The sad thing is, the fact that they need to be banned indicates that they are almost certainly going to be used.
Russia already has a doomsday device that is a robot designed to launch a mutually assured destruction attack against the West if it senses Russia has experienced a nuclear bombing.
It was created after a Soviet refused the order to launch a MAD attack in response to flakey intel readings.
It is still armed and alive.
The people who claimed to want them banned are the very ones who relish the idea of having a robot army implement their will on the rest of us.
