I am working on some very smart things to say here. Really. Meanwhile, there's 
Beebs on Claudia Mitchell, the second person to be fitted with the bionic arm. Cool video there. What is a bionic arm? From the RIC page:
The "Bionic Arm," or myoelectric arm, is driven using electrical signals from the muscles of the chest, now activated by the user's own thought-generated nerve impulses. These impulses are sensed, via surface electrodes, from the pectoral muscle and carried through to the mechanical arm, causing the arm to move.Very impressive. We can now replace hearts, eyes, ears and limbs. The list keeps growing. I personally would like to see the day when we can replace the stuff between our ears with something more dependable. The future is here and it's not all carbon. There's a lot of steel and silicon too.
