Robots are becoming more common in our lives. And while they may not have "feelings", perhaps the way we treat them reflects more on our character than we previously thought.
Of course people need ethics. But the current troubles in the technology industry are not evidence of an ethics crisis; it is a public-policy crisis.
Robots have already learned to cheat when playing games. How do we teach them morals if we want them more involved in our everyday lives?
Robots are a twin-edged sword. Used badly, they may one day perpetrate genocide and war crimes. Used well, they can prevent them.
