So if you really think about it, today’s comic brings up several interesting issues regarding robots and war.  One that comes to mind that is certainly not anywhere near a reality, is what if robots are self-aware, does that change the morality of them fighting (I’m thinking Asimov).  If robots are used as soldiers, would they ever fight human soldiers?  If robot soldiers are fighting against other robot soldiers, then is anything really accomplished?  I guess you would be costing each other money, and that’s definitely something, but you’d think it’d be easier to just gamble at that point.  In some ways, I’m reminded of the Star Trek episode where the two countries determined casualties randomly, without ever fighting, and if you “lost” the lottery, you went to be killed.  Deep stuff!
