I mean, was the point of math ever just because some humans enjoyed doing it? Even though a lot of it is theoretical, there's been all sorts of useful things that have come out of it as well due to an improved understanding of the universe through new ways of thinking about it. If it got to the point where no human could understand it and there were no ways to actually use it, I don't think anyone would bother having their computers doing it at all.
What would stop you from doing that if AI happened to be doing a bunch of different or more advanced stuff? I assume that the fact that there are humans doing other or more advanced stuff doesn't dissuade you from doing it for fun?
Yeah, that's kind of my point. I would have to imagine that the people investing in AI doing math (using "investing" loosely, not just financial but hardware/energy/opportunity cost as well, which may or may not seem roughly equivalent to money depending on your viewpoint) would just stop unless it remained possible to apply in some way or was understandable by humans.
