Editor’s Note: In this guest post, Tom Alberg, Madrona Venture Group managing director, reviews The Code: Silicon Valley and the Remaking of America by Margaret O’Mara; and VC: An American History by Tom Nicholas. The accelerating growth of the tech economy during the past 70 years has generated numerous books seeking to capture its dynamics. Two recent books are worthy additions and reads, one by a University of Washington professor and the other by a Harvard professor.
