This week, the first meeting of the Convention on Conventional Weapons (CCW) Group of Governmental Experts on lethal autonomous weapons systems is taking place at the United Nations in Geneva. Organizations like the Campaign to Stop Killer Robots are encouraging the UN to move forward on international regulation of autonomous weapons, which is great, because talking about how these issues will shape the future of robotics and society is a very important thing. Over the weekend, however, I came across a video that struck me as a disturbing contribution to the autonomous weapons debate. The video, called "Slaughterbots" and produced with support from Elon Musk's Future of Life Institute, combines graphic violence with just enough technical plausibility to imagine a very bleak scenario: A fictional near future in which autonomous explosive-carrying microdrones are killing thousands of people around the world. We are not going to embed the video here because it contains a number of violent scenes, including a terrorist attack in a classroom (!). You can find it on the Future of Life website.
