      I have tried to read several books about category theory, but they all appear to dissolve into lists of trivial details before they ever clearly say anything new or powerful. Is category theory really just the idea "hey we can draw equations in 2D instead of 1D",

      and then all these books are just listing out what that looks like, or is there really a separate body of ideas about something that isn't already covered everywhere else?

      (Not to discount the potential strength of the idea of doing equations in 2D, it's just, everyone seems to be claiming it's more than that, but I don't see it, and I am trying).

      Just like every other one of these, I am 62 pages in and super bored and do not see the point.

      Like, I want to know what is actually useful about category theory, or whether it is snake oil.

          This thread has some interesting commentary: https://mathoverflow.net/questions/19325/most-striking-applications-of-category-theory/80662#80662 … "Algebraic K-theory... it was a relief to finally see an example of category theory being used in an essential way to do something that was not just linguistic."
