Remember that cheesy line from Spiderman about great power bringing great responsibility? In the event that great intellect allows a person to attain wealth and/or power, I would sleep better at night knowing that person understood some past mistakes of the wealthy and powerful, and they had at least considered some of the collective guidance of humanity.
If the question were constrained to CS, then I would say Compilers. But that's a loaded answer, since it damn near requires a CS degree to truly appreciate compilers.
If you want to have fun and know yourself better, take a class in art or music.
