Stephen Hawking warns that robots could replace humans

A report by Human Rights Watch and the Harvard Law School International Human Rights Clinic calls for humans to remain in control over all weapons systems at a time of rapid technological advances. It says that requiring humans to remain in control of critical functions during combat, including the selection of targets, saves lives and ensures that fighters comply with international law. 'Machines have long served as instruments of war, but historically humans have directed how they are used,' said Bonnie Docherty, senior arms division researcher at Human Rights Watch, in a statement. 'Now there is a real threat that humans would relinquish their control and delegate life-and-death decisions to machines.' Some have argued in favor of robots on the battlefield, saying their use could save lives.
