Random thought of the day:
I don't see any mention in this article of "social networks". Even if an entrepreneur can be smart and driven, can learn a wide array of technical skills on his own, if he is literally on his own he is going to be at a serious disadvantage.
Some people acquire a network of cofounders, lawyers, and financiers through their parents' social networks, and some people can acquire them online or off with no help, but maybe, maybe if you're a smart, driven individual with no pre-existing social network, it might be worthwhile to go to college to meet that special someone you could settle down and start a company with?
