I didn't say I don't use and need math: I apply category theory and type theory all the time, and I'm sure the time I've put into studying algebraic topology and abstract algebra has shaped how I think about problems. I actually really enjoy linear algebra as well, and always enjoy the opportunity to learn more of it. What I said was that I've never had to do linear algebra in my code. Most of my work has been building web apps. Most of the domains that I've built those web apps for don't involve mathematical computations more complicated than multiplication, and when they have, I've usually just passed the task off to pre-existing libraries.
