In the famous sci-fi TV show Battlestar Galactica, John Cavil, a Cylon that appeared human, went on an epic rant that forever changed my perception of biology and my own biological substrate. It was there that he stated, "I know I want to reach out with something other than these prehensile paws and feel the solar wind of a supernova flowing over me. I’m a machine, and I could know much more. I could experience so much more, but I’m trapped in this absurd body!"

To feel trapped inside of a body that doesn't obey to your desires is a commonly-held feeling - especially among the disabled community. Whenever someone is amputated, it's quite common for that person to experience what is known as "phantom limb" - a phenomenon whereby an amputee is able to feel their missing limbs but is incapable of moving them (for obvious reasons).

And while modern technology has certainly helped alleviate a lot of the discomfort that comes with being an amputee, nothing has yet been able to directly address the phenomena of phantom limb - until now.
