I think his projections are premature at best. Something of this magnitude may be a possibility, but not within my lifetime. Working in the medical field also alows you to see the red tape that presents itself every step of the way. Finally, if this type of regenerative ability actually comes into existance, the government has a lot of reasons to contain it, harness it, and deny it to the general public.
But imagine the value of such a thing to someone with no faith in God. Even more, imagine the value of this to someone who fears hell.
Final note: If this type of "life" comes into existance and becomes our "given right", who are we to deny individuals in the prison system their everlong life? Now there is your tax dollars at work! At least you will have a 1000 years to pay for their 1000 sentence in prison.
Sure they'll let us live forever.
