Having a supercomputer control every aspect of your existence is all fine and dandy—until it turns on you. So learns Julie Christie’s home-alone therapist when Proteus, the rapidly evolving techno-brain that runs her first-generation smart-house, holds her hostage with one aim: to impregnate her with its half-human, half-AI spawn. Something like Rosemary’s Baby with a future-shock twist, this what-in-the-hell horror-thriller remains unsettlingly prescient: Demon Seed peers into our cyber-driven future and sees gathering menace.
