Silicon Valley’s long and complicated relationship with the US government has gone largely unchronicled. Until now – in The Code Margaret O’Mara opens a significant new window into that history. She has captured a portrait of an industry that has until now largely operated outside of the public eye. The Code reveals that Valley is both more of a creature of its partnership with government and an increasingly powerful influence upon it. The Code is an important addition to the literature that seeks to understand Silicon Valley and its impact on the entire world.” —John Markoff, author of What the Dormouse Said
