At South by Southwest on Sunday, MIT professor and double amputee Hugh Herr shared his vision of a future without disability. In the field of bionics, Herr and his team have made incredible strides, such as building powered ankle-foot prosthetics that provide tactile feedback like their biological counterparts, or regenerating neurons in rats and humans. But beyond the possibilities of now or even the near future, Herr gives us a glimpse into a world where, eventually, those with healthy or even mildly suboptimal limbs may prefer bionic limbs, or where having bionic legs wouldn't be an impediment but rather an advantage. We caught up with Herr after his IEEE presentation to learn a little more about the world of extreme bionics.
