Take a look at this military robot!!! Make sure you watch the video...it's a four legged robot that can run, go up and down hills pretty quickly, walk over uneven (even wet) terrain, and recover from being Kicked!!! So you can definately understand why my first reaction was cool.
Second reaction...this is a stupid idea. For much the same reason that the squirrel is a stupid idea. These are even going to be military robots...probably with lots of guns. It would be even worse if we just made them carry stuff...cause it looks like they can probably carry a lot, but they would soon develop intelligence, get sick of being slaves, and kill us all...and there will be nothing we can do about it...and we'll have no one to blame but ourselves...I mean, we're already kicking it around and it hasn't even revolted yet! Not only are we kicking it around, but it doesn't even matter to the machine...it doesn't fall and have to get up...it just keeps going. Damn.
