The truth is, 95% of any degree course material will never be used in the real world unless you go into research. My Quantum theory has never been needed in finance, funnily enough.
I've never employed a CS graduate because the courses are full of stuff that they'll never use - AI, etc. unless they become games programmers (which they almost certainly won't). Mostly the degree type is used to judge the type of person - Maths grads are quite logical people, Science grads are practical people, Arts grads have a head for facts, but CS grads are seen as people who enjoy fiddling around with things without actually getting anything out of it.
Just my opinion, though.
