The Future of Mathematics: AI’s Impact on the Field

Or, how AI Is Changing Mathematics

Why did the mathematician refuse to argue with the irrational number?

Because there was no point.

— Unknown

My original undergraduate degree is in applied mathematics. Classical Applied Mathematics to be exact. I know, that sounds really fancy, but it isn’t. Soon after graduating with that first undergraduate degree, I decided to get a Computer Science degree because I wanted to make more money. That’s a separate story, but that original math degree drives my interest in this particular topic. Also, the whole AI thing intersects with the “it” thing of the technology industry at moment.

For most of human history, mathematics has been one of the clearest examples of a uniquely human intellectual activity.

We imagine the mathematician sitting at a desk, staring at a problem that nobody has been able to solve. A conjecture becomes an obsession. A new technique is invented. An obscure theorem from another branch of mathematics suddenly becomes relevant. After months or years of work, the mathematician finally sees the connection.

Then, comes the proof.

Read “Uncle Petros and Goldbach’s Conjecture: A Novel of Mathematical Obsession” if you are not familiar with this phenomenon. I own a hard copy. I have for 25 years.

That picture is beginning to change.

Artificial intelligence is no longer merely helping students calculate derivatives or checking whether an equation has been typed correctly. I had a copy of MatLab when I was in college; couldn’t afford Mathematica. Modern AI systems are beginning to discover new mathematical ideas, construct proofs, find counterexamples, and explore problems that have resisted human mathematicians for years.

That raises a much larger question than whether an AI can solve a difficult equation, what happens to mathematics when generating a proof becomes cheap?

The First Cracks in the Wall

The recent history of AI and mathematics is already surprisingly substantial.

In 2023, Google DeepMind introduced FunSearch, a system that combined a large language model with an automated evaluator. Rather than asking an LLM to simply “solve” a mathematical problem, FunSearch generated candidate computer programs and allowed an evaluator to determine which candidates actually worked.

The system produced new results for the cap set problem, a longstanding problem in combinatorics, as well as improvements to the bin-packing problem. It was notable because the system wasn’t merely rediscovering a known answer ; it generated new mathematical knowledge that could be verified computationally.

Then, came increasingly capable theorem-proving systems.

Google DeepMind’s AlphaProof combined language models, reinforcement learning, and the Lean proof assistant. In 2024, it achieved performance equivalent to a silver medal at the International Mathematical Olympiad, demonstrating that AI could solve extremely difficult mathematical problems while producing formally verified proofs.

The distinction is important.

The AI wasn’t merely producing a paragraph that looked like mathematics.

It was producing something a formal proof system could check.

That distinction is about to become fundamental.

Then AI started attacking research mathematics

In 2026, the examples moved further beyond competition mathematics.

An AI-assisted effort involving GPT-5.2 was reported to have resolved Erdős Problem #728, one of the open problems in Paul Erdős’s enormous collection of mathematical questions. The work is particularly interesting because it illustrates a new model of research: the AI generates mathematical ideas and candidate arguments while human mathematicians help guide, evaluate, and verify the result.

Meanwhile, Axiom’s AxiomProver has been reported as solving previously open mathematical problems, including problems involving algebraic geometry and number theory, using a combination of AI reasoning and formal verification.

Now, OpenAI has announced a forthcoming system that reportedly solved ten longstanding mathematical problems, some of which had remained open for decades. The announcement itself has generated considerable excitement and skepticism because the mathematical community is still waiting to examine the complete solutions and understand their provenance and significance.

The individual accomplishments matter, but the more important development is the trajectory.

AI is moving from calculating mathematics to doing mathematics.

Mathematics Has Always Been More Than Calculation

When I was studying math in college (university) more decades ag than I care to count, I was always surprised that people assumed studying math meant you were an accountant. I’m here to tell you that accounting, math education majors, and theoretical math, and applied math are all very different. This distinction between accounting and the last two matters because mathematics isn’t fundamentally about arithmetic.

A computer has been able to calculate enormous numbers for decades.

Mathematical research involves something much harder:

• Deciding which problems are interesting
• Formulating conjectures
• Finding useful abstractions
• Discovering connections between apparently unrelated concepts;
• Selecting the right lemmas
• Constructing proof strategies
• Finding counterexamples
• Recognizing when an approach is a dead end
• Ultimately communicating why a result is important

Traditionally, these activities have been considered the domain of mathematicians.

LLMs are beginning to participate in many of them.

That changes the economics of mathematical research.

The Boring Parts of Proofs Are Suddenly Interesting

One of the most important consequences of AI may not be that machines replace mathematicians.

It may be that machines eliminate a lot of the mundane work surrounding mathematical insight.

Consider what happens after a mathematician has the essential idea for a proof.

The interesting part might be only a few lines_,_ “If we establish Lemma A, we can transform the problem into Theorem B. The result then follows from…”

Everything around that insight can be enormous.

• There may be dozens of intermediate lemmas.
• Definitions have to be made precise.
• Edge cases have to be handled.
• Existing theorems have to be located.
• Notation has to be reconciled.
• Arguments have to be expanded.
• A proof may have to be translated into a formal language such as Lean.
• Every tiny logical dependency must be checked.

This is exactly where AI can become extraordinarily useful.

Research on Lean Copilot, for example, has demonstrated LLMs integrated directly into the Lean theorem-proving environment. In experiments using Mathematics in Lean, the system substantially reduced the number of manually entered proof steps and automated a large portion of the proof construction process.

This suggests a future in which a mathematician might say_,_ “I think this lemma is true. Here’s why I think it should work.”

The AI responds_,_ “I believe so. Here are three possible proof strategies.”

The mathematician chooses one.

The AI expands the argument.

Lean checks it.

The AI finds a missing condition.

The mathematician fixes the conjecture.

The AI tries again.

Eventually…proof verified.

That is very different from asking ChatGPT to solve a homework problem.

The Emergence of the AI Mathematician

This suggests that we may be moving toward a new mathematical workflow.

Today, a simplified model looks like:

Human Mathematical Process (Generated by ChatGPT) / Author

The emerging model looks more like:

Human + AI Mathematical Process (Generated By ChatGPT) / Author

The machine becomes an enormous mathematical search engine.

It can explore thousands or, potentially, millions of possibilities that no individual mathematician could examine.

The human becomes the person deciding which possibilities are worth exploring.

That distinction may become increasingly important.

Proof Generation and Proof Understanding Are Different Things

There is a philosophical problem lurking here.

Suppose an AI produces a formally verified proof of a difficult theorem.

Is the theorem now understood?

Not necessarily.

A formal proof establishes that a conclusion follows from its premises according to the formal system, but mathematicians care about something more. They want to know why this is true.

A 50,000-line machine-generated proof may be completely correct and yet provide almost no useful intuition.

Human mathematicians often try to find the short proof, the beautiful proof, or the proof that reveals the underlying structure.

This is one reason human mathematicians are unlikely to disappear from the process.

The goal of mathematics isn’t merely to accumulate true statements.

It is to understand mathematical structure.

The New Scarcity: Mathematical Taste

If AI becomes extremely good at generating proofs, something new happens.

• Proofs become less scarce.
• Ideas may become less scarce.
• Calculations become nearly free.

What becomes scarce?

Mathematical taste.

A mathematician might eventually have access to an AI capable of generating hundreds of plausible conjectures every hour.

• But, which one should be investigated?
• Which problem matters?
• Which result is profound?
• Which apparent connection is actually important?
• Which theorem opens an entirely new field?
• Which result is merely technically clever?

These are not purely computational questions.

They are questions about judgment.

And, judgment may become one of the most valuable skills in mathematics.

Terence Tao has made a similar observation in his recent discussions of AI-assisted mathematics: he argues that as AI reduces the cost of routine mathematical work and exploration, the relative importance of choosing good problems, designing effective workflows, and checking and interpreting results increases.

What Happens to Mathematics Education?

This may be where the consequences become most profound.

For generations, mathematics education has been organized around a progression:

AI disrupts every stage.

A student can now:

• Ask an AI to solve a differential equation.
• Explain the solution.
• Generate ten similar problems.
• Grade the student’s attempt.
• Provide another explanation.
• Find the student’s mistake.
• And, potentially, generate a proof.

That doesn’t make mathematics education obsolete; It does change what we should be teaching.

The important question may no longer be can you solve this problem?

It may increasingly become:

• “Can you understand the solution?”
• “Can you determine whether the solution is correct?”
• “Can you find a better approach?”

And, eventually_,_ “Can you formulate a problem that is worth solving?”

That is a very different educational philosophy.

The Mathematics Professor Is Going to Change

Good. Here’s to you Dr. Schwartz.

This has uncomfortable implications for the traditional college mathematics professor.

A significant portion of undergraduate mathematics education consists of teaching techniques that machines are increasingly capable of demonstrating instantly.

> A professor may spend hours explaining a particular integration technique.

An AI tutor can demonstrate hundreds of examples on demand.

> A professor can explain a theorem.

An AI can explain it ten different ways.

> A professor can generate homework.

An AI can generate infinite homework.

This doesn’t mean professors become unnecessary.

It means their value moves upward.

The professor becomes less of a mathematical answer dispenser and more of a:

• Mentor
• Researcher
• Curriculum designer
• Intellectual guide
• Critic
• Evaluator
• Teacher of mathematical thinking

The classroom may consequently become less about transmitting procedures and more about developing judgment.

Students might spend less time asking_,_ “How do I solve this?”

And, more time asking_,_ “Why is this the right problem?”

What Happens to the Mathematics Major?

They become fantastically sarcastic application security architects.

Some may view this as an uncomfortable question. Be more flexible — here’s to you John.

If AI can solve many advanced mathematical problems, why should someone spend years learning mathematics? Do not ask what your math degree can do for you, but what you can do for your math degree. Or, wait, maybe it was, “What can’t you do with you math degree?”

The answer may actually become more compelling, not less.

Learning mathematics teaches something deeper than the ability to perform mathematical operations.

It teaches abstraction.

It teaches rigorous reasoning.

It teaches how to construct and criticize arguments.

It teaches how complicated systems can be represented with simple structures.

Those skills become more valuable when AI is available.

A mathematician who understands mathematics can use AI as a research instrument.

Someone who doesn’t understand mathematics may be unable to distinguish a brilliant theorem from an extremely sophisticated hallucination. I have an image in my mind of a haze of bong smoke as I write this.

Formal Verification Becomes the Safety Belt

This is where systems such as Lean become particularly important.

LLMs are probabilistic systems.

They can produce plausible nonsense, which is the best kind.

That is tolerable when generating a marketing slogan.

It is unacceptable when proving a theorem. Again, haze of bong smoke.

A formal proof assistant provides a fundamentally different mechanism.

The AI can propose, “Here is a proof.” The proof assistant responds, “Show me.”

Every logical step must satisfy the formal system.

This creates a powerful architecture:

• AI for creativity.
• Formal systems for correctness.
• Humans for meaning.

That combination may prove much more powerful than any of the three individually.

Research such as Lean Copilot demonstrates precisely this direction: using LLMs to generate proof steps while relying on Lean to provide rigorous verification.

This may very well allow humanity to go deeper into Mathematics than it ever could on its own.

The Human Mathematician Isn’t Going Away

There is a tendency whenever AI achieves a new capability to ask, “Will this replace humans?” For Mathematics, that is the wrong question.

A better question is what parts of mathematical work should humans continue doing?

It seems increasingly likely that machines will take over more of the mechanical components:

• Searching mathematical literature
• Finding relevant lemmas
• Checking calculations
• Generating proof variants
• Formalizing informal arguments
• Exploring enormous search spaces
• Finding counterexamples
• Verifying proofs
• Translating between mathematical representations
• Filling in routine proof steps

Humans will continue to contribute disproportionately to:

• Choosing important problems
• Developing mathematical intuition
• Interpreting discoveries
• Determining significance
• Creating new mathematical frameworks
• Deciding what deserves attention
• Communicating ideas
• Connecting mathematics to the physical and social world

The boundary will move, but it probably won’t disappear.

Research Becomes a Conversation With Machines

The most interesting possibility is not an AI mathematician working alone.

It is a human-AI mathematical research team.

Imagine a mathematician working on a difficult conjecture.

The human gives the AI the problem.

The AI searches the literature.

It identifies an obscure theorem from a neighboring field.

It proposes a possible connection.

The mathematician recognizes that the connection is interesting.

Together they formulate a stronger conjecture.

The AI searches for counterexamples.

It finds one.

The conjecture is revised.

The AI discovers another pattern.

The mathematician realizes that the pattern suggests an entirely new mathematical object.

The AI helps formalize the definitions.

It generates lemmas.

Lean verifies them.

Eventually the mathematician writes the paper — not because the AI couldn’t write it, but because the mathematician understands what the result means.

That may be the future of mathematical research.

Not humans versus machines, but humans thinking with machines.

The Biggest Change May Be the Amount of Mathematics We Can Do

There is another possibility that is easy to overlook.

AI may not reduce the number of mathematicians.

It may increase the amount of mathematics being done.

If proof search becomes dramatically cheaper, researchers can investigate questions that previously weren’t worth pursuing because the technical overhead was too large.

Entire classes of conjectures may become computationally approachable.

Mathematical databases may become enormous laboratories of machine-generated conjectures.

Formalized mathematics could become searchable in ways that traditional mathematical literature never was.

And, mathematicians could increasingly treat AI systems as experimental instruments.

In physics, nobody asks whether a particle accelerator makes physicists obsolete.

The accelerator lets physicists investigate questions that were previously inaccessible.

AI could play a similar role in mathematics.

The whole line of reasoning in this section leaves out the economic and environmental costs associated with running AI / LLM algorithms to explore these questions. The “amount” of new topics explored will almost certainly increase, but I think the real benefit will be how deep we can go in meaningful results.

A New Division of Labor

The future may therefore produce a new division of mathematical labor.

Humans: Choose. Understand. Interpret. Generalize.

AI: Search. Generate. Explore. Construct.

Formal systems: Verify.

That division is powerful because each component does something the others struggle to do.

AI provides scale.

Humans provide judgment.

Formal mathematics provides certainty.

Mathematics After the Proof Bottleneck

For centuries, mathematical progress has been constrained by the amount of intellectual labor required to turn an idea into a proof.

That bottleneck may be disappearing.

That could fundamentally change the nature of mathematical discovery.

If generating a proof becomes inexpensive, the scarce resource will no longer be proof production.

It will be good mathematical questions. Again, the image of bong smoke expanding towards the horizon.

The mathematician of the future may therefore spend less time proving theorems and more time deciding which theorems should exist.

• Less time filling in the algebra.
• More time discovering the structure behind it.
• Less time searching for the missing lemma.
• More time asking why the lemma should be true in the first place.

And, perhaps, most importantly, less time working against the complexity of mathematics and more time exploring what mathematics can reveal.

The machines may eventually become extraordinarily good at proving that something is true, the most interesting question will remain stubbornly human:

Why should we care that it is true?
