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

I have to say that this was the most blatantly transhumanist mainstream lecture that I've seen in a long time, with sentences like "a human being can never be broken - only technology is broken [because it doesn't allow us to remove all of the human's disabilities yet]". Also generally one of my favorite TED Talks so far.

Note that the implications of the technology go beyond just healing the physically disabled: the exoskeletons he mentions will do wonders to old people. We're looking at the possibility of people maintaining the mobility and ease of movement of a young person for potentially their entire lives, and this technology may become widely available within quite a short time. That means that countless of people might become capable of moving back from nursing homes to living independently with only limited assistance.
