What if I'd like to accomplish something, like building an operating system or a world wide web, and don't really care about the money. What if I just want to change the world. Should I start a company and if so why?
If you want to change the world, you have two ways to do it:
1) By force - in this case, don't do it. Waste of energy on anti-productivity.
2) By creating something people REALLY REALLY want (like your examples) - in that case, yes. Create a company. Find someone as enthusiastic as you. If you create something people want, money will come.
