Anyone interested in understanding the early history of Silicon Valley should visit Steve Blank’s blog under Secret History. He has posted a recent you tube presentation summary and copy of the slides.
The story provides a compelling view of how military technology development and funding investment during the cold war built on existing industrial strengths in the area before the Venture Capital industry had fully formed. I don’t believe this early history story is understood when countries/regions look to replicate the success of silicon valley.
The story also illustrates the importance that early catalysts (key individuals, ready funding, labs, universities) can have to forming a thriving integrated innovation ecosystem. Very difficult to recreate these conditions today.
