I'd also like to request a "Computer Science has nothing to do with Entrepreneurship" option.
Look, programming is about solving problems and programmers are people who know enough tools to solve those problems. What a CS degree means is that person MIGHT have better tools (being educated in various algorithms and system types). That's all.
Entrepreneurship is about solving one specific problem namely: how to make a company successful. The tools you learn in Computer Science have nothing to do with that. More to the point, neither does what you're programming. A person with the greatest program in the world can fail with no business savvy and a person with a crap program can become a billionaire with enough business savvy.
As for fun, the reality is that all programming requires some fun and some tedious work. Even if you're living your dream programming exactly what you want to you'll still need to deal with tedious stuff like error checking and browser compatibility.
You could also say that computer science has nothing to do with almost all computing jobs since programming tends to be pretty routine in an algorithmic sense. Few people invent non-trivial algorithms.
When building an application, one does not think: will I be doing programming or computer science here?
Who knows what will happen? Maybe the implementation will turn out to be straightforward. Maybe not and some novel algorithm(s) might need to be developed.
Even for routine programming a CS major might be helpful. At least you might have a better understanding of sophisticated library usage (e.g., encryption).
