The author of the new memoir, Permanent Record, former CIA officer and National Security Agency (NSA) consultant Snowden risked everything to expose the U.S. government’s system of mass surveillance. He is the subject of the Oscar-winning best documentary Citizenfour and the critically acclaimed Oliver Stone fil, Snowden. Appearing live from Moscow, Snowden continues to speak out about technologies and practices (increasingly by nongovernmental entities) that have created “the most effective means of social control in the history of our species.” “Everything we do now lasts forever. Not because we want to remember, but because we are no longer allowed to forget,” he says, evoking the key theme of Permanent Record. “Helping to create that system is my greatest regret.” As one of the world’s most passionate and authoritative voices on privacy and cybersecurity, Snowden continues to warn us of the growing threats of our digital age.
