  If you saw TFA and thought "hmmm yes, I know some of those words", then I can recommend the author's own lecture series on YouTube [0]. It's an intro to and overview of category theory aimed at programmers, with the requisite context and motivation for why anyone should care. It's long but worth the time investment IMHO.

    He also has an excellent online/PDF version of the material[0]. All of it is really mind opening stuff, and fun!

    > To understand actegories, let’s start with the definition of a monoidal category

    Definitely not written for someone with my starting knowledge, haha.

  I'd like to understand how and why this stuff is useful for programmers.
