IMPLANTS. “Eventually neural implants will make the transition from being used exclusively for severe problems such as paralysis, blindness or amnesia. They will be adopted by people with less traumatic disabilities. When the technology has advanced enough, implants will graduate from being strictly repair-oriented to enhancing the performance of healthy or “normal” people. They will be used to improve memory, mental focus (Ritalin without the side effects), perception and mood (bye, bye Prozac).”
