I found this post hilarious exactly about this the other day:

First, it’s AI can’t multiply 4-digit numbers.

Then it’s AI can only, by brute force, get silver in the IMO with specialized systems.

Then it’s OK, well, now a general-purpose model can get gold, but it’s still just the IMO, it’s for high schoolers.

Then it’s OK, it can solve a few trivial Erdős problems, but only because nobody seriously tried them before, they were low-hanging fruit.

Then it’s OK, a lot of serious mathematicians tried this one, but the result was still obvious in hindsight, it just combined knowledge from a thought-to-be-unrelated field, if any human knew that, they would solve it.

And then to OK, but there are still Millennium Prize Problems.

Then OK well it's just Navier-Stokes wake me up when its the Riemann Hypothesis.

Then-

If AI does solve the Riemann it will be the watershed moment when the world realises what has happened.
