Eugenia Cheng has a couple of very accessible books on Category Theory

I was going to make the same recommendation. In particular I'd recommend her new book, _The Joy of Abstraction_. It's a real textbook that goes up through the Yoneda Lemma, but it isn't too scary and it doesn't assume that the reader already knows any theoretical math.

Yes, that book in particular. I have Emily Riehl's Category Theory in Context which was not immediately accessible to me at all. Joy of Abstraction aims to be an on-ramp to that.

I read the first couple chapters. It's a bit too watered down in the beginning IMO. I couldn't get past the first part especially when she tries to relate category theory to feminism. Might come back to it later.

As a non-math expert and programmer I highly highly recommend Bartosz stuff I linked it in another branch under my original comment.

Bartosz's material is great but it has a practical programming focus, so Cheng's books which focus more on teach Category Theory as mathematics, make a good complement.

Yeah you're probably right. Ill dive back into her book eventually.

It's mostly the beginning chapters don't even get into the meat of CT quick enough. Instead it spends a lot of time justifying things. I feel It's written for people who hated math even more then I did.
