I'm not convinced this is a zero sum game. There will be a lot of small Silicon Valleys popping up. And as companies in these little valleys grow and/or die (germinating other companies), they will grow to be the size of SV and maybe support the capital costs of some of the moonshots that take place in SV. SV will always be there to welcome new entrants into the tech industry and foster old ones :). Source: Proud Waterloo-ite surrounded by Ex-Blackberries. Possibly moving to the Valley soon. P.S: Every region that wants to grow will face the real-estate crunch SV is. Look to your municipal laws/stucture to see how your region will weather this storm.
