It begs the question, how long before we can build the whole 'Terminator'?

Nigel Ackland, 53, is lucky man, he has recently been fitted with a carbon fiber mechanical arm which he controls with muscle twitches from his upper arm. It's called the bebionic3, it moves like a real human arm and hand and can do everyday things like crack and egg, type on a keyboard, and for the first time since Nigel's accident 6 years ago when he lost his arm, he can now dress himself.

Technology is amazing.
