D.F Jones' Colussus trilogy. The first book was the basis for a film.
About a new defense system that becomes self aware and decides for our
and Its own security to rule the world.

Victor Milan's Cybernetic Samurai. Near future thriller set mostly in
Japan, about what I would refer to as an AA or AC (Artificial Awareness
or Artificial Conscience) and its painful education in morality.
