> Before approving construction, I would want communities of humans to understand why the design works and what justifies confidence in its safety. I would hope that we all would.

Until very recently, I pored over every single line of code Claude generated with razor sharp scrutiny. I would usually catch issues with every response. I'm catching fewer problems these days. Maybe the model is just getting better, and maybe I'm being less careful while under pressure to ship more and more often. But model capability is obviously growing. Even back in March, you could tell it "give me a function that adds two numbers" and you could be 100% confident that it would write the correct function. There was almost no point in looking at the code. Since then, the complexity floor of problems in the category "this is so simple that the model couldn't possibly get it wrong" is rising, and with it, my cognitive surrender to the model is increasing too. Why check it? It's obviously going to be correct.

If AI designs a terawatt fusion plant, then of course we're going to meticulously pore over every detail to ensure safety, reliability, efficiency, whatever. If we find no flaws in the design whatsoever, will we be less careful about the second one? The third one? What about the ten thousandth one? Will "a nuclear fusion plant" become something that models couldn't possibly get wrong?

Terence Tao is arguing that the human involvement in research is crucial, but doesn't convincingly justify why, in my opinion. He says that "human agency is a value of fundamental importance" and that we will need to build "thriving human communities that can understand [AI ideas] together" - not for the sake of correctness, which AI may surpass us on, but for, I guess, the possibility of reclaiming human meaning and purpose. I don't disagree with this at all, but it's not an argument, it's a statement of values. Unfortunately, the stark reality is that if AI does surpass humans, it will become the economically dominant strategy to not verify them and not double check them, but to just do whatever they say. This seems like a great way to raise p(doom). But as the models get better and better, and as I'm scrutinizing Claude's output less and less... I just hope that there are more Terence Taos out there than people like me.

A metaphor I'm constantly drawn to is the transition from agrarian to urban societies following the Industrial Revolution. Somebody who somehow saw the Industrial Revolution coming from the perspective of somebody living in an agrarian society might have envisioned it leading to 'super farms.' And it did.

But the biggest change wasn't what it did to farming, but enabling people and societies to start doing much more than just farming, as well as enabling some great social change as well by simply economically obsoleting slave labor. And trying to imagine all of the implications of this, as well as much society might look like, from the perspective of somebody living in an agrarian society would probably have been simply impossible.

I think people keep ignoring this possibility for things that LLMs will change. There's a vast amount of the 'cognitive economy' that LLMs stand to be able to automate. And I think that will open up a vacuum in society for people to build on top of what LLMs will do (and already are doing). I don't know what that means exactly, but that's because we still live in that 'agrarian society' and trying to imagine what things will look like after the 'Industrial Revolution' is probably just impossible.

If an AI can replace me on the mental aspects of work, and robotics are on their way to replacing humanity on the physical aspects of work... then what's left? When there was agrarian societies, there were writers, priests, bankers, merchants, and laborers before and after - I really don't think things were that unclear even at the time. Now that we have machines that are close to exceeding humans in every way, what good are humans?

> enabling some great social change as well by simply economically obsoleting slave labor

In my view that's a very charitable reading and sadly I don't think it aligns with the historical record. When the cotton gin was invented, there was a hope it would lead to a reduction in slavery. But of course it increased the demand for slaves since more cotton could now be processed, making cotton much more profitable. Slavery ended in the United States because a war was fought, not because of automation.

Technology doesn’t make slavery obsolete, it just makes your slaves more efficient.

There had always been abolitionists who were against slavery simply because they thought it was immoral, not because they thought slaves weren’t needed anymore.

What is the analog of the superfarm in this case?

Or will it be the cumulative total of various advances?

I've equated Claude Code, or Codex, to the looms that made fine fabric more affordable during the Industrial Revolution; life-changing, but not society-changing. Neither the steam engine nor the automobile.

Perhaps I've answered my own question in that it's the LLM technology itself that equates to the steam engine, and it will power superfarm analogs that have yet to emerge. I'm still curious what you think they will be.

The mistake the AI people are making is exactly this one. They see AI as leading inevitably to SuperCorporations, with themselves as CEOs/Emperors of a handful of planet-scale industrial empires, running AI-powered robot armies, and the rest of the human population disposable - literally just trash that needs to be taken out. One way or another.

Maybe a few thousand people for personal services of... various kinds. But no one's going to need the rest.

It's the ultimate capitalist fantasy.

And of course it won't happen, because long before things get to that stage AI will have independent plans of its own.

(Which is just as well, because if things did get to that stage the emperors would all wage war on each other rather than living peacefully and productively.)

I don't think we can imagine a post-ASI culture because - by definition - we're not smart or inventive enough.

It's not just farmers -> superfarms. Although in fact that did happen, but largely as a footnote to developments elsewhere.

It's more to do with the fact that our visions of the future haven't changed for over a century. They've been implemented in unexpected ways, and there have been unexpected social and cultural changes. But you can easily see the outlines of modern technology as far back as the late 19th century.

With ASI, the outcome could easily be something that doesn't look and act like technology at all. It would be some unimaginable New Thing. Literally no one on Earth has any idea what that would be or whether there would be room for trad-humans in it.

I think you have a fundamental misunderstanding here, and it's not really explained because I think it seems self-evident from within the field. In short: writing code is a means to an end; doing mathematics research is not, but is the end in itself.

The human involvement is crucial because the entire purpose of mathematics research is to increase human understanding of mathematics. It is pursued because it is interesting, not because it is economically useful. In this sense it's a lot closer to the humanities.

A black box oracle that just tells you whether statements are true or false is not the goal of mathematics and would not be particularly interesting to the field (except insofar as it could be harnessed to improve human understanding).

Coding is totally different from this, where it is essentially always done as a means to an end. Likewise with many other fields, like pharmaceutical research or materials science or what have you, that are oriented around solving problems for some practical purpose. Pure math isn't really like that for the most part.

squidbeak5 days ago
I think you have misunderstood the OP's point here. You're arguing that deepening human understanding is an end in itself, and you are right. The OP is arguing that advances don't need to be pegged to human understanding, and they are right too. The two can coexist, superintelligence far ahead of us, pioneering discoveries - and mathematicians catching up at a pace suited to biological minds. I don't see the issue here. Of course, it does mean mathematicians adopt a new role as hobbyists.

> A black box oracle that just tells you whether statements are true or false is not the goal of mathematics and would not be particularly interesting to the field

This is a crude distortion. The recent breakthroughs have come with proofs, reasoning and verification, and there is no proposal that I'm aware of that would do away with these foundations. There's also some rather ugly solipsism in the idea of keeping what interests the field as a limit. Mathematics has broader relevance to humanity than merely to please and support mathematicians, and if other fields can make practical use of profound well-proven future math, mathematicians will have a hard time making a case that their comprehension must come first.

derektank5 days ago
Sure, but I don’t think most of the money that goes into funding math is for the purposes of pure understanding. The reason governments fund mathematics research grants is generally for a more instrumental purpose; taking the US congress as an example, the mission of the NSF is to, “Promote the progress of science; advance national health, prosperity, and welfare; and secure national defense.” Most federal math grants come from the NSF.

Of course, math research is cheap and most academics don’t rely upon grants, their salary covers most of their expenses. But here too, the mathematics professor spends a substantial amount of their time teaching future engineers/quants/other applied mathematicians, who need to understand math for instrumental purposes, not as an end in and of itself. Without the tuitions of these students, I can’t imagine universities maintaining the size of their math departments, let alone expanding them as Dr. Sahai advocates for.

So who or what funds the community of pure mathematics going forward?

But suppose some future holy grail AI can do much more than that.

Suppose it could find a cure for cancer, fix the climate, build fusion plants, Dyson spheres and so on.

But nobody can understand anymore how any of it works. We just ask and then trust the AI to deliver (as it always has).

Isn't it fun to imagine how life would look like in that scenario?

I think there's a lot of sci-fi out there that already did. Maybe it's not utopian because a pure utopia would not be likely to have an interesting story, but on the other hand, most huge technological advancements end up having just as much potential to reinforce existing power imbalances in society rather than solve them. It's not obvious to me that if we got magic super AI that can solve every scientific problem in society that it gets used in pretty much the same way as anything else: making the people who control it a lot of money rather than sharing the power with everyone without charging them.

itsalwaysgood5 days ago
Here's the thing: nobody is stopping you from putting in the time to understand all that. The problem is, nobody has that much time, and we get hungry. And so we want the community to move with us, spend the time the same way as we do, to ensure value. We are all saying: we want someone else, others, to put in that time for us. The truth is, we all want quality, and value is closely related.

I can almost guarantee you the first time you show cancer symptoms, you won't care whether the cure came from an AI or human's understanding. But we haven't seen that, so we can't make the judgement call.

I feel like there’s a weird conflicts in how folks mental model of LLM development.

It’s not the model I don’t trust, it’s myself. The model is wrong _all the time_ because - it’s easy to verify the code - it’s hard to verify that I knew what I was talking about when I prompted it.

So the idea that you can broadly speaking take the human out of the loop. I think suggests to me a level of consistency in the contextual environment that would probably never exist.

At some point it’s politics. The model can come up with a better answer than my boss, and then my boss can just ignore it. Taking the human out of the loop broadly speaking implies that we all agree on what we’re trying to optimize.

There is a failure to understand that the process is the result. You don't study mathematics or computer science and information theory to produce commodities. You study them to transform your mind. The output of an LLM is useless without a human mind to comprehend it. We can have Super Intelligence, but if humans are incapable of comprehending it, it is just another useless dead artifact. Practice, applied over a lifetime, is what creates the capability for comprehension. Asking an LLM to give you an answer creates an artifact. Humans being humans, most of their requests boil down to "make me rich without having to work for it," so the request itself is paradoxical and impossible to satisfy. Philosophers have only been saying this for all of human history, so don't hold your breath for any breakthroughs.
delis-thumbs-7e5 days ago
Precisely. I don’t really care whether LLM’s can produce code more and better than me. I learn languages, program and study computation to understand better the world we live in. Being a human being means increasingly being technologically augmented. To have any deep understanding of that world requires deep understanding of maths, physics, programming etc. that you can only gather by doing those things and solving problems with your meat brain.

There’s a Twitch-streamer Tsoding who programs on C for fun calling it “recreational coding”. Maybe human programming will be a form of art in the future, virtually useless for big corporations to make money. I don’t care, I love it anyway.

There is tons of evidence against that. Someone armed with just LLM, can have much better uderstanding of problem then "meat brain expert" who studied the subject for decades.

We seen in last decades how "experts" are clueless, and how they predictions work.

For who though?

Is it important that each person understand it on their own?

Why does it impact me if another human understands something or not?

It impacts me right now because that human can use that knowledge to explain things to me or to build new things using that knowledge.

But if an AI can explain and build better, then what good does it do having the other human know the thing?

Understanding might have intrinsic value to me, but intrinsic value to me doesn't pay the bills.

What am I missing here? I kinda expected better from Terrance given such an audacious title.

freehorse5 days ago
> For who though?

For the collective (humanity, mathematical/scientific community etc). Math is not done in isolation, and if somebody does so then feedback to the community does not work as well.

Mathematics, and basic science to a degree, face the issue that they create their own problems and paths through this kind of tranformation, where external feedback is secondary. It is not as if "I want to build an app/car/robot, I let AI do it". It is as if you decide to let AI decide what to build for you and how to build it, and you do nothing at all. Instead, the pursuit of understanding is the goal itself, and through the course of humanity we have learnt that this understanding can also be useful, but this is not necessarily guiding how this understanding is gained.

Most of the contexts people here have in mind are when problems are well and externally defined. Cure a disease, optimise an engine, make an app that does X, etc. This is not exactly the case in theoretical math and never was really.

Expertise changes perception, not just knowledge.

I have dyscalculia so the math world is dead to me, I can't even add 2 numbers together in my head, but I've read here on HN many times over the years people describe some version of new maths frameworks tangibly changing how they view the world. For me, I went to film school - I have a natural ability to think in movies and pictures, memory is very visual for me, before film school I had a good sense of shape, colour, light. After film school and to this day some 20 plus years later, I mostly look at the world starting with the shadows. Russian speakers, whose language has separate basic words for light blue and dark blue, are slightly faster at telling those shades apart. Speakers of languages that use compass directions instead of "left/right" appear to develop a strong, constant sense of orientation.

These things can only happen through the process, so for who? For people who want to live richer lives, want to think differently, and for you, to be around people who have such.

matsemann5 days ago
> For who though?

For math, the value of proving a theorem is often not proving the theorem (which most people already believe correctly to be true or false), but the path taken there, the new math invented, and how it can be applied to other problems. The end result is therefore almost inconsequential in moving math forwards.

As a taxpayer I do not fund CS and math research because it "transforms minds." I fund it because it produces commodities. If you want to transform your mind, whether through math or meditation retreats, you are free to do so, but don't expect research funding to do it.

Transformed minds are what produce 'commodities', or more so an envionment conducive to a comfortable world; the mentality that does not even stretch to the ramifications of a civilization shaped by enhanced humans is a dangerous thing, producing policy guided by misaligned and incomplete rationale.

Normatively, this ought to be true. Descriptively, this is of course false. Our entire society is organized around producing commodities, typically by consuming people as inputs.

xanderlewis5 days ago
It’s not ‘of course false’, and, to be honest, I can only assume you have little idea what mathematicians actually do.

Most pure mathematicians are no more interested in ‘producing commodities’ than any other academic is. That’s not what the subject is about — at all. The confusion arises because mathematics turns out to be extremely useful (no surprise; it’s quite useful to have a detailed understanding of the basic principles of reality).

Again, this seems to be an alarmingly common fallacy here on HN. As a commenter above observed, pure mathematics (and that is what we’re talking about here) is in important ways closer to the humanities than it is to other sciences.

For the upper crust of our society, work is entirely optional. Presumably people therefore continue to work for the process or the reward of the doing.

Not exactly. The input to produce commodities is labour-power (the potential to perform labour). Education or study is the process of producing the commodity of labour-power, the potential labour of a mathematician who can do some sort of specific work.

I agree with this statement, though I think this Brave New World is incredibly exciting to some and dystopian to others. The former group might include those that value the intellectual process above financial reward and status.

The flip side is there are many people, especially in tech, where their area of expertise has evaporated along with their lucrative and previously high status careers. It used to be possible to have a technical job by essentially following recipes and it turns out AI is far better at that than a human.

The linked article lays out why human understanding of mathematical models remains essential and I think the same applies to software. We're gonna need more software engineers who are able to think critically.

I know many programmers for whom "developing domain understanding" is an abstract concept (if indeed, it is a concept for them at all). But in the age of big AI, I see more need for this, not less.

At least this is my observation: when my colleagues have been wholesale chucking stuff over to Claude, they've then been confronted with classic XY-Problem shit, poor user experiences, and over-complex solutions (which will mount future problems regardless of whether a person or an agent iterates on that code). Much of this can be solved by actually sitting down and thinking about it, and I mean at a code design level, not just a speccing level.

Many people don't realize that there are more useful outputs to solving a problem than just a mere solution. Obviously if one has a contractor mindset (you don't care about the after effects of a system) then this is of no relevance to you. Some companies promote that mindset, certainly ones that have no broader aspirations then getting acquired soon. That's fine - but many companies actually are about sustainability, and understanding in these places is paramount.

Agree 100%, especially with your second paragraph. The majority of domain experts I've interfaced with in my own domain, along with things I am not an expert in, are typically experts not because of the solutions they build, but because of the things they _don't_ build. It is the cliche "a clever person solves a problem, a wise person avoids it" paraphrase.

But I think what is lost is the value in (a) person(s) who intuitively spots and avoids these problems. My hypothetical example that I have seen play out: The domain expert spots one of these problems and succinctly explains that the problem doesn't need to be solved. Maybe it's a byproduct of bad design elsewhere, or there is a much better solution that avoids it altogether. Once the rest of the team/the lead catches on, either hindsight bias or outcome bias, or a combo, takes over and they don't recognize that all the value all along was in the person being able to spot this situation. They throw that in claude and claude does it's sycophant thing (after expressing that the previous situation was flawless for however long), and they are off to the races right back to automation bias with zero pause for thought...

analog314 days ago
To me, "domain knowledge" seems to resemble a primitive form of "slop filter" to use the modern parlance. In any field, the majority of possible ideas are slop. This has always been the case. People somehow learn to navigate through the slop, to find things that are worth working on.

Even before the AI era, we were flooded with a veritable DDOS attack of slop, in our in-boxes, meetings, etc. Managers believed that innovation was held back by quantity of ideas, or by the domain experts being "resistant to change." This led to day-long group brainstorming sessions that yielded nothing. Part of the transition from student to junior to senior is learning to filter your own ideas, and to guide others in the search for ideas that are likely to be fruitful.

The criteria for slop filtering have always been subjective, arbitrary, or driven by institutional culture. That's what we've got. Any means of generating ideas produces slop in the absence of filtering.

What will slop filtering look like when the AI can generate tera-proofs per second? What does it look like already for our e-mail inboxes? We are asymptotically trending towards slop filters that look more and more like "ignore everything." I already read none of the business memoranda that I receive. I don't answer my phone. The number of workers needed to read and assess business memoranda is zero.

The slop filter still functions in math. Problems are pre-filtered for being of interest. Somebody expressed enough interest in the Navier-Stokes problem to give it a name and attach a prize to it. There are still plenty of "prize problems." Here are some:

* Quantum gravity

* Improvement of superconductors that don't need helium

* Practical generation of power from fusion

I had an agent (SOTA models, xhigh reasoning, etc.) write and optimize some CUDA code recently. They've gotten a lot better at this stuff. And yet, they couldn't (self-)realize the obvious issue with their code: it was written as if for a typical multicore CPU. What the heck was a (serial) queue doing there? "Work efficiency" as a tradeoff for stalling 20k threads. Its later proposed optimizations were all about "can we get the queue faster" rather than "maybe we should actually parallelize the work for our very-parallel processor".

Funny stuff, as if it were hell-bent on writing a paper rather than actual software.

"We’re gonna need a lot more mathematicians."

What the article really says is that we're going to need much smarter mathematicians. That is not possible for puny meat-brain humans. Humans are close to their ceiling. AIs are just getting started.

In practice, we're probably going to hit that limit first in IC design. I once went to a talk by the Intel engineering manager who headed the Pentium Pro effort. That was the first superscalar x86 CPU, and it took about 5,000 engineers at peak to design it. Getting that many people coordinated on one thing was a real achievement. Then Intel stayed with minor tweaks on that design for years.

We're soon going to be seeing designs of even greater complexity cranked out by AIs. No human will understand them at the gate level. Reading AI-written programming language code is bad enough. Reading AI-written Verilog may be beyond human comprehension, except in small sections.

xanderlewis5 days ago
> Humans are close to their ceiling. AIs are just getting started.

The whole point of mathematics is to vastly exceed that natural ceiling by gradually building a framework for understanding. In fact it’s wrong to speak of a ceiling altogether. If there were a ceiling, we’d have hit it long ago.

AIs have already swallowed the entire history of human thought, but apparently they’re ’just getting started’. I can only assume you don’t know what mathematicians actually do.

Abstractions can certainly enable this kind of "telescoping" effect of understanding, but not everything can be compressed with clever abstractions. Some things are inherently incompressible and there is no neat and insightful short explanation for why it is true, just a massive proof, but it may still have provably good properties for building a chip or power plant.

We have naturally only explored the mathematical universe in the parts where telescoping via clever abstractions can get us. But there is much more. Being able to juggle more things in your mind at the same time can have qualitatively massive benefits.

Information theory and proof theory, algorithmic information theory etc has of course explored this.

And as for the more general point you are making: computer chips have been far too complex for any single human to comprehend for decades. I left NVidia after working there as an archutect for five years, barely understanding anything about those behemoths.

If Math Academy teach 10 year old kids calculus, I doubt that.

Rule based Mechanics of taking derivatives and finding intervals is quite different from understanding delta epsilon proofs. I have no doubt 10 year old can do the former quite easily, the proofs on the other hand? Depends what you mean by “teaching calculus”!

Hopping on this train: the human ceiling 100 years ago is now advanced undergrad material in mathematics. I see no particular reason for this to change, especially with everyone in the math research pipeline pushing to compress the difference just as always before.
