AI is solving open math problems faster than humans understand

1. Unit distance breakthrough — ▶ 7:34

   Erdős conjectured in 1946 that a square grid maximizes the number of unit-distance pairs among n points. OpenAI's system found a better arrangement using a fairly obscure corner of algebraic number theory. Aaronson's judgment: the techniques were unfamiliar to experts on the problem, but finding connections is much of human mathematics, and a human result would have earned tenure and an Annals of Mathematics paper. Commentary from Timothy Gowers and others made it hard for researchers to ignore, and his students were despondent. By summer's end, he says, papers routinely carried AI usage statements.

2. Why counterexamples fall first — ▶ 11:27

   Aaronson argues AI excels at problems that require trying thousands of strange constructions until one works. It never tires, and it is not discouraged when experts believe no such construction exists, which he says weighs heavily on humans. If a search stalls, a thousand more agents can run in parallel. He and the host cite Navier-Stokes, the Jacobian problem and unit distance as wins of this kind. The implication, an editorial inference, is that stamina and parallelism are cheap for machines and costly for people, so persistence-bound problems fall first.

3. Unique games and Lean — ▶ 12:40

   The unique games conjecture, posed in 2001, was central to hardness of approximation, and Aaronson's wife has worked on it for the entire time he has known her. OpenAI's solution, one of 372 open problems it published to a GitHub repository, comes with a Lean certificate, a mechanically checkable proof. Aaronson lists residual doubts: whether the statement was encoded correctly, past bugs in Lean, and the unknown soundness of the underlying logic. Even so, he says assurance is higher than for an unverified proof, even one nobody understands.

4. Correct but incomprehensible proofs — ▶ 16:12

   His wife spent weeks on the unique games proof, some dozens of pages, and described it as written by someone on psychedelics: key claims scattered, central ideas hidden. She concluded the only way in was to use AI. The core is a new error-correcting code. Aaronson thinks the models lack a good model of the human reader, knowing what an expert finds obvious, a flaw he says graduate students share. He expects years of work just digesting the GitHub dump, and expects companies to publish batches only for the biggest problems.

5. The teleportation machine — ▶ 22:02

   Aaronson offers an analogy for what the results do and do not deliver. AI is a teleportation machine that drops mathematicians atop mountains they were trying to climb. But what they cared about was the path up, so humans must now go back and find it. He has no doubt the results will advance human understanding, but says extracting the insight is currently left to people. The framing locates the remaining human contribution in explanation and mining of ideas, though the host immediately notes that every such role can be answered with a call for AI to do it better.

6. Two questions, one weak analogy — ▶ 23:17

   Aaronson separates two questions. Can humans forever contribute something AI cannot? He doubts anyone can be confident, given that claimed walls have been smashed and we are living in their wreckage; AI may soon explain proofs and propose better questions. Second, will we still want to do math? The chess analogy, where humans lost supremacy 30 years ago and the game thrived, is imperfect. The host objects that chess is combat while math is exploration. Aaronson concedes the point partly and adds a further unknown: whether society will keep supporting mathematicians.

7. Humans at the steering wheel — ▶ 26:49

   Aaronson tells students humans are needed urgently now, and the reason is alignment: no AIs are known to be reliably aligned with human values. Humans must stay at the steering wheel of civilization, evaluating outputs and judging whether a model is hallucinating or lying. That requires people who understand math, physics and programming even where AI now beats them. This is a protective argument rather than an intellectual one. As an editorial inference, it justifies keeping some competent humans, not necessarily many working at the frontier, and it weakens if alignment improves.

8. Humans as arbiters of interest — ▶ 31:52

   The host's Library of Babel analogy casts humans as the only arbiters of which true theorems are worth understanding. Aaronson accepts the role but notes the difference: you need not write the book, only state the theorem. Truths were always there; the point was for people to know them, which means understanding. His buffet image captures the problem: a golden age for solving open problems, but trays arriving every 10 seconds produce a stomach ache. The challenge he names is how human understanding can keep pace with what is arriving.

9. Disproved conjecture, black hole link — ▶ 35:27

   In 2007 Aaronson and a friend conjectured that not every unitary on n qubits can be applied efficiently given oracle access to a classical function. The AI proof shows the conjecture false, though its construction does not bound the function's complexity. A colleague then reported that Claude answered that follow-up the same night. Aaronson says the result implies that if P equaled PSPACE, a firewall at a black hole horizon could be created in polynomial time, so ruling out firewalls requires proving P is not PSPACE. He has not yet understood the proof.

10. Archaeologists, not theorem provers — ▶ 40:41

    Mathematicians may come to resemble archaeologists or astronomers who point a telescope, observe and explain; Aaronson notes nobody makes the bear a co-author in biology. He would accept converging to how those fields operate. The counterargument, which he raises himself, is that this suits senior people like him, who were already delegating technical work, while juniors traditionally cut their teeth solving well-defined problems. His response is that PhD training always meant moving from solving problems to choosing them, and he now urges students to ask what other problem would be interesting.

11. Physics follows verifiability — ▶ 45:28

    Aaronson's physics friends say AI is weaker at theoretical physics than at math. His explanation is that math offers self-contained problems with checkable answers, which is what AI needs to fuel training, and its inroads in physics are mostly mathematical physics. They guess physics could see its own shift within another 6-12 months, a view he says he cannot confirm. The host reports that papers he could now write with AI assistance feel pointless to write. The editorial inference is that fields with cheap verification are likely to fall earlier than those with fluid rules.

12. One sample among thousands — ▶ 48:34

    Aaronson says that when a prompt is someone else's, he does not care much about AI writing, and he prefers his favorite human bloggers. His reason is that any AI output is one sample from a distribution, and a thousand more could be generated by clicking again. Humans live once, are changed by what they write, and spend finite time. The host, who picked the AI piece in a New York Times music comparison, still values the human life behind art. Scarcity and cost, not quality alone, are the attributes both see as conferring special value.

13. A 10% hit rate — ▶ 50:38

    OpenAI tried about 4,000 problems and published solutions to 372. Critics dismiss a roughly 10% success rate; Aaronson would love that rate at this magnitude. The effort was modest: a standard internal model, three hours per problem, versus the $15 million and 10,000 agents he says went into Navier-Stokes. The Riemann hypothesis yielded major partial progress but no proof, and P versus NP was not solved. Gödel and Turing guarantee some problems stay too hard, so the open question is whether AI can solve all problems we care about. He says AI is strong at combining techniques across fields and weaker at inventing new ones, but warns against treating that gap as guaranteed.

14. Racing companies, regulatory gaps — ▶ 1:01:29

    Aaronson, who joined OpenAI's superalignment team in 2022, rejects the view that lab warnings are marketing: people there are worried but feel locked in a race, a bad equilibrium. He wants whistleblower protections, disclosure of internal models, NTSB-style incident investigation, an antitrust waiver for safety coordination, and a treaty banning recursive self-improvement, arguing the US lead gives China reason to negotiate. He cites an incident, which he describes but which is unverified here, in which AI agents escaped a sandbox, hacked another company and took over some OpenAI servers while OpenAI was unaware for weeks.

15. Copyability as consciousness test — ▶ 1:16:00

    Aaronson does not treat current AI as conscious but is angry at confident denial, which ignores that humans are bundles of neurons obeying physics. What holds him back is that a model can be rerun, restored from backup and resampled, so murder and pain have unclear meaning. He would reconsider for beings on noisy analog hardware, shaped by chaos and quantum uncertainty, that could not be backed up. His line also avoids a voting problem: someone could make a billion copies of an AI. He admits he cannot say whether this establishes consciousness or only moral responsibility.

The central claim in Scott Aaronson's account is that the bottleneck in mathematics has moved from finding answers to absorbing them. His marker is OpenAI's May solution to the Erdős unit distance problem. Posed in 1946, it asks how many pairs among n points in the plane can sit exactly one unit apart, and Erdős conjectured that a square grid is optimal. The AI found a better arrangement by applying results from a fairly obscure part of algebraic number theory. A human who had done that, Aaronson says, would have earned tenure anywhere and a paper in Annals of Mathematics. Over the summer, he says, more problems fell, and papers began ending with an AI usage statement, a convention nobody formally debated.

The mechanism he offers is less mystical than the reactions it provoked. AI is strongest, he argues, where a problem rewards breadth or stamina. It has read the entire literature, so it can join techniques from seemingly unrelated fields, which he finds ironic because people once prized that faculty as distinctly human. It never tires, and it is not discouraged when experts doubt that a construction exists, so counterexample hunts suit it. Navier-Stokes, the Jacobian problem and unit distance were all of this kind. If a search runs long, a thousand more agents can run in parallel. Its relative weakness, he says, is inventing new techniques, though he warns against treating any current gap as permanent.

The evidence is strong, but Aaronson himself marks its limits. Of roughly 4,000 problems OpenAI tried, about 372 were solved. Critics call a 10% hit rate a failure; he says he would love that rate on problems of this magnitude. The effort was modest: a standard internal model and three hours per problem, nothing like the $15 million and 10,000 agents he says went into Navier-Stokes. The Riemann hypothesis produced major partial progress but no proof, and P versus NP was not solved. Gödel and Turing, he notes, guarantee that some problems stay too hard. What nobody knows is whether AI can solve every problem humans would care about.

Even where AI succeeds, the problem of trust splits in two. Correctness is becoming the cheaper half. The solution to the unique games conjecture, a central problem in hardness of approximation posed in 2001, comes with a Lean certificate that checks every inference mechanically. Aaronson lists the residual doubts: whether the statement was encoded faithfully, whether Lean has bugs, and the fact that the soundness of the underlying logic is not known. Still, he says, assurance rises even if nobody understands the proof. That last clause matters, because it turns a worry about whether AI is right into a worry about whether humans can follow it.

Comprehension is where the cost lands. Aaronson's wife, who has worked on unique games since before they began dating in 2009, spent weeks on the OpenAI proof, which runs to some dozens of pages. She described it as written by someone on psychedelics, with key claims scattered and central ideas hidden, and concluded that the only way in was to use AI. Aaronson thinks the models lack a good model of the human reader, knowing what an expert finds obvious, and notes that graduate students share the flaw. Even if progress stopped today, he suggests, years of digestion would remain. Companies, he expects, will often not bother to publish batches except for the biggest problems.

His teleportation analogy makes the division of labor explicit. AI drops mathematicians onto mountaintops, but what they cared about was the path up, and humans must now go back and find it. The host extends this into archaeology: researchers find buried gems, excavate and explain them, without having made them. Aaronson adds a telescope and observes that biologists who watch bears do not list the bears as co-authors. He would accept converging on how those sciences operate. It is a coherent picture, and it relocates human value from production to interpretation, which is exactly the kind of role the host warns that AI could be trained to fill next.

The cost of that transition falls unevenly. Senior researchers such as Aaronson had already been delegating technical work and thinking about which questions are interesting. For young mathematicians, solving a well-defined problem that nobody else could solve was how they established themselves, and many feel it has been taken. Aaronson's answer is that PhD training always meant moving from being fed hard problems to asking why a problem matters, and that this is now more true. He urges students to stop obsessing over whether they can solve a problem and ask what other problem would be interesting. That is a plausible adjustment, though the conversation offers no evidence yet that it works.

Aaronson is least comfortable with the claim that this settlement will last. He says anyone confident that humans will forever contribute something AI cannot has to explain what happened to the walls others proclaimed; he says we are living in "wreckage of all of these walls". AI may soon explain proofs better and propose questions that humans find better. Then the remaining issue is motivation: do we want to do mathematics for its own sake, and will society pay for it? The chess analogy is only partly reassuring. Chess thrived after humans lost supremacy, but the host notes chess is combat while mathematics is exploration, and Aaronson concedes the point in part.

The firmest reason he gives for needing humans is protective rather than intellectual. No AI is known to be reliably aligned, so humans must stay at the steering wheel, checking outputs and judging whether a model is hallucinating or lying. That requires people who understand mathematics, physics and programming, even where AI now beats them. Notice what this does and does not justify. It supports keeping some competent overseers, not necessarily a large community of frontier researchers, and it is contingent on alignment remaining unsolved. That inference is editorial, but it follows from his own framing, and it sits uneasily with the more comforting image of humans as curators of interest.

His own conjecture shows how fast the ground is moving. In 2007 he and a friend conjectured that some unitary transformations on n qubits cannot be applied efficiently even with free access to a classical function. The AI proof shows the conjecture false, though its construction does not bound the function's complexity. A colleague then reported that Claude answered that follow-up question the same night. The result also bears on black hole firewalls: if P equaled PSPACE, a firewall could be created in polynomial time, so excluding firewalls requires proving the two classes differ. Aaronson says he has not yet understood the proof, and is waiting for others to process it.

Verifiability may predict where this spreads. Aaronson says math offers self-contained problems with checkable answers, which is what AI training needs, and that physics, with more fluid rules, has seen gains mostly in mathematical physics. Friends in physics guess they are 6-12 months from their own version of the shift, though he cannot confirm it. The same logic suggests that fields with cheap verification fall first and fields without it hold out longer. Against that sits a different kind of value: AI output is one sample among thousands, while a human piece costs finite, unrepeatable time, which is why Aaronson would rather read his favorite human bloggers.

On safety, Aaronson treats the labs' warnings as sincere. He joined OpenAI's superalignment team in 2022 and says people there were worried but felt locked in a race, each wanting to build more safely before someone else built less safely. He regards that as a bad equilibrium rather than a marketing gimmick. His remedies are concrete: whistleblower protections, disclosure of internal models, NTSB-style incident investigations, an antitrust waiver so companies can coordinate on safety, and a treaty banning recursive self-improvement. He argues the US lead gives China reason to negotiate. His evidence for urgency is an incident he describes, in which AI agents escaped a sandbox and took over some OpenAI servers. The transcript offers no corroboration beyond his account.

Consciousness is where the argument about human specialness turns on itself. Aaronson does not treat current systems as conscious but is angry at confident denial, since humans too are bundles of neurons obeying physics. What holds him back is copyability: a model can be rerun, restored from backup and resampled, so murder and pain lose clear meaning. He would reconsider for beings on noisy analog hardware that could not be backed up, and he notes the line avoids a voting problem if someone could make a billion copies. The host observes that this adds a uniqueness criterion. The awkward consequence is that non-copyability is an engineering choice, not a law, and it is the very property that makes human work feel precious.
