That is a level of alarmism that will be ultimately unhelpful I think. While it is true that absence of evidence is not proof a threat doesn't exist, shaping our actions based on so far unseen, potential risk is unwise. Somehow I suspect we will not go from mindless herds of killer cyborgs to single, excruciatingly intelligent shapeshifting spies in our midst in one fell swoop. In the meantime I'd prefer not to get shot again because I occasionally look and act like a wild monster.
