Hugh Herr 1: The new bionics that let us run, climb and dance

Hugh Herr at TED2014
The new bionics that let us run, climb and dance  (transcript)
Summary
My thought that technology is now great improving seems to be wrong.
It's because the speaker tells us that deficiencies in technology are the reasons that disability is rampant in the world.
Technology must more eliminate people's disability. Technology advanced can rid the world of disability and it can look disabilities more natural.

Bionics means the study of the functions of living organisms and the use of this information in the design and creation of mechanical systems.

The speaker's thoughts are to bridge the gap between disability and ability and it can succeed by helping science and design. It's called synthetic biology has grown novel technologies.

He lost both legs in a climbing accident. Although it took much time, he could get a new climbing prowess.
Amazingly, his nervous system of residual limb communicate to the bionic limb. Attached the electrical pulse of his muscles is helping.
He doesn't have legs, but when he thinks about moving his phantom limb, the robot tracks those movement desires. He explains that it's used three extreme interfaces in his bionic limbs: mechanical, dynamic, and electrical.
The new bionics that let disability and him run, climb and dance, however, he further seeks to actually feel like flesh and bone.

His thoughts never stop. It's beginning to bridge the gap between human limitation and human potential.

In fact, I understood this story, when I've read his next TED talk. My thought was really bad. Not only technology but also human thoughts are no limits.
