Doomsday headlines warn that the age of "killer robots" is upon us, and that new military technologies based on artificial intelligence (AI) will lead to the annihilation of the human race. What's fact and what's fiction? In The Case for Killer Robots: Why America's Military Needs to Continue Development of Lethal AI, artificial intelligence expert Robert J. Marks investigates the potential military use of lethal AI and examines the practical and ethical challenges. Marks provocatively argues that the development of lethal AI is not only appropriate in today's society--it is unavoidable if America wants to survive and thrive into the future. Dr. Marks directs the Walter Bradley Center for Natural and Artificial Intelligence at Discovery Institute, and he is a Distinguished Professor of Electrical and Computer Engineering at Baylor University. This short monograph is produced in conjunction with the Walter Bradley Center for Natural and Artificial Intelligence, which can be visited at centerforintelligence.org.
