How Terence Tao’s metamathematical insight translates to how we need to think about the economy.

Terence Tao recently did a very good talk at ICM about how AI, in particular LLMs, is changing the field of mathematics. I strongly recommend reading it before reading this post (or even, just reading it and skipping this post, I won’t mind)

Mathematics in the age of AI – Public lecture, International Congress of Mathematicians 2026

In it, he makes a key observation about the alignment of different goals:

What’s notable about this observation is it trivially generalises. I want to apply it, as best I can, to something I’ve been working on and writing about for a while and might make what I mean easier to digest.

The economy is itself an optimization engine with many moving parts. Usually its goals are aligned with what we want, and when it is or isn’t is one of the longest running debates of all time. We use regulation and taxes and subsidies and benefits and tariffs and many other things to try and align it more with what we want, debating over both how well that works and what our “wants” even are.

I’m not here to really bring up one of those smaller debates, they are already going on and I’m no expert on any of them. What I want to do is open up a new one that I think has mostly been missed. I’m no expert in this one either, but I don’t like the fact that I seem to be the only person asking this question. Anyways, enough pontificating, I’ll try and express it in a way analogous to what Tao was getting at.

Wages have two main functions, goals, in the economy.

Moderate the supply of labor.

Provide the foundation for consumptive demand.

By the first I mean: put people into roles the economy needs, encourage them to pursue valuable careers, pick the right degree, retrain if they become displaced, travel to where the work is in the country. This is currently a natural component of our economic optimization machine, it need not be pursued actively.

By the second I mean: almost all consumption is funded by wages. The obvious component is that if you are healthy, of working age, and engaging in society honestly, the money you spend comes from your wage. The less obvious component is that most government transfers, benefits, welfare, also comes from wages. Pensions are paid from a pool of collected wages. Income taxes tax peoples wages (perhaps not your own, but still, wages). VAT or sales tax is a consumption tax, but consumption is mostly paid by wages, so again, the tax is funded in large part by wages.1 This goal is currently almost entirely coincidentally met by its alignment with the first goal.

What AI possibly may do (and an even stronger claim, what automation has already been doing for a few decades) is decorrelating these two goals. It is pursuing one whilst letting the other wither. In some sense, we chose this state of affairs. Consuming from the economy is considered a privilege, and to justify your right to do it you need to prove yourself. Providing your labor has sufficed as that proof for a significant amount of human history. Is that still true, and will it remain true?

To examine this, like Tao, I set up a working hypothesis:

AI tools will, reasonably soon, become capable of performing a reasonable fraction<br>of economically significant cognitive tasks, with reasonable levels of success, quality, supervision, and cost.

The only part I have change from his working hypothesis is “research-level mathematical tasks” to “economically significant cognitive tasks”. I am under no illusion that it is equivalent to his hypothesis. Mathematics has had both an exceptional set of evidenced AI impacts, in excess of other areas, and it can be argued that the nature of mathematical thought is somehow different from the types of cognitive tasks the economy needs done. However, again like Tao, I will ask you to assume that the Working Hypothesis holds.

What does this then mean? If we would like the second goal to be fulfilled fairly, we must modify our societies, cultures, and policies to pursue it. What is “fair” may seem like quite a hard thing to pin down, like it is the very thing we have been arguing about forever. That existing debate is not the one I am trying to surface . The thing is, currently there is almost no distribution of the sort I describe. You might say “but unemployment benefits, social welfare, pensions, free healthcare, free education, are they not already making things fairer?” and the answer is no, not in the way I mean, not if those benefits are funded by taxes that are themselves coming from wages. This isn’t about one person versus another, it is all humans versus technology (and to be clear, I love technology, it’s just if the economy could run on just machines, it would, and humans would neither work in it nor consume from it. That seems like...
