Currently in 2nd year of college, and just now being exposed to calculus based physics: my intended major was computer science, but now I'm not sure. Basically, I want to build stuff that makes people say "holy crap". The problem is that I'm not sure what would be best. If I go mech engineer, I'd probably be working somewhere in the auto industry, and what I make would be heavily restricted to focus groups of consumers... but I'm not sure. The thing that worries me is how far away from pure science "computer science" is now. There are so many software layers on top of the hardware now, that it seems like all people are doing is just figuring out how to make someone else's software do something differently. Is it really even science if you're just memorizing protocols and syntax someone else made up? Honestly, I just want to be Iron Man. That pretty much sums it up. I'd like to build stuff on an unlimited budget with undeserved government money. Is that unrealistic? Advice appreciated. *note: this post may seem goofy, but I mean it in all seriousness. I'd like to pick something where I can work 18 hour days, 10 of them on my own time, building something "woah"-ish. I don't mind hard work as long as there's creativity involved.
