Clearly this summary is trolling for posts. Robots have killed, and there is a compelling reason to be wary.

Not because robots are going to gain self-awareness and kill mercilessly, but because the human beings using robots for killing are way less careful than they should be. To the fighters in Yemen and Afghanistan, whether the drones are self-aware or not doesn't make a difference to the fact that they are targeted for termination. This is the life they are born in. They are fighting robots which are trying to wipe out their albeit misguided way of living.
Right now people are making the decisions, but what if people lose the stomach? What if the President had the capability to deploy drones which could discern on their own which people are likely to be a threat to US interests? This is almost too close to reality. In fact, the false positive rates of the robots are likely to be lower than people who may be impacted by seeing firsthand what has happened to their fellow soldiers. But does that make it any less worrisome?
