Why are billions being wasted on this bullshit when a perfect off-the-shelf design already exists? Nature already created the nano-electric motor a billion years ago. Oh, and the nano-U-joint also.

This is just another case of humans jerking off in front of a mirror, pretending everything's all about us.

It's damnably stupid
