explaining to someone who is not completely insane that "categories," "groups," and "sets" are three entirely different things

of course they are! groups contain the concept of an operation on members of a set, and a category is just whatever you want it to be

Man, everything should just be a function.

Once had an interview where the guy asked me “what is a function” and kept telling me I was wrong when I said it was a map between two sets, he wanted a very specific definition of a function as a set of ordered pairs of elements of each set smh.

Bullet dodged, then?
