This text examines the computer revolution and the rise of a high- tech underground counter culture, whose members are using the technology in ways never intended by the manufacturers. It examines would-be cyborgs who believe the body is obsolete and dream of downloading their minds into computers, cyber-hippies who boost their brain power with smart drugs and mind machines, and on-line swingers seeking cyber-sex and cyber-punk roboticists. Dery poses the question, will this technology liberate or enslave us in our emerging digital world?
