I am looking for a short story I read in a collection some years ago.
The main character is a very busy jetsetting businessman who is always plugged into technology. He visits a factory or school which is producing robots that can learn, and when he is there they stop their tasks because they need a reason why.
This man keeps up with his family through a device which monitors their vital statistics and biorhythms. His son makes lists of ages, such as Age of Stone, Age of Bronze, and has added Age of Information. Like the robots, the son has become apathetic and depressed because he doesn't see the point.
