The chain goes like this: Everyone's favorite programming language (Python, JS, ...) gets (much of) their concepts from Haskell and Haskell gets its concepts from category theory. Thus, by studying CT you enable yourself to see these concepts in the programming languages you use at work. This can make it easier for you to read, write and reason about programs, since you are provided with new (previously unknown) ways to think about it.
