Here is a commentary I noticed recently, not entirely positive when it comes radical life extension, but the positive portion is quoted below:
Aging, along with the physical and mental deterioration that characterizes it, is undesirable. Potential economic and social difficulties notwithstanding, living longer and healthier lives is a positive and productive premise. Acceptance of the preceding premise leads to the conclusion that the technology that would facilitate radical life extension ought to be pursued.
Dr. Aubrey de Grey, a [biogerontologist] with a formidable beard, offers the argument that it would be morally dubious of us not to develop these technologies and deprive future generations of the benefits therein. To have the ability to develop therapies that lead to longer and healthier lives makes it our responsibility to do so. Policy decisions concerning the adoption and implementation of the policies should be left to those generations in which they are most relevant; it is presumptuous of us to make those decisions for them by not developing these therapies. In his view, it is not only desirable but a moral imperative to give future generations the choice and allow them to decide on implementation. Our hesitation in diverting resources to the development of these therapies is actually condemning future generations to a life span that is far shorter than it could be were we to actively pursue life extension technology. Furthermore, we cannot presume to fully understand the social and political landscape of the future and their priorities - they will be best suited to make a choice and we should allow them to do so.
Without going so far as to characterize those opposed to life extension technology as luddites, there is a serious risk of preventing the potential benefits of these technologies from reaching us, or our children, in time. Some people's fear of what may happen if people live ever longer lives is not a basis for pre-emptive policy decisions.
