Thanks for the feedback. I’d like to elaborate on “friendly to non-mathematician”. The book is written for non-mathematicians with the focus on applications, and, like throwlaplace noticed in their comment, they put a lot of effort to explain the subject for the target auditory: diagrams, pictures, explanations, few proofs. But, after all, it is a maths book on a highly abstract topic, therefore the reader should have some previous exposure to maths and mathematical texts, and expect to struggle, from the very first pages. I think it is impossible to teach category theory to a person who does not have some basic knowledge in undergraduate maths, better in abstract algebra.

>The audience for this book is quite diverse: anyone who finds the above description intriguing. This could include a motivated high school student who hasn’t seen calculus yet but has loved reading a weird book on mathematical logic they found at the library. Or a machine-learning researcher who wants to understand what vector spaces, design theory, and dynamical systems could possibly have in common. Or a pure mathematician who wants to imagine what sorts of applications their work might have. Or a recently-retired programmer who’s always had an eerie feeling that category theory is what they’ve been looking for to tie it all together, but who’s found the usual books on the subject impenetrable. Gives the idea this text should be accessible to those that haven’t seen calculus yet, presumably that would also mean those that haven’t had abstract algebra either. But in reality this book is more advanced than what the average retired programmer or average high schooler could understand on their own. It’s better suited for those that already are familiar with more advanced mathematics. I am not knocking the book. As mentioned, it is probably one of the best introductory books on Category theory currently out there.
