Mathematistan for All

I do love this map from the Zoog video https://www.youtube.com/watch?v=XqpvBaiJRHo.

Yes, Proof Theory does not show up, neither do Recursion or Set Theory, but the Axiom of Choice is a bright lighthouse in the Ocean of Logic, which at least has a long coast (beach, anyone?) of Category Theory. 

But I hope we can get a nice map of Logic along similar principles and with a similar aesthetics, one of these days. Andres Villaveces tells me he and his students are building one. Meanwhile here's the announcement of my talk at his seminar. The video of me talking pure CT to Andres Villaveces students about Dialectica constructions seems to have disappeared, the link he sent me goes nowhere now. Sad.
