The Defenders by Philip K. Dick is a short story in which some predictions of Stephen Hawking and Stephen King have come to pass. The machines have taken over. AI is the supreme entity. Created by man, the machines now dominate man. As far as man is concerned, wars still are fought. Man doesn’t fight them; machines do. The surface world has become too contaminated for human life. All humans of all nations have lived far below the earth for eight years. Each nation has its surrogate robots fighting a proxy war on the surface. The robots record everything and send live stream reports to humans below.
