"The computer industry did not create the personal computer; it was created by people in their 20s who wanted a tool of their own. The Internet was created for the most part by people in their 20s, not the phone company. They didn't know what the tool was for, but they knew that other people would invent uses -- they built the Internet without a central control, to enable innovation."

This is not a new development.

Every single one of the big US industries, from fast food to oil and every single quintessal US artforms, from rock to comics to jazz to science fiction was started by young outsiders. In fact, I think it's possible to generalise this to every industry and every artform.
