This article by Paul Graham is about how to create the next hub of innovation.

He focuses on getting smart people mixed with people with money.

What does this mean for all those cities trying to attract talent with buildings or "regional centers". Well, nothing. They're doomed to fail for many reasons. Does it really matter which one is the final straw?

Pittsburgh has many issues. I've been there, and seen it try many times. Perhaps this will be the one successful time. The more targetted the attempts, the less money is needed. But a generation of start-ups, innovation, and success is needed. Otherwise, people retreat to safe jobs.

Will there be another silicon valley? some place where innovation and risk are rewarded? I hope so. Will it be in the US? I don't know.
