"Suppose that machines take the next step in their own kind of evolution and arrive at a stage where they actually do do their own thinking--become rational individuals able to plan and execute. Would humankind have to knuckle under and let them run the earth? If so, how do we go about recovering control? 'Millennium I' opens with 'homogrub' living in caves, hiding from the rational machines which are not only in complete control but possess new and almost incredibly powerful means of destruction. But rebellion among men grows--first in the form of individual acts of sabotage, and then in a daring expedition by a small group into the very heart of the mechanized world"--Dust jacket front cover flap.
