||Ethical issues associated with AI are proliferating and rising to popular attention as machines engineered to perform tasks traditionally requiring biological intelligence become ubiquitous. Consider that civil infrastructure including energy grids and mass-transit systems are increasingly moderated by increasingly intelligent machines. Ethical issues include those of responsibility and/or blameworthiness of such systems, with implications for engineers who must responsibly design them, and philosophers who must interpret impacts - both potential and actual - in order to advise ethical designers. For example, who or what is responsible in the case of an accident due to an AI system error, or due to design flaws, or due to proper operation outside of anticipated constraints, such as part of a semi-autonomous automobile or actuarial algorithm? These are issues falling under the heading of Ethics of AI, as well as to other categories, e.g. those dedicated to autonomous vehicles, algorithmic fairness or artificial system safety. Finally, as AIs become increasingly intelligent, there seems some legitimate concern over the potential for AIs to manage human systems according to AI values, rather than as directly programmed by human designers. These concerns call into question the long-term safety of intelligent systems, not only for individual human beings, but for the human race and life on Earth as a whole. These issues and many others are central to Ethics of AI, and works focusing on such ideas can be found here.
