Assistant professor (of mathematics) at the University of Toronto, visiting Harvard Fall 2026. Forever confused. Algebraic geometry, number theory, etc. He/him.

New paper with Josh Lam, about which I'm really excited! I want to try to briefly explain what the point is in this thread.

To me the biggest risk of AI is brain rot. I have more and more situations like this. Some coworker shares a report on something they did. I read, and find something fishy. I ask about and get no answer. I ask again and I'm told: the agent said that. And no follow up. It's clear form the interaction that they did not read the report they shared. Their brain is not used as it should be. I am not against AI at all (fortunate for something working at NVIDIA). I use AI a lot. But I use it as a tool. I own the result and whenever I see something fishy I ask about its output I force a change if I am not convinced. I wish there was a way to force people to read the AI output they share with others.

I was part of a group that met last week to try to propose recommended changes to the structure of math PhD programs in an age of AI. Our report, together with a collection of related resources, is now available here: cmsa.fas.harvard.edu/aimathp…

People on this app don't appreciate how well purely human mathematics is doing. People prove major results literally every few weeks, with proofs that are insightful, beautiful, and solve many problems simultaneously. Currently reading this wonderful thing: arxiv.org/pdf/2608.26392

About 40 years ago Siemion Fajtlowicz created Graffiti, a conjecture-generating graph theory computer program. This essay by Fajtlowicz discusses what Erdős thought of this project (and gives some idea what Erdős may have thought of AI). thomasbloom.org/Fajtlowicz.p… 1/

I’d love to read a collection of such accounts by different mathematicians (broadly defined). Some areas (like TCS) are more problem-focused. But even there I think researchers spend their time understanding phenomena and principles that the problems try to capture.

If you could explain what that looks like that isn't *confused looking out the window while muttering under ones breath" then this would be a very interesting piece of writing but no other mathematician has ever managed to do this (that I know of!)

I think I should write something about what the day-to-day work of a mathematician actually looks like. We're not out here doing problem sets!

I.e. my day to day is more like “try to understand this phenomenon.” I might operationalize this by making a conjecture and trying to prove it but it’s not really something that’s easy to scoop. Of course I do keep various well-known conjectures in mind but I don’t think there are any where resolving them would obviate my work.

Must come as a surprise to people here that you don't have a list of top 10 open problems in your office as the target to achieve.

More open letters on AIxMath! I’ve decided I (probably) won’t sign any such letters but these are the closest to my views thus far.
I'm happy to announce two important letters on AI and mathematics. 1. A timely letter on the recent AI advances in mathematics : sites.google.com/view/releas… 2. A general letter on math+AI: sites.google.com/view/math-a… Signatures open to any mathematician with a university affiliation!

Great writing by Martin Hairer, I concur: "The recent releases, on privately controlled websites, of high-profile mathematical results combined with abject levels of scholarship and only minimal presentation effort has been undermining the usual standards of scientific practice. If we refuse to answer when being asked how to do better (irrespective of whether that ask is being done in good faith), how could we then complain about this behaviour?"
Martin Hairer, one of the other members of AGMAI (the advisory group on mathematics and AI), has written a post on the Proofs and Prompts blog that will I hope clarify what our purpose is. The rest of the blog is highly recommended too. proofsandprompts.com/2026/09…

I’m not sure. These lists of open problems definitely contain stuff we would like to know, but it’s not like mathematicians were spending their entire time after the millennium problems, say. For example, in the past 15-20 years there have been several breakthroughs in fluid PDEs, I think the area has been reignited by the connection with convex integration found by De Lellis and Szekelyhidi. This is why lots of people were thinking about the millenium problem on Navier-Stokes, it seemed ripe for solution. But the reality is that mathematicians has been pursuing research directions in a more creative and unstructured way than any problem list has ever captured. This idea that math is a list of problems to be solved and then we are done belongs very much to non-mathematical circles

Astonishing how many posts like this there are about Tao, someone with no apparent arrogance who has spent his life sharing his gifts with the world.
Hey Terence What you are experiencing right now is this weird phenomena called “humbling”. Most of us midwits experienced this in high school or college. If you’re lucky young adulthood. But nobody was ever smart enough to humble you. So we made a machine to ensure you get brought down to earth like the rest of us. When you played down AI some months ago you were in the denial phase. Now you are in the anger phase. Soon you will reach acceptance like the rest of us.

WHAT DO WE WANT? An improved understanding of the arithmetic of isomonodromy foliations. WHEN DO WE WANT IT? Soon.
