On: Category Theory Illustrated – Sets

[ilyanoskov]

I think Category Theory is useful in a way that it brings abstractions for many areas of mathematics that used to be considered unrelated to each other or quite distant. It studies interactions between entities, rather than the details about entities themselves.

I think it's quite useful in functional programming languages and gives a lot of insight on how to organise things that in the beginning seem totally unrelated.

[deterministic → ilyanoskov]

I haven’t seen any examples of that in practice. And I was deeply into category theory for a while.
