Center for Extreme Bionics

What happens if humans get external or prosthetic nerves?

From Juan Enriquez: What will humans look like in 100 years? | TED Talk

And four of the smartest people that I’ve ever met — Ed Boyden, Hugh Herr, Joe Jacobson, Bob Lander — are working on a Center for Extreme Bionics. And the interesting thing of what you’re seeing here is these prosthetics now get integrated into the bone. They get integrated into the skin. They get integrated into the muscle. And one of the other sides of Ed is he’s been thinking about how to connect the brain using light or other mechanisms directly to things like these prosthetics. And if you can do that, then you can begin changing fundamental aspects of humanity. So how quickly you react to something depends on the diameter of a nerve. And of course, if you have nerves that are external or prosthetic, say with light or liquid metal, then you can increase that diameter and you could even increase it theoretically to the point where, as long as you could see the muzzle flash, you could step out of the way of a bullet. Those are the order of magnitude of changes you’re talking about.

The TED Talk only briefly mentions this aspect, but it’s worth watching to have an idea of the most prominent scientists working on human body augmentation technologies today.
