Ever since science began seriously investigating the potentials of electronics, man has toyed with the idea of creating robots. The dawn of the robot age has already broken. We have automatic telephone exchanges. We fly planes with robot pilots. We send self-sufficient instruments into the void to record and transmit cosmic information.Frobisher was a brilliant theorist, years ahead of his time. He worked out a scheme that took long patient decades of planning. His great moment came. The robots were a success. Frobisher was a kindly old man. There was nothing evil in his plans.
