I like that Brad touches on the time-factor of 20+ years. I think it's easy to forget that it takes a long, long time to create a sustainable business environment, and it also takes years of success stories and phenomenal leadership to put a city on the entrepreneurial map. SV has made more than a few good tech companies. Hollywood has made more than a couple good movies. NY has made more than a handful of innovative finance companies. These legendary communities have created extraordinary results, but they didn't become legendary overnight.
