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.
