I don't necessarily think that that is true, as almost every social science has been turned into maths one way or another, beginning with Economics. Heck, even mundane stuff like sports (think football/soccer) has now been absorbed by data, which you can see as applied maths.
Yes, I do know that advanced maths doesn't currently explain Arteta's system at Arsenal but we're generally talking about that same semantic area of interest, i.e. if the interest on maths were to subside as a result of AI taking that interest away from us then we will have no more data/stats-focused Artetas in the future (and possible no AI-like thingie also).
I’m saying that this wouldn’t have happened had our society not become “mathematics-ised” at some point (I’m talking about said society’s technical and scientific elites, of course). I’m also saying that outsourcing our “mathematics-mind” to AI (which seems the current process we’re now part of) will not allow for similar “mathematics-ing” to take place into the future. I’ll come with an even stronger claim and say that we risk losing the “mathematics-ing” we now associate with most of our sciences.
But it's a construction based on very basic properties of the real world, at least on those properties we accept and perceive as very general and we use them as building blocks.
