Why do the classes you take in college HAVE to help you with your work programming? Can't you just take something because you're intellectually interested in it? Or because it has an awesome teacher, or a lecturer who is world famous, or a Nobel laureate teaching it?

As long as you're genuinely interested in what you're taking there's no reason not to take it. Not everything is about learning how to do one job that you're stuck with for the rest of your life.
