Mathematics and AI

Mathematical research (including research in theoretical computer science) is being shaken up by developments in generative AI. The question for us now is – how can we change the publishing/hiring/tenuring trends in our field so that maths doesn't just die. I explain my view of the problem below. But first, here are some writings on the topic that I particularly like:

The recent rush by some mathematicians to feed so many of our problems into generative AI models is leading to an odd situation where humans are currently becoming line-checking referees for machines. This way of working is likely to lead to decreased human understanding in the long run. It is easy to line-check a proof without really understanding the essence of it, and the essence is what is important. As a side note, this way of working also takes the joy out of mathematics – line-checking is one of the least enjoyable parts of being a mathematician – the best part is working together to generate understanding and solve problems.

The combination of the new availability of AI tools and the existing culture in mathematics causes a particular problem for young researchers. Traditionally, PhD supervisors find "somewhat easy" problems for PhD students. The student works on these problems (with the supervisor) – learning along the way. It takes a long time because there is a lot to learn. After that, the student's track record of "problems solved" is the credential that leads to postdoctoral research positions (and to permanent positions). With the availability of AI tools, it is increasingly difficult to find suitable "somewhat easy" problems. A problem that can be solved by a new PhD student is likely to be solvable using current AI models. Recent developments (including the announcement of the solution of the Navier-Stokes problem) make it clear that AI models can already do substantially more.

It is now apparent that the "track record of problems solved" is going to be a bad metric for judging mathematicians in the future, at least in the near future. I agree with Tao that the best solution for the mathematical community may be to put more emphasis on exposition and much more emphasis on high-level understanding.

Mathematics is cumulative, so it is important to keep the literature from being cluttered with incorrect proofs. However, the increasing volume of AI-generated proofs is a real problem – the community can't keep up with checking them or understanding them. Work on formalisation (checking proofs using Lean, or other theorem provers) and AI-based auto-formalisation is useful for this. Two caveats:

  1. Formalisation cannot completely solve the correctness problem – humans would still need to verify that the problems are correctly translated into Lean. Also, Lean and Mathlib can have bugs. Here is an example.
  2. Formalisation is not enough. The ultimate purpose of maths is not just to produce solutions to problems – it is to produce understanding. Formal proofs do not do this. In fact, they are particularly difficult to read because they miss essential intuitive explanation.

Going beyond mathematics, I am worried about the impact on society of the cognitive outsourcing that is occurring.

In any case, (like so many other people!) I think it is time for the maths community (including Theoretical CS) to think about our objectives. AI is a useful tool, which is clearly here to stay. We need to think about the culture and working practices of our field in order to figure out how to use it wisely.

We don't get to choose what is true, we just get to choose what to do about it. So it is a very important time for the mathematics community.

AI use in my own current projects

Despite the fact that I don't agree with Weinreich's full solution (as mentioned above), I don't want substantial AI use in my own collaborative projects. My reason for this is that, although I'm interested in the problems that we work on, I care more about the process of working together, coming up with ideas, and generating understanding than I do about the one-bit answers to the questions themselves. I continue to believe that human understanding is the purpose of mathematics – I did not become a mathematician in order to spend my time as a line-checking referee for a machine.

Not everybody agrees about this, so it seems that collaborators should now agree an "AI policy" before beginning to work together. Here is the policy that I currently propose for my collaborations. I don't really view this as any kind of ideal solution. It is just how I am doing it, for now.

I plan to update this page as frequently as I can – feel free to send me your ideas and thoughts.
