Directions: Answer the given question based on the following passage:
Sharp differences would quickly emerge between the society that presses technological advance selectively and blindly snatches at the first opportunity that comes along. Even sharper differences would develop between the society in which the pace of technological advance is moderated and guided to prevent future shock, and that in which masses of ordinary people are incapacitated for rational decision-making. In one, political democracy and broad-scale participation are feasible; in the other, powerful pressures lead towards political rule by a tiny techno-managerial elite. Our choice of technologies, in short, will decisively shape the cultural style of the future.
What is the underlying idea of the passage?
