“Even just within our species, 150,000 persons are destroyed each day while countless more suffer an appalling array of torments and deprivations. Nature might be a great experimentalist, but one who would never pass muster with an ethics review board – contravening the Helsinki Declaration and every norm of moral decency, left, right, and center. It is important that we not gratuitously replicate such horrors in silico.”

— Nick Bostrom, Superintelligence: Paths, Strategies and Dangers, Chapter 12: Acquiring Values (2014)
