Technology has been disrupting human evolution since we learned to bang the rocks together.

You are right. But still I don't quite understand why there are not more smaller dynamic centers popping up. Of course it is NOT only SV and NYC any more. But there would be many other places that are nice enough to attract IT in a substantial way.

It seems riskier to employees if that were the case - if you get laid off or tired of one company in one of these small regional centers and there's only say 5 companies total to choose from, chances are you'll have to uproot your life and move to a new city for your next job which is a big inconvenience.

I think some part of the network effect of big tech hubs is the option value. If you're in the Bay Area you can have the best of both worlds - stay in one place as long as you want for your personal life/family, and still have the possibility of working at any of thousands of the best companies of all sizes and switching between them if you need to.

I think there are some popping up. Austin comes to mind. Takes time for cities to grow, though.

Hipsters, microbreweries, and fancy lattes will continue to spread I am sure!
