Philosophy is mostly games of words that lead nowhere. Wittgenstein wrote all about it. History is interesting, but too ambiguous and too subjective. Literature is to be enjoyed, not to be analyzed. CS is rigorous Philosophy and, hence, it's a good mental exercise that one can't get in other fields of knowledge.

When you design an algorithm and implement it in code, the computer will not allow you to be ambiguous and imprecise. You made a wrong assumption? Sorry, your program won't work. No partial credit for you. It's tough, but it's fair.
