Do you faint at the sight of blood? Would you faint if that blood were actually grey goo as in a bunch of little robots? Well, that's what this Yahoo article is proposing that someday your blood may be completely replaced by nanites. There has already been many borg-like nanotechnology ideas for monitoring your bloodstream. There has even been Matrix-like ideas for using your blood to generate power for the little guys. But, hey, why not go all the way and just turn yourself into a borg drone. I mean, everyone's doing it so why not? Doesn't it make you wonder just how far us humans might be upgraded (downgraded)? One should draw from the mind just what all the risks might be. As Prince Charles worries, we might just turn whole earth into grey goo. And, what would be worse is if that grey goo was actually self-replicating, aritifical blood. Icky.
