You don't remember what the world was like without robots. There was a time when humanity faced the universe alone and without any friends. Now man has creatures to help him, creatures stronger than him, more faithful, he is no longer alone. (...) For you a robot is a robot. Gears and metal, electricity and positrons. Mind and iron! Human creation! And, if necessary, something that man can destroy. But you haven't worked with them, so you don't know. They are a generation cleaner and better than us.
