Joseph Menn's new book The Cult of the Dead Cow: How the Original Hacking Supergroup Might Just Save the World dives deep into the history of not just the cDc, but also the hacking culture that emerged in the 1980s and 1990s and has produced some of the most influential hackers, executives, artists, and even politicians working today. Dennis Fisher talks with Joe about the cDc's founding, its members, its lasting influence on the tech industry and the world at large.
