First presented in his 1942 short story Runaround, Isaac Asimov’s Three Laws of Robotics include: 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,” and 3.) “a robot must protect its own existence as long as such protection does not conflict with the First or Second Laws.”

The San Francisco Board of Supervisors just rewrote that first law.
