I don't think this is a valid counterpoint at all. Math is cooperative, and comprehension is the point: the proof has value exactly because (and only to that extent) it empowers humans to understand an abstract truth. Chess is competitive: the memorized line has value because it makes you incrementally more likely to defeat your opponent.
reply
Math is also useful. If someone showed that p = np tomorrow in a formally verified proof I don't care if no one can understand it.

If a magic oracle tells you p=np, that's useless. How would that change anything?
reply
I would hope the magic oracle would continue to tell me ways in which I can use this knowledge practically.
reply
If it’s an oracle and we know it’s an oracle then it’s not useless. Humans make mistake and there are examples of published results that were widely believed to be correct by experts that later proved to be wrong. Why do you think human verified proofs are better than machine verified proofs?

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.

reply
I asked how would it change anything. What's the next step if an oracle were to tell you p=np that changes anything about the world?

We all believe it. It's a magic oracle. Now what?

reply
If it is known that A is provably true then one can study the consequences of A being true. It changes things becuase the body of knowledge has expanded.
reply
> If it is known that A is provably true then one can study the consequences of A being true

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.

reply
In this case won't this oracle also tell you what is the consequences as soon as it tells you RH is true and also much more? At this point what is the point of you knowing what is true and what is not?
reply
> It would be very useful to have an oracle tells us whether or not RH is correct.

For what? Which product becomes better if it is correct?

You have an unfortunate view of the value of knowledge. The frontiers of science would be static if everyone believed as you do.
reply
Someone claimed it would be "useful", without saying what for. Hence the questions "what for?". To try to shame people for that question in the name of science of all things is wild.
reply
The whole point why anyone cares about these proofs is that the things we learn as we make the proof might add value, proving p = np itself isn't interesting, that knowledge has no application and therefore no value in itself.

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.

reply
You are wrong as far as most mathematicians believe. The fact is important. The proof of the fundamental theorem of algebra is interesting and important but the theorem itself is also important.

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.

I thought the point of publishing was a matter of dissemination, to make available for people to then try to understand it? This is like saying, I don’t like music, so I’m going to tear down the venue. Then, all music genres suffer as a result, and all of society does, too. This idea is no good.

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?

reply
Oh it would change a lot. It would be an enormous psychological boost for everyone to find a practical algorithm.

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.)

reply
> a practical, albeit incomprehensible, algorithm for solving NP complete problems.

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.

A proof by contradiction that p = np is of no use to anyone, given that it wouldn't help you find any polynomial time algorithms for np-hard problems.

I don't think a proof that P = or ≠ NP would give you any polynomial-time algos for arbitrary problems either.
reply
I don’t recall anything specific off the top of my head but I am confident that such a proof would have immediate actionable implications.

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

reply
Abstract polynomial algorithms are of no use either, eg, translation may require galactic constants or high powers that are still intractable.

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.

reply
A proof that they are the same is of no use either, since it too wouldn't help you find algorithms that are faster.

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.

How would the mere knowledge that it holds, without any understanding why, be useful?

p = np doesn't produce any value though, the stuff you learn solving it might but the fact that they are the same wouldn't be valuable at all.
reply
sure, agreed, but once you have a proof, you can probably get AI to reduce other problems to that problem in P.
reply
Well then, just tell the AI that the statement is true and it will find reductions!

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.

reply
Why wouldn't you be able to do that without a proof? I don't see the value of the proof here, just ask the AI to solve the problem you want and the proof isn't needed.
reply
Why would it not be able to find reductions now, but be able to find them just by being told that P=NP is definitely true?
reply
From my understanding, the two are equivalent; if you can reduce an NP problem to a P problem, you've proven P=NP. The rest is application.
reply
Yes but it's also possible that there are other proofs. The point remains, the content of the proof is what matters, not that the statement is proven.

Math that humans don't understand but nonetheless allows AI systems to develop breakthroughs in various fields of science, technology, physics, engineering, medicine, etc., would have great value to humanity even if it doesn't help humans understand abstract truth at all.

reply
But at that point you have full AGI and its not just today's models. Today's models still need humans to understand things since it builds upon human knowledge.

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.

reply
It's reasonable to say that current or near future AI can find novel mathematical results and develop applications from those.

The idea of AI stepping from a graph theory/combinatorics innovation to some new and useful algorithm isn't crazy.

I hope I'm remembering this right: a mathematician claims to have a proof for the ABC conjecture, but can't conceive any other mathematician it's right — it's "too weird", so the proof is rejected?
reply
The consensus is that proof is in fact incorrect. People tried really hard (like putting in a year of effort) and most converged to the same place, that proof of 3.12 is incorrect or has a gap. Peter Scholze (who won Fields Medal) and Jakob Stix did a writeup. People seem to think Shinichi Mochizuki correctly reduced ABC conjecture to 3.12, but didn't prove 3.12, and also are doubtful about the whole program because 3.12 doesn't seem any easier than ABC conjecture while complicating everything.

Not quite? It is more that 1) someone has gone through it, identified a step he thinks isn’t a valid step, and the author hasn’t been willing to work with that person 2) most consider the proof, due to its length combined with those doubts as to its validity, not worth their time and effort to work through and understand (because it would take a lot of time, and they have jobs to do, doing research and teaching, etc.)

By this point, he is very much nutso enough that a Lean certified counterexample to his theories would not dissuade him. His response would be either that the formalization is incorrect (with no coherent insights on how to fix it), or worse, Lean itself is a tool of Western imperialism and incapable of properly explicating his ideas. He has, in the past, ranted against such things as monotheism and English grammar as being the reason for his theories' lack of popularity.

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.

Math isn't "cooperative". Math is about truths. The length of circumference. The area of a triangle. The formulas for these are true in an objective sense irrespective of whether you understand them.

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.

reply
First of all, mathematics is about so much more than the area of a triangle etc. that any analogy based on such simple things is overwhelmingly likely to be too simple to be of value.

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.

reply
> 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?

reply
No, they're saying that what is true in mathematics is contingent, not absolute. It all depends on which set of axioms use, what assumptions you make.

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.

reply
Sure, but just that some random statement is true isn't interesting. It's interesting if it helps understand some abstract structure better.
reply
It could also be interesting by having a practical use.
reply
Math is not about truths, at least not by the meaning of "truth" as a word in daily use.

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.

reply
The tastes and interests, and cultural pretext, of human beings are not arbitrary just because they’re not easily described.
reply
Yes and therefore?

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.

reply
This hasn't been a remotely reasonable characterization of math since at least Hilbert's time.
reply
I think Hardy would be very much on the same page with me, as well as Godel and many others. Mathematical truths exist independently from our feelings and processes to discover them. People do and should argue about which truths are interesting to pursue and refine, but all of them are out there to be discovered... or not.

Whatever philosophy you prefer, math is about establishing objectively valid logical results, completely independent of the human process used to arrive at them.

reply
Axioms don't exist independently from our feelings and processes, we pick axioms we feel are good, and axioms defines mathematics.

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.

reply
Is formal (aka "mathematical") logic part of mathematics? Now that's a philosophical question.

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.

reply
this is primitive understanding of math. what does "truth" mean here? usually arguing over definitions is something i hate, but that's the whole point of mathematics.

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.

This is a theme in Blindsight by Peter Watts as well.

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.

reply
What's amusing to me in this context is, summarizing emails and such has for a while been a supposed use case for AI—the LLM serving as the "synthesist" to explain long texts accessibly. But with this math question, a human "synthesist" would be needed to approximately understand the math discovered and programmatically verified by the LLM. So the roles reverse.

reply
Lean does have libraries, but since they are also in lean they are subject to the same rules. It's basically a super strong type checker. If it compiles the proof is valid. Unless there is a bug in the type checker.
reply
Why should you trust that the relatively small core of Lean is correct?

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.

Yes, you still need to be careful, especially if you have reason to think that the proof was from a malicious actor.
