If all you do is add numbers together, is it anti-intellectual to question why one needs to grok Principia Mathematica first rather than just doing some arithmetic?

In other words, do you solve problems that actually require category theory or are you just navel gazing?

If you've ever done a map reduce on a dataset you've used category theory, whether knowingly or otherwise.

You don't need more than highschool maths to understand the category theory behind common typeclasses.
