Si. I really think the role of history here is important- there is nothing new or especially important about the current burst of innovation, or as Joseph Shumpeter termed it, creative destruction. We are just in another phase of human and economic history- and the valley is a remarkable centre of a lot of this innovation. However the same rules of hype, hyperbole, boom and bust that have governed all pervious cycles of human history still work in the information age. So none of this is new, and it won't be the last time it all happens either!
