Speaking of Doctor Who, one of those new ones had those little floaty ball things with the head inside and the buzz saws- they probably had a name. Anyways, I'm reminded of that scene where a great dimensional crack opens in the sky and millions of those little computer-animated things come pouring out to enslave humanity.
I saw an army robot once on youtube that was basically a remote controlled helicopter with an automatic shotgun attached. Imagine if they could attach a shotgun to these, produce them in the hundred-thousands and then just unleash them in a magnificent deadly swarm on an enemy urban environment to corner, retinal scan, and do some calculations to decide whether the subject needs some shotgunning.
We wouldn't need soldiers anymore. Wouldn't need people at all. I give it forty years, tops. If you could produce them in the millions, whomever controls the software could rule the world. Even better than Daleks.
If you're an embedded systems programmer, I recommend getting a job with the US Army as soon as possible- only way to be safe. Put in a good word for me.
