“[For example,] in the age of the information explosion, all the walls go out between age-groups, ethnic groups, between family groups, national groups, between economies. The walls all go out. People suddenly have to adjust themselves to this new proximity, this new interrelationship, and merely to tell them that this has happened isn’t very helpful. What they need to know is, if it is happening, what does it mean to me? For example in the matter of, say automation and jobs.”
