We need a law to ban autonomous robots from killing people on their own initiative. For example, in 2013, the Northrop Grumman X-47B, a prototype sub-sonic aircraft with two bomb compartments and a 62-foot wingspan, autonomously took off from and landed on an aircraft carrier. The proposed ban on autonomous lethal robots is focused upon ensuring that in the future, selecting a target and pulling the “trigger” is always a decision made by a human and never delegated to a machine. There must always be a human in the loop. Today’s computers do not have the smarts to make discriminating decisions such as who to kill or when to fire a shot or a missile. Thus, a ban is directed at future systems that have not yet been deployed, and in nearly all cases, have not yet been built. There is still time to make a course correction. Nevertheless, there already exist dumb autonomous or semi-autonomous weapons that can kill. AI Unverifiable source (2015)
