On Cyberware

I've read through this book, and the standing detail that seperates it from modern technology is the prevalance of Cyberware.
This seems to be the deciding factor of Cyberpunk, and thusly, I've been doing some research on the real life equivelant, Prosthetics.

The field seems to be quite advance, though the major problem is that their is no real technology at this point, which allows electronic devices to directly interface with nerves. We are one breakthrough away from developing a system where a prosthetic limb directly interacts with the body, rather then through minor pumps. Where moving a prosthetic hand is like moving an actual one.
