My guest today is Paul Scharre, author of the book "Army of None: Autonomous Weapons and the Future of War" — which Bill Gates recently featured in his top five book recommendations of the year. Paul is a Senior Fellow and Director of the Technology and National Security Program at the Center for a New American Security — a think tank based in Washinton D.C.   Previously, Paul worked for the U.S. Secretary of Defense where he played a leading role in establishing policies on unmanned autonomous systems and emerging weapons technologies. He led the Department of Defense working-group that drafted policies on autonomy in weapon systems. He also led DoD efforts to establish policies on intelligence, surveillance, and reconnaissance programs.   We discuss the current state of military autonomous weapons, the degree to which highly autonomous warfare will be conducted in the future, and the ethical challenges facing this technology. We also get into the resistance from employees within Google and other A.I companies toward supporting military uses.   More from Paul: https://www.cnas.org/people/paul-scharre Twitter: https://twitter.com/paul_scharre   More at: https://www.MindAndMachine.io
