We have considered machines marvelous because they can do what man cannot do. We will have a new sense of value in the future, regarding machines as marvelous for doing things as well as man does. In fact, it is easy for machines to do what man cannot do, and it is difficult for machines to imitate what man easily does. The difficult problems will be solved one after another in our age when technology is advancing at a rapid tempo. Robots will then come out of the factories where they have been making products,' making their way far and wide into our living.
