Here’s one way to think about the difference between coming up with a formal proof and having something other mathematicians can use:
> A clear explanation can be found in Alex Kontorovich’s account of his own learning curve with formalized mathematics. In a nutshell: Mathlib, the dominant Lean library, is a human-curated formalization of an ever-growing fraction of existing human mathematics. It exposes clean APIs and abstractions, without which no autoformalization could take place. By contrast, Math Inc’s autoformalized proof of Viazovska’s results exposes no intelligible interface. Who in their right mind would merge a 200,000-line unaudited vibe-coded blob into the master branch of global human science?
Imo, the proved theorem is the API. And that's really all it has to be.
If there are other lemmas, etc buried inside that 200k blob that can be factored out and proved and used themselves, so much the better. But denying a machine-valid proof just because it's incomprehensible with what a human being considers a reasonable effort made to unpack it just seems odd to me. I see no reason not to accept the vibe coded blob if Lean says it's kosher except anthropocentrism.

You can't deny it if it's true, but the point is to find new techniques and abstractions. A proof you can't extrapolate and learn from is just a checkmark, and about as useful.

I couldn't disagree more.
A lot of mathematical "problems" are almost entirely pointless. Nobody genuinely cares about the moving sofa problem, or about square packing, or about the minimum number of colors needed to draw a map - it is the math that is developed during the solving process that is valuable!
An answer to a question like "what is the exact area of a unit circle" is a mere curiosity. Calculating a good-enough approximation is trivial, after all. But wanting an exact answer leads to developing calculus, which leads to most modern physics. Science was able to make a giant leap forwards due to the techniques developed, while the actual answer itself is mostly useless.

My instinct is to agree with you. I believe that the drive to a deeper understanding of the problems is what helps us unlock new areas of study, and find opportunities to transfer techniques or bridge otherwise unconnected domains.
But let’s consider a hypothetical: what if an intuitive understanding of the true “boundaries” of mathematics (if such things exist) is beyond the capabilities of a human mind? If there truly is no way to simplify some proofs down from 200,000 line incomprehensible gibberish to something you could teach to a high schooler or undergraduate or even a PhD. Is the proof still worthless? Sure, at the moment, it might be. Finding such a proof and understanding the implications of it are different skills, the latter of which AI almost certainly does not possess at the moment. But there may come a time where the AI can view the bigger picture and make the leaps you described (say, an eka-Calculus from an eka-unit-circle). These leaps may be as unintelligible to us as the proof in OP is.
I guess the question is: assuming that we can’t make the proof beautiful enough to spark deeper human understanding, do we still want it if it sparks deeper AI understanding?
Personally I would hate to live in a universe where the boundaries of science are beyond intuitive human understanding, but I think it’s almost certainly the case. The idea that the rules are all within our grasp reeks of anthropocentrism to me. I would love for the universe to prove me wrong though. It’d be a pleasant, hilarious coincidence if they do fit within the boundaries of our understanding.

"Mathematics isn't about proving the statement! It's about the collection of substatements which lead to the proof of the statement."
"Okay, so what determines what is and is not allowed in the collection?"
"Whether the given substatement is true or not, of course."
Like this is obviously silly, right. In your view you could have two guys both trying to prove or disprove that the area of the unit circle is 3, and yet only the guy doing it with some vision of nobility where he's building up to this grand theory of approximations is the one actually doing "real" mathematics. The guy who's doing it just because he thinks it's neat and would like an answer to the problem itself doesn't count, and you suspect he couldn't even exist.
program_whiz 39 minutes ago [-]
Isn't the question at hand whether its bad for mathematics if "prove the circle has area 3" devolves into 500 lines of inscrutable lean code, vs just having `pi r^2 == 3`? Sure they both "proved" it true/false, but knowing an answer isn't as useful as knowing why its an answer. Knowing an answer does have some value, its just not as valuable. If I can't work it out myself, I just trust the oracle.
Now if you ask "does the area of unit circle equal 4?", I don't really know, but we can go back to the oracle and ask again (we haven't learned the general pattern).
Also, I'm not sure that assuming this 'area of circle' question was cutting edge math, that the oracle wouldn't say 'yes, to a certain level of tolerance'. Can't count how many times I've seen agent decide a test needs to be loosened or deleted because its an "edge case" or "blocking". If you don't understand the proof you might get back 'yes' for some versions of 'is the area of unit circle 3' (depending on complexity of that ask).

New techniques and abstractions is how mathematics expand. Mathematics is about studying structures, proving statements is a part of it but it is not all what mathematics is about. If anything, proofs themselves are a means to an end (understanding). Eg Galois developed some techniques and abstractions to prove that there is no general solution to polynomial equations of degree >=5, but these techniques and abstractions gave rise to whole new mathematical fields.
Mathematics has to be also understood from the perspective of theory building, not just problem solving.
ben_w 2 hours ago [-]
> I see no reason not to accept the vibe coded blob if Lean says it's kosher except anthropocentrism.
The laws of mathematics exist and their truths hold before they are proven by humans or our machines, so in a very real sense the entire point of proving anything in the first place is anthropocentrism.
That, plus cleaning it up may reveal it contains proofs of other things we also want to know. Imagine if this happened to also contain as a sub-part a proof of all the open Millennium Prize Problems? We don't know until we investigate. (If it was a specific list of things to check from rather than expanding humanity's library, we could just ask an AI to do it for us… but as The Wachowski sisters wrote in their most famous script: "I say your civilization because as soon as we started thinking for you, it really became our civilization").

The theorem doesn't exist in a vacuum. It talks about objects that must be formally defined. And if that formal definition (which is part of the API) is not immediately compatible with those others use, and every single theorem comes with its own definitions of the objects they're working on, you're going to be reinventing the wheel over and over again.

Anyone who understands type theory and how theorem provers work? It's sort of akin to saying "how do you know that a massive C++ program that compiles to machine code compiled to the correct machine code that will actually run and it's just not a random string of bits!?!?!", you know because the compilation would have failed otherwise(this is different than saying the program behaves correctly, but that's precisely the difference between formal proofs and compiled programs).
The entire argument both you and Bessis are implying is that mathematics must be human intelligible. But there's absolutely no reason to assume that every mathematical statement must have a human intelligible representation. There is also not reason to assume that if we restrict ourselves to the subset of mathematical statements that are human intelligible that this is of any use.
Just because people who don't want this to be true, and I can understand the motivation, doesn't mean that it isn't still the case.

Hopefully the point is clear: A proof, even if it is correct, that is totally obscure and unintelligable by humans is not very useful for mathematics. It's a black box that doesn't further understanding of the structures and approaches to think about them, and that's what math is all about.Just having a big binary blob of a program doesn't help much if you want to add a feature.
That's also why biology is so hard. There is no source code. It's just millions and millions of years of evolution and things have evolved in weird ways that don't really make it easy to understand them, even though they clearly work.

Someday, human mathematicians might end up doing proofs for proofs.
When a codebase gets too large, you eventually can't understand all of it. Even code I wrote myself, I can't fully grasp it.
In those cases, we usually write tests.
But when tests get too big, we end up writing tests for the tests.
Eventually, it feels like we're heading into an era of proofs for proofs.
For me, this problem usually unfolds like this:
1.I can't trust SDKs or Stack Overflow code.
2.So I write tests.
3.But I can't trust the tests either.
4.So I use test coverage, mutation testing, property testing, and fuzzing.
5.If that's still not enough, I add formal verification.
6.And then the problem becomes: can I trust the verifier?
That's how it ends up. Wouldn't human work shift toward verifying the verification systems themselves?

Interactive theorem provers are what verifies (or proves) the proof here. This means you don’t even have to look at the actual proof to check its correctness. You just have to make sure the theorem definition is what you wanted (not to say this is trivial) and that no nonsense axioms were defined etc. Now for verifying the theorem prover itself, this is kind of a chicken and the egg problem. We know the mathematical foundations are solid. But to check the implementation of said foundations would require… another theorem prover. In practice, most theorem provers try to make their kernel as small as possible so it can be reasoned about by humans. Coming back to the original topic, mathematics isn’t all proofs though. Someone has to come up with new theories and models. I guess this is what mathematicians would be doing in the future if AI becomes better at proving things than humans. But I could see it narrowing the field, just like it’s doing in others.
mockerell 6 hours ago [-]
That’s an interesting way to think about it. While tests don’t satisfy mathematicians‘ standards for rigor one could instead look at interactive proofs from complexity theory. These are of interest if a problem doesn’t allow for short proofs, i.e. when the problem is not in NP [1].
In your scenario an adapted AI-assisted theorem prover would be the prover, and a mathematician the verifier.

What does that even mean? Sorry, this is just a nonsensical term.
The issue is not that the proofs could be wrong. It's that humans don't understand them even if they are verifibly correct.
In contrast, with software you don't know if it's correct. That's what you have a test for. Even if you understand it, there could be a bug. And tests could have bugs too, so you can have tests for tests. But proofs that are verified are correct. That's it.
Imagine you have a program that is formally proved to be correct. You don't need a test for it. However you might not understand it. Having a test or not does not change that.
TL;DR: Correctness and understandability are (mostly) independent properties.
bananaflag 7 minutes ago [-]
Thank you for spelling this in detail!
One thing I might add is that not all programs can be proved to be correct for the simple reason that not all purposes of a program can be mathematically specified. For example, for (even "closed world" domain programs like) a chess engine, the one thing that matters (in the absence of a complete solution of a game like there exists in checkers) is "can beat world champions", which can only be tested empirically. Or sometimes, e.g. business logic software, the purpose can be mathematically specified but not in a simpler way than the code itself.

The use of computers in mathematics has been somewhat controversial from the very start.
There are of course all the computer-assisted proofs (see 4 color theorem), as well as the partially-assisted ones (see Viazovska et al on packing problems in dimensions 8, 24). But even finding a solution numerically, then rigorously verifying its properties can leave a lingering sense of incompleteness, of a gap in understanding.

Just that the set of proofs a human can interpret and the set of statements a human can understand overlap; conversely, you require that the statements/theorems humans can understand be a larger class than the proofs they can understand.

- can we only understand theorems for which we comprehend their proof?
- or can we understand theorems despite not comprehending the proof structure?
Within the mathematics community, opinions differ. But you’re elevating your perspective on that question into a law, without any evidence.

> understand theorems for which we comprehend
I don't know what your distinction between "understand" and "comprehend" but my point was not about these words, but about being "useful" and being "understandable".
I'm saying there's no relationship between a mathematical statement being useful and it being understandable.
If it is true that "understanding is a prerequisite for usefulness" (where "understanding" means that a statement can be proven in a way that is intelligible to humans) was a property of mathematical expressions, then this fact would certainly be useful (we could exclude any statements that no human understand from the world of useful mathematical expression). But, by that definition, we would need to understand that statement, so you would need to be able to prove that "understanding is a prerequisite for usefulness" in a human intelligible way.
Now what I just wrote is in itself not a proof that we can't know, but proving the above statement would involve expressing the claim in a mathematically verifiable way that was also understandable by humans, which does imply something remarkable about human cognition (something that would be intelligible no less!)

Mathematics has always been an experimental science to some extent. While Newton, Euler and Gauss would spend a lot time calculating numerical approximations by hand, modern mathematicians have been doing the same using computers and software. And once an a clear picture emerge about what’s going, you can start to formalize that and attempt to prove and communicate your results in the standard definition, proposition, lemma,
theorem scheme. (Btw there is even a journal called Experimental Mathematics devoted to this approach).
I don’t see that LLMs will fundamentally change this,
but rather accelerate the speed

Well, if you can formalise the problem statement (this is the hard part) sufficiently well that the computer can produce a proof, you can be very sure the proof is sound.
A fundamental property of any formal proof is that it can be checked by a fairly stupid machine, automatically, because every step is a simple mechanical operation that names one of a handful of axioms and refers to a handful of earlier steps, the truth of which has already been established. So while coming up with a proof may require genius-level thinking, checking an existing fully fleshed out proof is simple -- just potentially very tedious because of the sheer number of steps.
That said, a typical human-written proof omits many steps considered "obvious" to a trained mathematician. Converting this to a formal proof involves interpreting what the original author "must have meant", which requires a lot of expertise and can go wrong -- or it may reveal that there is some inconsistency in the original claim itself.

How does this involve computer checking of a formal proof?
Last time I checked, it was a disagreement over whether an informal proof is sound, which is exactly the problem with informal proofs.
ETA: There might be a misunderstanding about what "formal proof" means. Even a very detailed, precise English-language description of a proof is generally not a formal proof. The bar is essentially: "It could be checked by a machine that follows simple rules." If different interpretations of a "proof" are possible, the "proof" is by definition informal. Informal proofs are valuable because they are strong evidence that there's a corresponding formal proof "underneath" that would establish the theorem's truth, and because they are (usually) much easier to understand.

I wonder if mathematics as a science field moves more into engineering or if a different branch will emerge that is closer to that because to the point of the article, science is about understanding not just results.

To assume that the universe is disorderly presumes knowing some esoteric objective truth about how the universe works. Since the field of natural sciences does not provide that truth (by design), and practices that do aim to provide that truth (metaphysics, religion, etc.) seem to have different versions of it, I would say that there’s a fair chance that the universe is not that disorderly and we just lack better models for describing it.

If mathematics is human understanding of logical consequences, understanding is the priority. But if AI proves something we can't understand but can utilize, that is a different sort of useful.

I don’t know about “close”,
but there are certainly results in math that are considered deep because they require the use of a “Hard Theorem” at some point. That kind of building on top of something Very Difficult is still possible without understanding the “Very Difficult” part. I’d say a lot of not-amazing math is built by believing the platform works but not being able to built it yourself.
I couldn’t build an internal combustion engine or even a plastic box, so maybe there’s nothing wrong with this approach.

Yes the "truth" (doesn't exist, see Gödels theorem) is discovered in a vast, wild landscape that Mathematicians explore.
But which areas are worth exploring is a critical question. Partly driven by application, partly aesthetic. It's a quest for simple things that are a bit surprising, or that were hard to make the statements so simple.

It's amazing how much attention this issue has gotten. What is lost in the hype is no AI can tell you if a proof is correct. An AI can produce a convincing looking proof, but it can have a subtle but critical error or make an assumption that is unfounded. Thus, it ultimately comes down to humans. A mathematician has to craft the prompt, and mathematician to interpret/check the results. Also, these programs are very expensive and propitiatory. They are not like the commercial AI that regular people use. It takes considerable prompting and trial an error to solve even Olympiad/Putnam problems, and tons of work by humans pouring over the results to see if it's correct. For every Erdos problem that captures the headlines, there are many where it failed or untold hours of prompting and token burn to get that result, and manhours verify it.

> A clear explanation can be found in Alex Kontorovich’s account of his own learning curve with formalized mathematics. In a nutshell: Mathlib, the dominant Lean library, is a human-curated formalization of an ever-growing fraction of existing human mathematics. It exposes clean APIs and abstractions, without which no autoformalization could take place. By contrast, Math Inc’s autoformalized proof of Viazovska’s results exposes no intelligible interface. Who in their right mind would merge a 200,000-line unaudited vibe-coded blob into the master branch of global human science?
https://davidbessis.substack.com/p/the-fall-of-the-theorem-e...
If there are other lemmas, etc buried inside that 200k blob that can be factored out and proved and used themselves, so much the better. But denying a machine-valid proof just because it's incomprehensible with what a human being considers a reasonable effort made to unpack it just seems odd to me. I see no reason not to accept the vibe coded blob if Lean says it's kosher except anthropocentrism.
As far as I can tell from colleagues in other domains, it’s the same there. One paper will mention something off-hand and that’ll cause someone else to have a spark of insight, which turns into it’s own valuable research
I couldn't disagree more.
A lot of mathematical "problems" are almost entirely pointless. Nobody genuinely cares about the moving sofa problem, or about square packing, or about the minimum number of colors needed to draw a map - it is the math that is developed during the solving process that is valuable!
An answer to a question like "what is the exact area of a unit circle" is a mere curiosity. Calculating a good-enough approximation is trivial, after all. But wanting an exact answer leads to developing calculus, which leads to most modern physics. Science was able to make a giant leap forwards due to the techniques developed, while the actual answer itself is mostly useless.
But let’s consider a hypothetical: what if an intuitive understanding of the true “boundaries” of mathematics (if such things exist) is beyond the capabilities of a human mind? If there truly is no way to simplify some proofs down from 200,000 line incomprehensible gibberish to something you could teach to a high schooler or undergraduate or even a PhD. Is the proof still worthless? Sure, at the moment, it might be. Finding such a proof and understanding the implications of it are different skills, the latter of which AI almost certainly does not possess at the moment. But there may come a time where the AI can view the bigger picture and make the leaps you described (say, an eka-Calculus from an eka-unit-circle). These leaps may be as unintelligible to us as the proof in OP is.
I guess the question is: assuming that we can’t make the proof beautiful enough to spark deeper human understanding, do we still want it if it sparks deeper AI understanding?
Personally I would hate to live in a universe where the boundaries of science are beyond intuitive human understanding, but I think it’s almost certainly the case. The idea that the rules are all within our grasp reeks of anthropocentrism to me. I would love for the universe to prove me wrong though. It’d be a pleasant, hilarious coincidence if they do fit within the boundaries of our understanding.
"Okay, so what determines what is and is not allowed in the collection?"
"Whether the given substatement is true or not, of course."
Like this is obviously silly, right. In your view you could have two guys both trying to prove or disprove that the area of the unit circle is 3, and yet only the guy doing it with some vision of nobility where he's building up to this grand theory of approximations is the one actually doing "real" mathematics. The guy who's doing it just because he thinks it's neat and would like an answer to the problem itself doesn't count, and you suspect he couldn't even exist.
Now if you ask "does the area of unit circle equal 4?", I don't really know, but we can go back to the oracle and ask again (we haven't learned the general pattern).
Also, I'm not sure that assuming this 'area of circle' question was cutting edge math, that the oracle wouldn't say 'yes, to a certain level of tolerance'. Can't count how many times I've seen agent decide a test needs to be loosened or deleted because its an "edge case" or "blocking". If you don't understand the proof you might get back 'yes' for some versions of 'is the area of unit circle 3' (depending on complexity of that ask).
Mathematics has to be also understood from the perspective of theory building, not just problem solving.
The laws of mathematics exist and their truths hold before they are proven by humans or our machines, so in a very real sense the entire point of proving anything in the first place is anthropocentrism.
That, plus cleaning it up may reveal it contains proofs of other things we also want to know. Imagine if this happened to also contain as a sub-part a proof of all the open Millennium Prize Problems? We don't know until we investigate. (If it was a specific list of things to check from rather than expanding humanity's library, we could just ask an AI to do it for us… but as The Wachowski sisters wrote in their most famous script: "I say your civilization because as soon as we started thinking for you, it really became our civilization").
Why not just fork the original master branch of human science to an ai-enhanced one and see where that brings us?
So yeah, generated machine-valid proof can be denied if it's incomprehensible, same as human machine-valid proof can be denied for same reasons.
just as we don't re-prove Fermat's little theorem every time I use it in a proof, because well, it's a theorem.
Replacing thought and curation with repeated automation is tech debt, pushed down to fundamental knowledge and understanding.
Here is a other one: hello_world.c versus hello_world.exe (apologies for windows extensions, just for illustration).
One is made by a human for human consumption and extension (though legible by a machine). The source code.
One is made by a machine for a machine. Unreadable by a human. The "binary", though that's a terrible misnomer. (Sure you can disassemble but any nontrivial program is too much to cope with as a whole).
Source vs binary. Both are useful but only one is useful for human consumption.
Anyone who understands type theory and how theorem provers work? It's sort of akin to saying "how do you know that a massive C++ program that compiles to machine code compiled to the correct machine code that will actually run and it's just not a random string of bits!?!?!", you know because the compilation would have failed otherwise(this is different than saying the program behaves correctly, but that's precisely the difference between formal proofs and compiled programs).
The entire argument both you and Bessis are implying is that mathematics must be human intelligible. But there's absolutely no reason to assume that every mathematical statement must have a human intelligible representation. There is also not reason to assume that if we restrict ourselves to the subset of mathematical statements that are human intelligible that this is of any use.
Just because people who don't want this to be true, and I can understand the motivation, doesn't mean that it isn't still the case.
Would we still be able to use computers? Of course! They don't need the source code to run.
Would we nevertheless be in big trouble? Oh definitely. We'd need to write all software again, from scratch. Some critical parts we could reverse engineer. Maybe even derive some structures that translate back into source code, but only because a human wrote that source code in the first place.
Hopefully the point is clear: A proof, even if it is correct, that is totally obscure and unintelligable by humans is not very useful for mathematics. It's a black box that doesn't further understanding of the structures and approaches to think about them, and that's what math is all about.Just having a big binary blob of a program doesn't help much if you want to add a feature.
That's also why biology is so hard. There is no source code. It's just millions and millions of years of evolution and things have evolved in weird ways that don't really make it easy to understand them, even though they clearly work.
It remains all of those things, sitting alone in its own repository of 200kLOC; what benefit comes from merging it into mathlib?
> There is also not reason to assume that if we restrict ourselves to the subset of mathematical statements that are human intelligible that this is of any use.
This is obviously silly:
Things that aren’t human intelligible aren’t human usable, so the restriction is necessary to have a collection of things humans can utilize.
This is objectively false, people use things every single day they don't understand. We still have plenty of things about the world we don't understand but still find useful.
You are saying anything we know to be the case, but cannot understand why cannot be used? Can we just stop sleeping because we haven't reasoned why sleep is necessary even though we know it is necessary? I mean we still don't really understand gravity (we know how but not why)
They approximately use them with varying degrees of success, but also mistakes, broken inferences, etc.
My exact point is that your view reduces our ability to do mathematics to that broken, flawed usage and thereby undermines its utility for logical precision: mathematics is only useful because we cleanly understand it.
When you try to use mathematics without understanding, you cause disasters: stock market crashes from mispricing options, Amazon’s 2018 hiring freeze from misallocating $1B, etc.
Note: neither of your examples (sleep, gravity) are things that people intentionally use. They just happen to people.
I think it’s very telling you couldn’t think of an example.
So what will you do if the doctor prescribes you an LLM-vibecoded drug that nobody understands how it works, yet it cures some deadly affliction with close to 100% efficacy?
What if, say, these incomprehensible math results lead to a revolution in quantum physics which unlocks chip topologies that are orders of magnitude faster than human comprehensible designs?
Would the high priestess of human reason pass her divining rod over such chips or life-saving drugs and reject it as the work of the AI devil?
The telco that manages loads and allocates networks knows how voice compression works.
The farmers and supermarkets know how the supply chain works.
None of your questions show why mathematics should include blobs of incomprehensible gloop, where no mathematician, no logician, no philosopher, no man on the street can make sense of said gloop, or use it in any way to further human knowledge.
When it's been decomposed down we can discuss this further, but now it's like saying red is red, just because.
I think it might be fair to say that a proof cannot be without value if it proves something meaningful to a human, that a human can use somehow? But such proof probably doesn’t belong in a library seemingly explicitly dedicated to human-graspable proofs. Just because it violates the intent.
It’s not like such proofs mustn’t exist at all.
Reasoning by analogy...
So why don;t they use AI to write Lean programs? That should make the AI-proofs more readily human undersrndable.
When a codebase gets too large, you eventually can't understand all of it. Even code I wrote myself, I can't fully grasp it.
In those cases, we usually write tests.
But when tests get too big, we end up writing tests for the tests.
Eventually, it feels like we're heading into an era of proofs for proofs.
For me, this problem usually unfolds like this:
1.I can't trust SDKs or Stack Overflow code.
2.So I write tests.
3.But I can't trust the tests either.
4.So I use test coverage, mutation testing, property testing, and fuzzing.
5.If that's still not enough, I add formal verification.
6.And then the problem becomes: can I trust the verifier?
That's how it ends up. Wouldn't human work shift toward verifying the verification systems themselves?
[1] https://en.wikipedia.org/wiki/Interactive_proof_system
What does that even mean? Sorry, this is just a nonsensical term.
The issue is not that the proofs could be wrong. It's that humans don't understand them even if they are verifibly correct.
In contrast, with software you don't know if it's correct. That's what you have a test for. Even if you understand it, there could be a bug. And tests could have bugs too, so you can have tests for tests. But proofs that are verified are correct. That's it.
Imagine you have a program that is formally proved to be correct. You don't need a test for it. However you might not understand it. Having a test or not does not change that.
TL;DR: Correctness and understandability are (mostly) independent properties.
One thing I might add is that not all programs can be proved to be correct for the simple reason that not all purposes of a program can be mathematically specified. For example, for (even "closed world" domain programs like) a chess engine, the one thing that matters (in the absence of a complete solution of a game like there exists in checkers) is "can beat world champions", which can only be tested empirically. Or sometimes, e.g. business logic software, the purpose can be mathematically specified but not in a simpler way than the code itself.
There are of course all the computer-assisted proofs (see 4 color theorem), as well as the partially-assisted ones (see Viazovska et al on packing problems in dimensions 8, 24). But even finding a solution numerically, then rigorously verifying its properties can leave a lingering sense of incompleteness, of a gap in understanding. I like this one quote by (allegedly) Wigner that illustrates it well:
"It is nice to know that the computer understands the problem, but I would like to understand the problem, too."
But a montage about weight lifting does not a body builder make.
But why should it be the case that this is always possible?
It's entirely reasonable that the set of useful mathematical proofs is a proper superset of human intelligible useful proofs.
In fact, to argue the contrary would imply there is something incredibly remarkable about human cognition.
If you can't explain something in a way that a child could understands it, you don't fully understand it either.
Just that the set of proofs a human can interpret and the set of statements a human can understand overlap; conversely, you require that the statements/theorems humans can understand be a larger class than the proofs they can understand.
To me, it’s not obvious which of those should be true:
- can we only understand theorems for which we comprehend their proof?
- or can we understand theorems despite not comprehending the proof structure?
Within the mathematics community, opinions differ. But you’re elevating your perspective on that question into a law, without any evidence.
I don't know what your distinction between "understand" and "comprehend" but my point was not about these words, but about being "useful" and being "understandable".
I'm saying there's no relationship between a mathematical statement being useful and it being understandable.
If it is true that "understanding is a prerequisite for usefulness" (where "understanding" means that a statement can be proven in a way that is intelligible to humans) was a property of mathematical expressions, then this fact would certainly be useful (we could exclude any statements that no human understand from the world of useful mathematical expression). But, by that definition, we would need to understand that statement, so you would need to be able to prove that "understanding is a prerequisite for usefulness" in a human intelligible way.
Now what I just wrote is in itself not a proof that we can't know, but proving the above statement would involve expressing the claim in a mathematically verifiable way that was also understandable by humans, which does imply something remarkable about human cognition (something that would be intelligible no less!)
I don’t see that LLMs will fundamentally change this, but rather accelerate the speed of mathematical research.
Some computer generated proofs might of course be hard to understand, but at least their existence gives another data point work with.
Doing Mathematics is more than proving something, that’s just the end of a long road spent pondering at one’s desk about how things could work out.
If you don’t understand the problem you can’t be sure that the computer does.
But I also definitely don't understand the problem if I can't get the computer to understand it, with tests.
In some sense I always considered programming to be more trustworthy than maths arguments without the certainty of a solver proof.
With all of these questions in the air, epistemology might be making a comeback.
Type theory can also be an independent synthetic foundation atop which you build mathematics.
I disagree, software engineering is a mature discipline now, and at this point we have so many testing frameworks (unit testing, syntax testing, regression testing, fuzzing, testing end to end, live, with a subset of known good and incorrect inputs, chaos monkeys, etc, etc, that to say "there's no way of verifying the AI-generated code" is frankly incorrect.
Or, if you insist, defend the "there's no way of verifying the code, at all", and not only AI-generated.
(if it helps I work in the company where before the code even starts being written, several extensive tests for it must be ready first. It's hard to even commit a broken code, and later in the pipeline it's very easy to catch the subtly broken or incorrect code)
A fundamental property of any formal proof is that it can be checked by a fairly stupid machine, automatically, because every step is a simple mechanical operation that names one of a handful of axioms and refers to a handful of earlier steps, the truth of which has already been established. So while coming up with a proof may require genius-level thinking, checking an existing fully fleshed out proof is simple -- just potentially very tedious because of the sheer number of steps.
That said, a typical human-written proof omits many steps considered "obvious" to a trained mathematician. Converting this to a formal proof involves interpreting what the original author "must have meant", which requires a lot of expertise and can go wrong -- or it may reveal that there is some inconsistency in the original claim itself.
The controversy around Mochizuki and the "abc Conjecture" proof is a contrary example.
Last time I checked, it was a disagreement over whether an informal proof is sound, which is exactly the problem with informal proofs.
ETA: There might be a misunderstanding about what "formal proof" means. Even a very detailed, precise English-language description of a proof is generally not a formal proof. The bar is essentially: "It could be checked by a machine that follows simple rules." If different interpretations of a "proof" are possible, the "proof" is by definition informal. Informal proofs are valuable because they are strong evidence that there's a corresponding formal proof "underneath" that would establish the theorem's truth, and because they are (usually) much easier to understand.

Perhaps a proof without understanding is just generating numbers.
