Found this while I was reading another article. The fact that it had DARPA in the title cought my eye. So I read it and it's very interesting. http://www.popsci.com/science/article/2011-02/darpas-brain-controlled-robotic-arm-could-be-available-just-four-years
So it looks like Cyborgs will be a reality soon. First for simple prostetics, then they'll likely move on to other aplications.
The military will obviously want this for active soldiers. They're allready working on devices to enhance strength. If they
could package it with an arm like this they could do some serious things.
