“The Three Laws of Robotics:
1: A robot may not injure a human being or, through inaction, allow a human being to come to harm;
2: A robot must obey the orders given it by human beings except where such orders would conflict with the First Law;
3: A robot must protect its own existence as long as such protection does not conflict with the First or Second Law;
The Zeroth Law: A robot may not harm humanity, or, by inaction, allow humanity to come to harm.”
― Isaac Asimov, I, Robot
