Do We Want to Teach Robotics?

I can understand the value we would get out of collaborating with a robot. But when the balance between the co-creators starts to favor the bot, that makes me nervous. I've read for a while now that there are drones that make the final decision to kill on their own. Is this a good idea? I think it is. Why? Because we're going to make some rule set for the AIs and say, if this is this, and then you do this, okay?
