At TIME’s Future of Life conference, Ray Kurzweil predicted that advancements in genomics, coupled with nanotechnology and the combination of human and computer intelligence, could extend our life span to 1,000 years.

Kurzweil defined intelligence as “the ability to solve problems using limited resources. And the most limited resource is time.”

The implication is that the smartest thing for us to do would be to eliminate the ravages of time as a variable by prolonging life indefinitely.
