From back cover:

“This technology —controlling and out of control—cannot serve any truly human purpose and has no place in the development of a world of individuals free to create their lives as they desire. So the illusory utopias of the syndicalists and marxists are of no use to us now. But were they ever? The new technological developments specifically center around control, but all industrial development has taken the necessity of controlling the exploited into account. The factory was created in order to bring producers under one roof to better regulate their activities; the production line mechanized this regulation; every new technological advance in the workings of the factory brought the time and motions of the worker further under control. Thus, the idea that workers could liberate themselves by taking over the means of production has always been a delusion.”
