Human societies have, historically, undergone a number of moral revolutions. Some of these have been precipitated by technological changes. Will the integration of robots into our social lives precipitate a new moral revolution? In this keynote, I will look at the history of moral revolutions and the role of techno-social change in facilitating those revolutions. I will examine the structural properties of human moral systems and how those properties might be affected by social robots. I will argue that much of our current social morality is agency-centric and that social robots, as non-standard agents, will disrupt that model.
