“We have servants and machines in order that our will may be carried out beyond the reach of our own arms. Machines are more powerful than servants and more obedient and less rebellious, but machines have no judgment and will not remonstrate with us when our will is foolish, and will not disobey us when our will is evil. In times and places where people despise the gods, those most in need of servants have machines, or choose servants who will behave like machines. I believe this will continue”
