"Now, lethally autonomous killer robots would take many forms -- flying, driving, or just lying in wait. And actually, they're very quickly becoming a reality. These are two automatic sniper stations currently deployed in the DMZ between North and South Korea. Both of these machines are capable of automatically identifying a human target and firing on it, the one on the left at a distance of over a kilometer. Now, in both cases, there's still a human in the loop to make that lethal firing decision, but it's not a technological requirement. It's a choice."
