Exactly true. I mean, we absolutely can model humanity and human life using those tools and get great insights into ourselves and how our species functions on a large scale, but to say that doing so with an accurate representation of reality is complex is like saying the universe is just kinda big. But then we have these fucking arrogant stemlord types coming along who learned how solve partial differential equations last week and think the whole of human experience can fit snuggly into some little mathematical curve they thought up in November while desperately trying not to masturbate. And lo and behold, they are full of shit, and no matter how sound their math is, it means fuck all if they're basing it literally on a category error they can't even see because they just can't seem to stop looking at their beautiful, ever-so-smart reflection of themselves in the pond.

Math is powerful. We can use it to better our condition and understand things about ourselves. Hell, it's not as if Marx didn't explain things in mathematical terms at times. But that's just it, we can use it to fuck humanity and the entire biosphere just to ensure line goes up, or we can actually apply it to the real problems we face, i.e., the shit commies talk about.
