Look at the advances in less than a decade. Here's a video from May 2016 from IEEE Spectrum . Mashable - Luke Skywalker hand for amputees It's like you have a hand again. Amputee makes history with mind control limbs. Prosthetic Hand Restores Amputee's Sense of Touch Luke Arm (Sept. 2009) How long did Luke Skywalker have to wait for his prosthetic arm?

The human arm (counting the hand also) has 22 degrees of freedom (DOF) (movements like forearm rotation). The traditional hook and cable prosthetic has just 3 DOF.
