I think this is awesome. The best comment I read on the above link said something like "All those years of playing Doom finally can pay off." Think of if signing up for the draft essentially meant signing up to play Call of Duty: Iraq. Think of Ender's Game becoming a reality!
What's the worst that can happen? We have to fight robots for control of the Earth? That's not that bad. It's better than fighting other humans for control of the Earth. It's a much more black and white issue. Plus, you don't have to feel bad about destroying robots. It's probably easier to destroy a robot than it is to command a robot to destroy another person, right?
I give this, and any sort of Judgment Day scenarios that could result from it, an enthusiastic thumbs up!
