The core issue in regard to these weapons systems concerns human agency, Goose said.
"The key thing distinguishing a fully autonomous weapon from an ordinary conventional weapon, or even a semi-autonomous weapon like a drone, is that a human would no longer be deciding what or whom to target and when to pull the trigger," he said.
"The weapon system itself, using artificial intelligence and sensors, would make those critical battlefield determinations. This would change the very nature of warfare, and not for the betterment of humankind."

Goose said that pressure from the science and industry leaders, including some rather apocalyptic warnings from Stephen Hawking, helped spur the UN into action.
"The scientific community appears quite unified in opposing the development of fully autonomous weapons," he said. "They worry that pursuit of fully autonomous weapons will damage the reputation of the AI community and make it more difficult to move forward with beneficial AI efforts."
