I am glad to be "just" an ordinary developer and software architect, not James Cameron. All I wanted, with this submission, was to kindle discussion. Obviously, that goal was reached
:-) The "still" in "still have a human being in charge", however, is tell-tale, and in and by itself already justification enough for wanting to kindle such a discussion, as it is an often-heard argument. You do know, I suppose, that there are already fully automated guardian robots for sale, armed with nothing less than rapid-fire cannons ?
