Technologies built on artificial intelligence are revolutionising human life. As these machines become increasingly integrated in our daily lives, the decisions they face will go beyond the merely pragmatic, and extend into the ethical. When faced with an unavoidable accident, should a self-driving car protect its passengers or minimise overall lives lost? Should a drone strike a group of terrorists, even if civilian casualties will occur? As artificially intelligent machines become more autonomous, these questions are impossible to ignore.
There are good arguments for why some ethical decisions ought to be left to computers—unlike human beings, machines are not led astray by cognitive biases, do not experience fatigue, and do not feel hatred toward an enemy. An ethical AI could, in principle, be programmed to reflect the values and rules of an ideal moral agent.
