It's a good thing, then, that a CS education also trains you in abstract thinking applied to multiple domains. Subjects like mathematics (especially more abstract branches) and CS (especially theoretical CS) are some of the best options for expanding your mind and gaining new perspectives.

Despite the name, computer science isn't actually about computers or even technology. At its core, it's the study of information--very much a dual to certain branches of math and even certain branches of philosophy. "Computer" is just the name given to essentially all the tools used to study information and computation.

Having immediate practical applications does not mean CS doesn't also have significant depth!
