More and more smart people in science, technology and politics, of course. But try to look at the environment around us! more and more damage caused by mankind. It seems that he says "smart people" were not using him in applying the knowledge he had. So (in my opinion, again) should be the heart that controls the head, not the head that controls the heart.
eventually as high as any science we must never forget our moral education, because it as a controller for the application of our knowledge.
