Disclaimer: we still have pragmatic reason to follow the evidence suggested by our best scientific theories. I'm just poking fun at scientists in the spirit of Hume. There's no guarantee that the future will resemble the past, and even our best scientific theories are amenable to future evidence.
Dude, like, math is the only thing that I'm confident to say will stay the same in a million years. You could have picked any other example, like biology or even chemistry, but picking math for saying "things could change in the future" is one of the worst (if not the worst) example you could make.
