Online, we fall prey to the illusion of companionship, gathering thousands of Twitter and Facebook friends, and confusing tweets and wall posts with authentic communication. But this relentless connection leads to a deep solitude. MIT professor Sherry Turkle argues that as technology ramps up, our emotional lives ramp down. Based on hundreds of interviews and with a new introduction taking us to the present day, Alone Together describes changing, unsettling relationships between friends, lovers, and families.
