In his painting, Saturn Devouring His Son, Francisco Goya depicts the Titan, Cronus, devouring one of his children. The painting represents the Greek myth wherein Cronus devoured his children out of fear of being overthrown. In the end, Cronus was defeated by his children. In an other archetypal parent child relationship, the Greek tragedy, Oedipus Rex, King Laius attempts to murder his infant child, Oedipus, when an oracle predicts that Laius will be slain by his son. As the oracle predicted, Oedipus, though unwittingly, fulfilled the prophecy. Such tales of parents fearing their supplantation at the hands of their children are prevalent throughout history; perhaps they can serve as useful metaphors for the friendly artificial intelligence (AI) conundrum we are faced with today.
