It is conceivable that we might have organ replacement for the most commonly failing bodily organs, and cancer treatments that come close to the term "cure". It is inconceivable that any of this will be available to 90+% of the human race, or even to most people in developed countries. Insulin has been available to diabetics for well over a century now. And yet..... well, technology is the not the greatest obstacle.
