The Two Faces of Tomorrow — James P. Hogan

By the mid-21st Century, technology had become much too complicated for humans to handle -- and the computer network that had grown up to keep civilization from tripping over its own shoelaces was also beginning to be overwhelmed. Something Had To Be Done.

As a solution, Raymond Dyer's project developed the first genuinely self-aware artificial intelligence -- code name: Spartacus. But could Spartacus be trusted to obey its makers? And if it went rogue, could it be shut down? As an acid test, Spartacus was put in charge of a space station and programmed with a survival instinct. Dyer and his team had the job of seeing how far the computer would go to defend itself when they tried to pull the plug. Dyer didn't expect any serious problems to arise in the experiment.

Unfortunately, he had built more initiative into Spartacus than he realized....And a superintelligent computer with a high dose of initiative makes a dangerous guinea pig.
