Artificial Intelligence is changing warfare. Fully autonomous weapons that can make their own decisions about what to target or whom to kill are already in limited use today. But the pace of development of AI suggests that these so-called "Killer Robots" may become more and more common in future armed conflicts. Meanwhile, the speed at which new AI technology is coming online far exceeds the ability of the international community to come up with guardrails that might place controls on fully autonomous weapon systems. Guest Paul Scharre is the Executive Vice President and Director of Studies at the Center for a New American Security. He is the award-winning author of Four Battlegrounds: Power in the Age of Artificial Intelligence. We kick off by discussing what we mean by autonomous weapons before having a longer conversation about what the future holds for AI in warfare, nuclear security, and how to secure sensible regulations on autonomous weapons and military uses of AI.
