This is a nice overview of a recent development…  However, a story I find really interesting starts at 4:40.  The video talks about Rebekah Marine, a model who was born without a forearm and is using a high-tech prosthetic hand now.

Despite being born without a right forearm, she overcame all barriers present within the fashion industry, and has become a successful model and humanitarian.

You can read more about Rebekah here.

From the technological point of view, this is a demonstration of how far the field of bionic prosthetics had advanced:

Given enough time, it is not unreasonable to assume that human prosthetics will become indistinguishable in terms of functionality and appearance from real body parts.

And, eventually, may even exceed real body in terms of functionality.
