Aubrey de Grey reviews a Brookings volume on the economics of increased longevity. Aubrey has a more optimistic vision than the authors.
rejuvenation research...will anticipate and remedy the life-threatening degenerative changes appearing at newly achieved ages with ever-increasing efficacy and lead time. This will bring about the greatest economic change of all in society: the elimination of retirement benefits. Retirement benefits are for frail people, and there won't be any frail people.
UPDATE: See this interview with Aubrey de Grey, as well as my essay that mentions him. For Discussion. If de Grey is correct and that science will start to solve the problem of rejuvenation, will the AARP be threatened?
