Disabled people will use computer implants to regain normal physical faculties

Ray Kurzweil : writer, futurist
Computers will be found inside of some humans in the form of cybernetic implants. These will be most commonly used by disabled people to regain normal physical faculties, i.e. - Retinal implants will allow the blind to see and spinal implants coupled with mechanical legs will allow the paralyzed to walk.
