> We (humans) should help humanity flourish. I understand that not everyone agrees. I have been called a “speciesist” for being “too human-centric”.

this is insane. the "speciesist" people aside (the best way for all other species to flourish is for humans to eradicate themselves right now, which is completely mad), i have the opposite problem: the _axiom_ seems to be: we should help ME flourish. "Me" as in people who are raking in trillions for their own very special selves right now, at the cost of everyone else's future, while none of them can be trusted to hold my cell phone for a second.

> if an industry commits to the axiom of helping humanity flourish

where does he see such industries, outside of maybe nonprofits?

That wouldn't do much for rice, pigs, chickens, or rats.

I don't think there are actually any "speciesist people." I think most, if not all, are the selfish "me people," who have disingenuously created "speciesism" by mad-libbing racism and sexism in a ham-handed attempt deflect criticism/opposition to whatever they want to do. Most of them aren't even "raking in trillions," they just don't like thinking about others or being told "no."

weird bias by authority aside, do you really think that the daily decisions in this world today, and anytime soon, will be made based on the "let humanity flourish axiom"?

I consider myself an applied mathematician though technically I’m an economist (macro models, mostly) and operations researcher and differential game theorist (odd combination, but whatever). For context I’m 45 and I’ve spent most of my working life in corporate life.

I’ve always been at a disadvantage academically because I’m rather clumsy with my manipulations, derivations, and I’m a disaster at mental arithmetic. I’m also dyslexic. But starting in the late 1990s when I was in High School I started to become fluent with CAS (Computer Algebra Systems): first Derive, then the Symbolics capabilities of Mathlab, and ultimately Mathematica.

The whole transition is turning out quite well for me: I’m now able to delegate exploring my intuitions to increasingly powerful tools, I no longer have to haul the pyramid blocks up the ramp myself but I can drop them in by helicopter (as if were) and what I bring to the party is intuition and understanding.

I view it a bit like astronomy: in ancient times, before telescopes, keen eyesight was a prerequisite to be an astronomer. Later, after telescopes, anybody with eyesight had enormously enhanced capabilities of observation, and now, with radioastronomy and other forms of remote sensing (neutrino observatories, gravitational interferometers) the whole field has opened up to people who by virtue of being blind would’ve literally been excluded only a few decades ago.

Go forth and multiply: everybody can become a mathematician now. There’s an infinite number of potential universes out there with an infinite number of facts to prove and disprove. And while we’re at it: there’s so much more to mathematics than conjectures, proofs and counterexamples. Solve, model, approximate, fiddle around: as long as you’re not doing trite numerics on arbitrary systems of equations you’ve cooked up for your own amusement you’re good in my books.

Enjoy the tools. Keep your wits about you. Work through the steps that are presented to you. Build your intuition. HAVE FUN.

Hauling the pyramid blocks is what gives people intuition and understanding. It is true that school systems usually have way too much computation -- it is easier to test and grade computation. But the only way that you were able to use computer algebra systems fluently is because you had internalized how algebra worked by hand. If we tell students that they no longer need to learn how to solve equations we are seriously depriving them of a mathematical education.

SamuelAdams10 days ago
Maybe. As a parallel, I know C# and F#. They are programming languages. They are built on top of Microsoft products like the JIT and more basically Assembly language.

I have no idea how assembly works - in my years of experience I’ve never had an issue that required I dig that deep into it. Does that mean I can’t be effective with higher-level tooling because I do not know the absolute basics?

keeda10 days ago
While true that doing things the hard way is critical to learn a discipline, the OP’s point is about what is possible with AI once you’ve built those skills and intuition. I think in the future it will be common for those passionate about a discipline to strategically avoid AI until they’ve “built the muscles.”

This might be clumsy but I will say it anyway. If music is math, how do you explain people who have innate musical abilities without formal academic training in notation, music theory, circle of fifths, etc.
piker10 days ago
Also there is some instinctual understanding of the work moving a big heavy rock takes, and how to do it. No such corollary for algebra and hence some civilizations never discovered or understood it.
Archer662110 days ago
I think the astronomy and telescope comparison is missing some nuance. You don't delegate actual thought to a telescope, the thinking and acting on the observations you make with it is still done by you. With AI that is different; you get the opportunity to delegate a lot of thinking and acting to it (practically all of it if you really wish), at which point it becomes dubious to call yourself the creator or inventor of some idea.

You can use AI like a telescope, and alleviate your inherent organizational problems or other ailments, which in my opinion is a great use case, as it is empowering. But there will also be plenty of people who are not looking to alleviate any mental/physical quirks they have to do more, but simply want to make a "quick buck" for the least possible effort from the work and thinking of others, without adding much value of their own. Lowering the bar makes things easier for both, the ones who bring value and the ones who merely exploit in some context.

Absolutely true: there’ll be folks who understand no mathematics at all and who will try to elbow their way in. There will also be (extending the metaphor) an ecology of instrument-makers and lens-grinders who somehow become party to the debate. But to be Frank (though I am James) mathematicians will recognise their own.

After looking at the title for a day, the idea occured that, without mathematicians doing mathematics, those people would end up in banking, so seeing the top post is most amusing. One of my local contacts is a semi retired bankster, who I am going to prank by pretending that theres something stuck in her fangs, looks like the still quivering flesh of a young accounts executive, which seems to be the thing that happens to mathematicians, money that is, triggers some sort of primitive predetory instinct better left dormant.

Everyone involved in AI should have read The Library of Babel [1].

It's about many things, but perhaps the most relevant idea here is that no information matters without understanding. We could generate all possible knowledge, but unless someone--a human--can verify and understand it, it doesn't count. The cure for mortality could be written on the moon, but if no one reads it, it hasn't really been discovered.

One counter-point: Humans have not figured out how general anesthesia works, but we use it every day to great effect.

mettamage10 days ago
The part that does count is that we can verify that we does what we want it to do. We just don't know how.

Same with the black box part of AI. What the weights represent? Arcane dark magic if you ask me. What do they do? Well with LLMs we're all experiencing it.

We have just convinced ourselves it is statistically safe, much like most of medicine. Most drugs are not made from molecular simulation of an entire human body.

Of course we have also convinced ourselves before that cocaine in drinks, lead in petrol, asbestos in walls… were all safe…

This reminds me of the Feynman interview where the interviewer asks "how do magnets work" and he goes on this rant of how that's unanswerable and you have to decide on what is it you really want to ask. You can't expect to know the full chain of knowledge because at some point you will be asking about quarks and gluons and then hit a wall where "nobody knows". Similarly you cannot simply just give up any investigation at all because then you'll end up recommending people to put lead in their cars.

Seems a bit nitpicky, we certainly understand how to use it with great effect, we just don't understand the biochemical mechanism.
thomasfromcdnjs11 days ago
While I get the point and it's true.

I'm a little more flexible, if the new knowledge (that human's don't understand) can be put into a mechanism and have an observable effect, I'd be happy enough. e.g. a new type of rocket fuel that burns 1000x more efficiently.

matheusmoreira10 days ago
Doubt.

If I vibecode a video game and manage to sell it on Steam, the information definitely mattered even though I didn't understand any of it.

There are drugs that nobody truly understands how they work and they are being used by professionals in actual treatments literally right now. We know purely statistical facts like "if drug X is used for condition Y it will help Z% of patients" and can only speculate as to their mechanism of action. They are used anyway and still benefit a lot of people.

undersuit10 days ago
Yeah that information mattered when someone wrote it down, not when the LLM regurgitated an approximation.

Why though a human? Mathematical proofs are very ivory-towery, but if OpenAI would solve a subkind of Cancer, without mortal humans understanding, cancer is still be healed.

sfn4210 days ago
Not unless humans were able to produce the medicine or perform the surgery or whatever is necessary to actually heal someone. In order for that to happen it has to be verified and understood by humans, like the other commenter said.
somenameforme10 days ago
I don't think this necessarily follows. The point of the Library of Babel is more one of permutations/combinatorics than of knowledge accumulation itself. In 'our' Library of Babel, each book would be informative, if not perhaps flawed in some ways. That's quite different from one in which in which the number of books that contain anything coherent whatsoever cleanly rounds to zero.

People keep talking about this like there's a finite amount of math to be done, and then the party's over. But that's never how math has worked, is it? Every problem you solve, ten new ones open up. Like a fractal, the more you zoom in, the more detail emerges. No matter how much better AI is at solving problems, it's not going to generate the "final, complete compendium of mathematics" that that seems to hover over this post.

Math is meaningful because ... some people like to do it. The same as any other human pursuit. It doesn't need a reason beyond that. And AI won't change that. There will continue to be things to explore, things to find out, things that are maybe just at the edge of AI's reach and needs a human to decide whether it's worth continuing to explore or not. (Remember, AI isn't free).

So, IDK, I think for people who enjoy exploring math, there will always be interesting areas to explore. AI just gives us a better flashlight.

BTW I do agree that there's going to be an incident soon, whether intentional, accidental, or paperclip-factory, that leads governments around the world to shut all this down for some time, perhaps even shutting off access to GPUs entirely. It seems unavoidable. But that's just a temporary respite and skirts the core philosophical premise of the post.

I guess Terence's main point has been all the time that if we let AI solve all these existing problems, we don't notice the new ones and then there is stagnation.

The universe is bounded by rules, as far as we can tell, and not a lot of them

Respectfully, this is not a useful frame for the discussion. Nobody is expecting to reach the limit you have noted either with or without the assistance of LLMs. So there is always more math that could be done.

That's physics. Not all math is physics.

If you study the history of math you’ll find that the interest in certain problems changes based on culture and technology.

In our lifetimes computers have made a lot of combinatorial and graph questions meaningful that otherwise would not be interesting.

itishappy11 days ago
It seems likely that there are an infinite number of math problems but only a finite number of interesting ones.
n4r911 days ago
Trivially false. Let P be the set of maths problems and I be the interesting subset of P. If I is finite, then there exists an element x belonging to P\I whose description is minimal among P\I. Then x is interesting. QED.
tim33310 days ago
Interesting is a bit in the eye of the beholder. Some people probably find maths boring full stop, some probably find all of it interesting.
captainbland11 days ago
I think it really depends on what the universe looks like as you drill down into it. It seems like the further down into smaller systems you get, the more analytically complex it gets. And then there will always be more value in enhancing the generalisations you have.

> Similar logic applies to every industry and every job. And it comes to the conclusion that we won’t have enough people for all the jobs that need to be done.

In the (extremely) short run, yes. In the long run, those jobs will also be done by AI.

It's like chimpanzees seeing human society and saying "look how complex it is, imagine how many chimpanzees it needs to maintain it".

Let's be honest: we don't know. Maybe you're right, but for the moment it's more likely that you're not. And countries cannot bet on that vague intuition at the cost of destroying their research communities and world leadership (which takes decades if not a century to achieve).

bananaflag11 days ago
I don't think research communities should be destroyed.

Best case, they still matter.

Worst case, AI kills us all and it's irrelevant that we "wasted" money on research.

Chimanzee vs Human is not an appropriate analogy. First, because they cannot communicate properly.

A better analogy: look at all these highly trained engineers, mathematicians, doctors, writers, philosophers, writers, scientists.

How many dumbass politicians do we need to keep it all running smoothly?

Turns out no matter how dumb politicians were, overall society has been developing positively over the history of mankind.

sm0rad11 days ago
Math proofs are special because they’re verifiable, safe, and do not require physical experiments. You can perform exhaustive parallel search in simulation with RLVR.

Do you think this applies to say, surgery, as well? There are few useful problems that share these properties.

Not all of it would translate, but robotic surgery could be done on anesthetized animals in a mass RLVR way.

A few people with way to much power are building AI to achieve their utopian, sci-fi dream. A few other powerful people are using that first group to achieve their post-democratic goals. It’s the most obvious top down attempt at imposing their vision onto the rest of the world. They aren’t building tools to serve anyone else than themselves
