Ethics in AI has received significant attention recently, and the new KDnuggets Cartoon examines the problem of teaching ethics to artificially intelligent entities, like self-driving cars.. The human teacher at a blackboard presents a version of the trolley problem to a class of self-driving cars, where a car is facing a choice between hitting a baby in a carriage or 2 pedestrians. A self-driving car is asking: So what should we do? Drive straight and run over a baby or swerve and hit two pedestrians? What if one of the pedestrians is your mother-in-law?
