It may have cost O(n^c), with a totally out of order exponent like c=A(5,5) or whatever.
Furthermore, careful analysis of the latter would as likely as not yield further understanding and, actually /would/ help finding such algorithms.
Finally, it has been observed time and time again that often (again, nothing comes up and i don’t want to ask AI) the certainty that something is possible and has been done is motivation and inspiration enough for people to independently solve a problem. Sometimes it is even enough for someone new to simply not know that something is “hard” to solve.
It even “motivates” llms, it seems (eg https://cdn.openai.com/pdf/04d1d1e4-bc75-476a-97cf-49055cd98...)
Of course this is all pure speculation concerning a hypothetical proof that most likely doesn’t exist, or indeed might be so complicated as to not be approachable even after hundreds of lifetimes of study.
Nevertheless your conclusion does not follow from the premise
We only compute with two kinds of things:
- small data; or,
- extremely lower power and coefficient algorithms
We lack the power to, eg, use a quintic algorithm in anything but nearly trivial cases.
You would need an algorithm that finds solutions, not just a proof they exist. So the value here would almost entirely come from how you proved p = np, since that proof will probably be the first step towards finding the polynomial solutions. But if humans don't understand it good luck finding any.
Is Amazon still delivering food to your cat?
Humans don't need to understand what AI generates. We still can get the rewards.
In reality, it wouldn't depend on the truth value of the statement, but on the AI understanding the proof. If it understands it then it might be able to use it to find reductions.
So the point remains, knowing that P=NP isn't what's important, it's the proof that matters.
Memorized proof patterns have value because they lead you to a final proof.
Imagine if humans couldn't understand multivariable calculus, but we had access to an AI system that developed it, it initially seemed useless, then another AI system found a predictive model of electromagnetism using it.
When you have full AGI of course you no longer need humans to understand math.
> Imagine if humans couldn't understand multivariable calculus, but we had access to an AI system that developed it
Developing multivariable calculus requires much more than just solving problems though, it requires defining an entirely new system and space. That is not the situation mathematicians face today, modern AI cannot do that.
When talking about mathematicians and AI don't use fictive examples, we can look at what AI can do today and extrapolate that they can do more of that tomorrow, that is what we have to work with.
In the case you posit where AGI exists there is no reason to even discuss what is left for humans to do, since AGI is defined as when humans are no longer needed for anything, the AGI can do every bit of thinking humans can.
The idea of AI stepping from a graph theory/combinatorics innovation to some new and useful algorithm isn't crazy.

IIRC he has expressed support in the past for attempts to formalize IUT in Lean, but we'll see where that really goes, because he's absolutely not clearheaded enough to lead such a project himself.
That said, without understanding, Math can't evolve. Comprehension of a proof is very important, but not what Math is fundamentally about.
Computer programs are Math. You can use them without understanding how they work.
Secondly, there is no truly objective truth to the area of a triangle. At bottom, this “truth” is simply “everyone is convinced, and for good reason”.
Without persuading other people of the “truths” that you discover, there is no real mathematics.
Why? If I sat around and studied math by myself and discovered something true yet not yet known but didn't share it, it's still true. Are you saying I didn't "do math" because I didn't share the result? Math exists on another plane and it has 'truths' that we haven't discovered, yet are still 'true', no?
The area of a triangle doesn't have 1 unique formula, it has many, depending on the system you use. A triangle in plane geometry has a different area than a triangle in spherical geometry, and different again in hyperbolic geometry.
When you get to studying the geometry of manifolds, you realize the area of a triangle can be any damn thing you want, depending on how you construct the manifold you embed it in.
Math has been almost purely arbitrary since ~ late 19th/early 20th century. There are uncountably many correct mathematical theorems. Almost all of them can't even be written in symbols. Even if you have a tape with infinite length (which is already longer than the whole physical universe!) filled with theorems, they are still only 0% of all correct theorems. That's how arbitrary math is.
> The area of a triangle
Yes, even this is arbitrary. The rigorous definition of triangle is arbitrary. People just subconsciously choose something that vaguely approximates their physical intuition.
You seem to be vaguely waving in the general direction of a point, without making any concrete claims or bothering to engage with the GP’s argument.
The tastes and interests of humans are absolutely not arbitrary. They are dictated by fate, the sun and the moon gods. Or maybe by the unitary evolution of the universe’s quantum state. Or by the probability distribution of finding ourselves in a particular branch of the universe.
What bearing does this have on whether math is a collaborative endeavor?
And what is unique to math, that your argument wouldn’t apply equally to physics, sociology or financial markets? All, “truth seeking” disciplines.
Whatever philosophy you prefer, math is about establishing objectively valid logical results, completely independent of the human process used to arrive at them.
Mathematicians even argue which axioms we should have, it isn't objective in the slightest, mathematics is therefore very closely linked to our feelings and intuition. Remove that and you just have formal logic, a very different field.
From my perspective, I feel you restated what I said with the opposite conclusion. You say that axioms "defines" mathematics. If I were Claude, I'd say that the word "define" is doing a lot of work, is load bearing or something like that.
"Define" is where we turn these axioms into consequences - what I call "truth". As opposed to all the other stuff people could say that don't follow from these axioms. These are nonsense and, most certainly, un-mathematical.
it starts as a tool for humans, then evolves into a set of interesting properties of those tools, then grows into an art form, a set of "games" where cooperation is half of the point. the other half is discovering beauty in this weird parallel world of our reasoning and imagination. once tools become autonomous and start making up their own games we can't even play then mathematics loses it's meaning as a discipline. the only retort you can come up with is that "it's going to be useful". how would you know? because your autonomous tool that's too smart for you told you so? they could be as useful as morning orange juice to Claude Shannon was in terms of inventing information theory. I.e. you drinking it won't make you any closer to inventing anything of the sort anytime in your lifetime.
do triangles exist IRL? is the world discrete or continuous? can you prove it? If you have an answer to all of those I know you're wrong.
also in your computer program example just shows you don't understand it at all. those programs ARE NOT understood by you, but someone else who built them did. someone who bothered to read and architect it did. The whole Google codebase might be incomprehensible in its totality if you go bottom up but it is comprehensible by construction by us. Same with math. You don't understand all the bits of it, but someone built every brick and so you know it is "true". once the bricks become black boxes you're screwed.
In history, we made much more use of hitting things with bows than abstractly comprehending arrow flight.
In that setting, field experts working at the bleeding edge are so advanced that non-experts literally can't understand what they're saying at all. So there's a whole class of specialists, "synthesists", that specialize in gaining approximate understanding of the experts' work for the purpose of communicating it to outsiders—perhaps wrongly, according to the expert at least, but hopefully more productively vs the unmediated version.
https://en.wikipedia.org/wiki/Collatz_conjecture#In_proofs_o...
> In July 2026, a disproof of the Collatz conjecture was verified not only by Lean, but another formal verification system Nanoda. However, investigation quickly revealed that the proof exploited bug(s) in these verifiers.
The core of Lean got a lot less correct when a well-meaning AI system probed Lean for corner cases (bugs) that would "prove" a false conjecture. Corner cases so arcane that no human exploit in a proof. Basically, humans are too stupid to break human-created Lean, but the AI is not.

(N.B. from August 2026)
My point was rather more motivated by having seen so many weird ways for machines to fail/not work as expected that I wonder how to deal with that if the output were to be incomprehensible to humans.
Why does this tend to be the case, even when some of the smartest people in the world have historically predicted incorrectly that certain branches of math would forever be useless (e.g., number theory)? I can only offer my own theory on that, but my guess is that mathematics is simply a predictive framework based on pattern compression. A more powerful pattern compression framework accelerates every single field that relies on pattern recognition or prediction of the unknown based on patterns.
The output might make a cool screen saver as-is, but we probably need a way to evaluate it somehow.
Let me make up an example of where I could imagine this going. Something we essentially cannot do right now is predict coarse-grained phenomena from systems that involve millions or trillions or more of interacting components. Over hundreds/thousands of years of experiment and theory we've derived laws that essentially do this in a few special cases, but we have no systematic theoretical way of doing it in general, and frankly I think it's beyond human ability. Whatever deep patterns or structures exist for doing this in a general way I think are simply out of reach for us.
That's a misconception. Only a tiny percentage of mathematics has seen any applications whatsoever. There are vast libraries full of mathematics no one (in this discussion, anyway) has ever heard of that no one reads anymore and has never been applied to anything.
This idea of trying to "prove all the math" with AI makes as much sense to me as using chess engines to try to "solve chess."
And that's an issue why? It would seem to me that producing that also produced the mathematics that revolutionized the world repeatedly for centuries. I would go further and claim that, if you want the mathematics that revolutionizes the world, there's no way to get it without advancing mathematics as a field broadly. Those are not two separate activities, and thinking that they are is indeed a misconception.
> This idea of trying to "prove all the math" with AI makes as much sense to me as using chess engines to try to "solve chess."
You're right: "prove all the math" does not make sense on any level, and nobody serious would phrase any of this in that way. I certainly didn't.
The issue is SNR: signal to noise ratio. Generating exponentially more mathematics, particularly if the process is indiscriminate or optimized for something other than usefulness or mathematical relevance (such as optimizing for machine-provability), does not imply that we get exponentially more applications. We may end up halting the progress of applications altogether as the entire capacity of the world's mathematical apparatus is consumed by the interpretation and investigation of machine-generated proofs.
You can already visit arXiv and find vast numbers of not-yet-published mathematical papers. Most should never be published. None of this junk is benefitting humanity in the slightest.
Moreover, the disdain you have for low-value output in mathematics is not unique to you. Talented mathematicians don't like it either. Your mistake is assuming that AI will cause math to be dominated by low-value outputs. In fact, the opposite is likely the case: the marginal value of proofs will fall so low that the bar for meaningful research will become dramatically higher, not lower. I expect the goals of research mathematics to become extremely ambitious relative to the past, organized around substantial and enormous goals, not mass-generated slop as you're imagining.
Of course, yes, there will still be lots of slop, just like GitHub is full of AI coding slop, LinkedIn is full of slop, etc. But that's a generalized issue of the AI era, not unique to math.
I didn't say anything about low-value output. No one actually knows the value of any particular piece of mathematics within that deluge. Mathematicians don't have a magical ability to differentiate high-value mathematics from low-value merely by reading paper titles and abstracts.
The dirty secret in the mathematical world -- that has been going on for a long time already -- is that papers get attention based on the reputation of the authors, not on the rigour or validity of the proof. The big headline-grabbing papers are getting read by mathematicians because AI researchers have leveraged media exposure to bypass the reputation network, but media exposure doesn't scale.
When everyone is using LLMs to generate proofs, only reputable mathematicians will be able to get their work read. And herein lies the crux of the problem: an exponential takeoff in the volume of output from respected mathematicians will leave a critical shortage of readers.
it could end up being far easier to reasonably direct and evaluate the research direction and output of AI systems than human mathematicians
That's baseless speculation. All indications so far are that LLMs produce proofs far longer and far more complicated than humans are capable of, such that only machines can check the proofs for validity. Digesting them into a human-readable interpretation of the results is an open problem.
False. You very plainly did. You simply used the term “junk” instead.
> That's baseless speculation.
It might be speculation (as is much of what you’re writing), but it’s not baseless. Obviously, it’s quite easy to direct AI agents, a single one of which can pivot across all of mathematics, unlike all human mathematicians.
> All indications so far are that LLMs produce proofs far longer and far more complicated than humans are capable of, such that only machines can check the proofs for validity.
I’m unaware of any clear evidence of this. Hence, it appears to be baseless speculation.
> Digesting them into a human-readable interpretation of the results is an open problem.
I’m unaware of any clear evidence of this. Hence, it appears to be baseless speculation. Moreover, and more importantly, to my knowledge there hasn’t been any meaningful result in AI mathematics so far that has posed any kind of blocking issue on understanding it yet.
I'm deeply suspicious. I do not yet have a concise statement for why, but a lot of literature on the sociology of knowledge work sort of points at my thoughts.
Section 5 of the Thurston article cited by Tao touches the elephant. Raduchel's article on the economics of software [2] also touches it.
I've tried to put words to this for a few years. I think I'm just going to start writing versions of it as see if that helps me shape the thought into something more concise.
So, in the spirit of this article's style, here are some postulates:
1. There is a sociological process happening in the production function during knowledge work.
2. That production function and the associated sociological process spans years or even decades, and must outlast many of the artifacts that are produced during the early years of the function.
3. You cannot get the right lines of code or the right theorems proved without running that sociological process alongside the artifact production process.
4. It is impossible to completely separate the sociological process from the artifact construction process. If you just iterate on artifacts then too much of the required hidden state is lost to make progress in the right direction. This is true even if you include distilled artifacts capturing pieces of the sociological process (eg meeting notes, documentation, commit logs, prompts).
5. So you need that sociological process, or something like it, to still happen.
6. For a lot of knowledge work that process plays out in extremely high-fidelity social interactions [3] that we have not yet captured in the datasets that would be required to reproduce those dynamics.
7. And even if we do collect that data, our current architectures and training algorithms and hardware would be useless given the size of the datasets.
So: the technology today gives us the ability to iterate on the production of artifacts. But it does not sufficiently simulate the social process which gives rise to the Right artifacts.
This isn't exactly what I actually think, but it's a version of the thing that I intuit when I watch heavy use of AI in both software projects and formalization projects. And simulating that process feels way harder than people are currently assuming.

[3] there is a reason we still gather in-person around white boards, and why doing so is more crucial for some types of work than others.
Properly explain is an enormous grey area. Soon, I think, there will be proofs of results that are verified in Lean that are so long that no one will be able to “properly explain”. I don’t think they should be discarded.
Resolution of singularities is a famous theorem of Hironaka. Abhyankar claimed that no one truly understood the proof of the theorem. He said that he and Zariski couldn’t get through the paper with a full understanding. But everyone accepts this theorem as being correct.
I could prove anything by claiming I completed a trivial-to-explain exhaustive search. The only support or refutation would be someone doing their own search. It's a very weak foundation.
We already had the ABC conjecture crisis: A theorem with a human-written proof so complex that no one besides the author can understand it. Some people claim to have refuted it. Most mathematicians are unqualified to decide.
Hmm, doesn't it take an expert to explain why those cases are exhaustive, and why the code that checked them is correct?
Tangentially, I'm not a mathematician but I wonder if one "opaque" proof that is too complicated for anyone to understand, but that we know is correct via formal verification, might end up being built on with "transparent" human-understandable proofs. For example, it's my understanding that there are many conjectures that have been proven true conditional on the riemann hypothesis being true. In that case, an opaque proof of the riemann hypothesis would enable those conjectures to be known and built upon
To your first point. There a large number of cases that maps can be reduced to. Very few people have checked these reductions themselves. In 50 years there will be no human alive that will have checked the reductions by hand. Do we then discard the theorem? More importantly, do we trust the people that claim to have checked all the reductions? There are hundreds of cases. I trust a computer verification much more than I’d trust human verification. Humans will likely make mistakes due to the tedium. And some will claim understanding of all cases but be wrong in their understanding in some of the cases.
Just burn lots of tokens on the frontier model of your choice to let the AI find a high-level argument why the four color theorem holds. :-)
--
Seriously: since there exist quite a lot of readers on HN who are both hardcore into AI and mathematical problems: This is a challenge for you.
I am looking forward to seeing an announcement of a novel high-level argument why the four color theorem holds on the first page of HN in at most a month. :-D
But the point is that pre-AI it was already the case that famous results were published that very few could understand or digest. I think it is reasonable to expect that we will soon be at a point that Lean says a theorem is correct but no human can or will ever understand the proof.
What if Lean verifies Mochizuki’s proof of the ABC conjecture. Do we disregard it becuase no other mathematician understands the proof?
I am probably being too optimistic, but wouldn't it solve the problem if peer-review had a pre-screening phase where you give a presentation about your work? Similarly to how a PhD presentation is given. It could give back the publishing power to the expert, rather than the journals.
Once you have validated that the knowledge you want to publish is yours and that you actually understand and own the work, then it doesn't matter if the paper is written by a LLM or if the LLM assisted you in doing the work.
For many of the rest of us, mere consumers of mathematical results, it’s sufficient to know that a^2 + b^2 = c^2 was proven by somebody or some machine at some point.
It would work better as a bar for hiring, rather than as a bar for publishing.

We'll end up with incomprehensible math because comprehensibility isn't rewarded. No one is going to get a Fields Medal, or tenure, for digesting someone else's results.
The incentive will be to be able to publish in a top tier journal. I suspect what Tao is advocating for is having journals reject such manuscripts.
> No one is going to get a Fields Medal, or tenure, for digesting someone else's results.
I'm sure no one gets a Field's Medal if others can't digest their results.
He says it shouldn't be able to published if they can't explain it. Publishing it is the reward.
Edit: I just saw Tao actually mentions the above essay in his paper.
He's a typical person otherwise, politically aware of how he barters for food; until proven otherwise this can be seen as little more than social moat defense.
To paraphrase a quote attributed to Upton Sinclair; hard to get a worker to understand something when their paycheck relies on them not understanding it.
The only interesting thing here is the frogs high up admitting they feel the heat.
(I don't know why you're so butthurt BTW - neigher of your ad-hominem comments actually outline your concern)
It's mostly memorization and recall and a single proof about primes he is well known for. It's akin to being well versed in Star Wars canon.
If Tao can be replaced by a model he isn't that smart just hyper-optimized in a narrow scope. As a scientist such evidence has to be a part of the assessment; it's not hard; find gaps in a syntax system and generate meaningful syntax to close the gaps. It's an idea printed in information theory books almost a century old.
He's well versed in existing content but has broken no interesting new ground. Where is his calculus or linear algebra. That to me is the real bar; definition of truly never before seen axioms and proof of them.
Lewis Hamilton is a great car driver but he didn't invent the internal combustion engine or racing; he's just a butt in a seat.
Butt hurt; because I don't easily accept awards handed out by innumerates who, not being mathematicians themselves, cannot possibly have an informed opinion on the quality of his work.
Many a mathematician and physicist out there have claimed there's no telling how much of this is verified; there are endless papers out there that constrain what we can actually know via scientific inquiry. Everyone in research just pretends they know it all because hey it's a living made not working in the mines.
But my bad for discussing and debating this all with experts over the years and not just accepting the populist take. If going with popular thing is the expectation Christianity is way more popular around the globe; lets just bin this science thing.
Good for Tao for achieving celebrity in a world of willfully ignorant people; convincing people too ignorant to challenge him to just give him awards sure means those awards are meritorious.
I simply don't carry water for and deify individuals when everything is clearly due to a mesh web of human labor across the globe.
It should be ignored and refused.
Science,at its core, does not care about the credentials or institutions. It cares about the results and to what extend they can be falsified.
This feel a bit like "we know all about physics, we can only get more precise" - moment
