Robot soldiers are coming.
This seems to me to add insult to injury. Imagine sitting peacefully over dinner with your family in your village in some country which has some resource that a bigger country wants, and in runs two hundred robots and kill men, women, and children. Very "nice". Really underlines the tone of the whole thing.
Sure, it'll take years before robots can do this, and until it happens, they will always claim to critics that the robots will be used for other things. But history shows that anything that can kill people will be used to kill people, mainly in war.
One of the rare Danish SF writers, Niels E. Nielsen, wrote a spooky, but excellent book, "Vogteren" or "Vartija" in translation. Well, I was a kid when reading it, but it made an impression on me, especially the central idea which is a "war" waged mainly by automatons, which are moving in one long line (never mind the doability of this) southwards across Africa, and with lasers killing everybody and everything bigger than a field mouse. I think it's a striking image of the inhumanity at the heart of war.
