Leslie Berlin on Silicon Valley's origin story

Leslie Berlin wrote the book on Silicon Valley. The Project Historian for the Silicon Valley Archives at Stanford, she has profiled microchip discoverer Robert Noyce, and her book "Troublemakers," about Silicon Valley in the 1970s, has been called a "landmark event." Berlin takes us back to the '70s, when Ronald Reagan referred to those in the valley as "pioneers of tomorrow." She still sees the region today as "the golden child of the Golden State."
