There are so many inter-related factors involved with changing a system of this complexity. My fear is the creation of half living zombies that don't die, but who's brains have long since moved on. Zombies, who not incidentally, keep title to accumulated resources for very long periods of time and presumably hold office and vote. This might sound bad... but as it sits right now, many people in their late 80's - 90's (not all I grant, but in my experience...) don't seem to be fully alive right now. They are often kind of half in and out of reality, and not at all the people they once were. They can't really contribute much (don't bother posting a link about a 90 year old who did such-and-such... it's a very glaring exception and we both know this). They take a lot of care. And, I can't imagine this is very pleasant state to be in either. If the state of aging progresses, but somehow death is forestalled, I don't see this being any advance at all, but rather one of the nastiest things that could be done for the human race, both old and young. It seems like forestalling death without solving the problem of aging (likely a much harder problem) might be very doable soon. And it is not a good idea. There are many evolutionary reasons for death. It's not altogether a bad thing.
