We must fight the invasion of the killer robots

"Killer robots" are taking over. Also known as autonomous weapons, these devices, once activated, can destroy targets without human intervention. The technology has been with us for years. In 1959, the US Navy started using the Phalanx Close-In Weapon System, an autonomous defense device that can spot and attack anti-ship missiles, helicopters and similar threats. In 2014, Russia announced that killer robots would guard five of its ballistic missile installations. That same year, Israel deployed the Harpy, an autonomous weapon that can stay airborne for nine hours to identify and pick off enemy targets from enormous distances.
