Either it's useless to worry about killer robots because they're bound to happen anyway, or because it's so far-fetched that it's silly -- which is quite bizarre actually. It's quite simple -- there is a third alternative, very simple. It's a new world order, a planetary order, because OTHERWISE it's clear that it will continue, under nation states, and get drastically worse, and I'm very afraid of where it will take us in a few years. I think it's the only possibility, and an excellent one. It will take a revolutionary act by the UN to accomplish it -- actually taking something seriously for a change -- but I believe it's highly possible and, workable, and it's only right now that it's likely, while america is still in the lead for a few years more.
