Recent advances in AI mean that it would now be possible to develop autonomous weapons – systems which are capable of making automated decisions to take human life. Elon Musk, DeepMind and others have signed a pledge never to create AI weapons:
"We the undersigned agree that the decision to take a human life should never be delegated to a machine. It goes on to warn "lethal autonomous weapons, selecting and engaging targets without human intervention, would be dangerously destabilizing for every country and individual."

The signatories have promised to “neither participate in nor support the development, manufacture, trade, or use of lethal autonomous weapons.”
