The worst aspect about this is accountability. I've noticed a trend in corporate America where decisions are made less and less by one person, and are now more often made collectively (or at least are given the appearance of having been made collectively). The advantage of this is that, if the decision is made by multiple people, then no single person can be blamed if the decision is a bad one. It's a safe way to manage. If several people can agree to do something, then no one has to take the heat if there is a failure somewhere down the line. "Passing the buck" is, of course, as old as civilization itself, and Harry S. Truman had a sign made for his desk in the oval office that read, "The buck stops here." But in this new method of decision making, the buck isn't passed, and it never lands anywhere, it simply does not exist.
This concept applies to the use of robots. No single person wields the weapon. Many people are involved in the operation of the robot. Therefore, no single person can be held accountable if anything goes wrong. I worry that, in the future, more and more policing will be done remotely. No single person will be making the decisions, so that it will be easier to make poor decisions and get away with it.
