It's this very narrow definition that is my problem. Your Average Silicon Valley Co-founder can't even imagine that a company could not be about web or mobile apps. I find this apalling.

It makes me wonder whether Peter Thiel is right when he says that the Valley should think more about flying cars and not about 140 characters. I wonder whether the people in the Valley lost the ability to think about anything other than 140 characters.

It sure is a competitive advantage of other high-tech regions in the world: less (or different) tunnel vision.
