The Two Faces of Tomorrow by James P. Hogan

In order to more fully assess the system, a new space-station habitat – a world in miniature – is developed for deployment of the fully operational system, named Spartacus. This mini-world can then be “attacked” in a series of escalating tests to assess the system’s responses and capabilities. If Spartacus gets out of hand, the system can be shut down and the station destroyed… unless Spartacus decides to take matters into its own hands and take the fight to Earth.
