> category theory / abstract algebra Woah there! But otherwise, yes. Most working mathematicians have seen category theory and borrow bits and pieces of notation and such. But most of their work is done in far more concrete settings. Working programmers should adopt the same arrangement. It's a subtle position, but not an inconsistent one. I promise :-)
