A comment on With Category Theory, Mathematics Escapes from Equality (2019).

I bought a book on Category Theory by Emily Riehl that I find myself unable to get through. I both find her talks on YouTube to be more digestible, and I also wish I was better at mathematics.

Yeah, in the continuum of texts on category theory, Riehl’s book is somewhere on the advanced side…

What exists in the most elementary side?

On a reasonably elementary level, I like Perrone's Notes (with examples from basic math) and Barr's book "for computer scientists."

Books for a more general audience I know of are Conceptual Mathematics by Lawvere and Schanuel, and one "for the sciences" by Spivak.

I learned a lot from The Catsters on YouTube, way back in 2007 or so.
