Well, but we know that in the 24th century, apparently everybody needs an understanding of basic calculus. Just curious what for. I don't mean I can't think of truckloads of applications, being an applied mathematician myself, but I simply don't think everybody needs an understanding of it, today (though I wouldn't be against it) the same way basically everybody needs to learn how to read and write today or you won't get very far in our society. So I'm curious what has changed in the 24th century, also given there probably is so much intelligent software and machinery around that could do this stuff for the average user if he ever even needed it. So is this 'need' an actual need, or is it simply considered some basic part of general knowledge, the same way most of us learn about world topography and classical literature and then rarely use it again in later life?
