Killer autonomous robots that use algorithms and sensors to determine when to kill people should be banned, the UN has been told. The Campaign To Stop Killer Robots has called on the international community to create a treaty to regulate drones, vehicles and boats that operate on their own. Organisers say artificial intelligence technology is advancing so rapidly that legislation is urgently needed. The treaty would prohibit weapons systems that do not allow human control and those that make kill decisions without human consultation. The group includes Jody Williams, who won the Nobel Peace Prize in 1997 for her work on the International Campaign to Ban Land Mines.
