Studying history gives you perspective. You don't need to major in it, but the heart of historical research consists of analyzing all the known evidence from a time/event and trying to logically argue a case for why things happened as they did, and/or finding the weaknesses in others' interpretations. It's not about memorizing dates.
The mainstream in computer science is incredibly ignorant of its own history, and burns a ton of energy reinventing the wheel every few years. (The old school Unix tools still work, for example, they're just fast as heck now because they were written to work on computes with about as much processing power as a bar of soap has these days.)
I'd go so far as to say unix command line tools work much better than the window-based alternatives. Or at least I use them more as time goes on, and use nautilus less.
