I mean once they can adapt the technology to signals for the mind. Which version of a camera works closest to the human eye? The original focus and shoot, or this type? I suppose that it all comes down to which one works closer to the real thing. Considering they can already wire up a functional robotic arm to a monkeys brain, and have been able to do optical implants to let blind people see in at least some way... I don't think it too far off from really being possible.
My only worry is... the people that would abuse such a thing. I mean, sure, it'd be nice to have cybernetic replacements for people who have lost their leg, arm, eye, hand, foot, etc... But what about those people, and you know they're out there, who would just use succh technology for less than good intentions?
