Maybe you're right about that, although you're stretching it a bit with the infant mortality argument.
Really? It was the chief method of population-control once upon a time, much like death by aging is now. They seem pretty analogous in most ways.
People were "selfish" back then to not want their infant babies die. People are the same sort of selfish now to not want to see their parents die.
Lack of death in both cases causes the same sorts of problems, but people adjust to problems. Fertility declined after infant mortality dropped -- fertility per year will also be declined in people have their youthful years extended indefinitely.
Maybe you do think the latter but I think if immortality was discovered tomorrow it would be concentrated in the hands of a rich elite who judge their lives to be more important than the rest of ours. After a while it would be sold to those wealthy enough to afford it.
Do you understand that you just made two contradictory arguments -- before you said there will be overpopulation, because it will be given to all. Now you say it will be given only to some (so there's no problem of overpopulation), but these few will create an elite.
Those are two opposite problems -- which one do you believe will be the actual case?
These people would control the world through the generations and decide their own world order.
How does that follow? In what way does medical immortality give these people greater powers of control than any current or medieval non-immortal dictator or monarchical dynasty?
Well actually I think you misunderstood me. The statement you're basing your argument on is "Death isn't a problem to be overcome it's the natural conclusion to life." I admit that I may have "imbued the word natural with moral weight". However you are responding as if I had said "death is natural therefore it is desirable" which I did not and which would be a pretty meaningless statement to make. I merely used natural as an adjective, I could have used "inevitable" or "only" or many others instead. The adj...
If you don't believe in an afterlife, then it seems you currently have two choices: cryonics or permanent death. Now, I don't believe that cryonics is pseudoscience, but it's still pretty poor odds (Robin Hanson uses an estimate of 5% here). Unfortunately, the alternative offers a chance of zero. I see five main concerns with current cryonic technology:
So I wonder if we can do better.
I recall reading of juvenile forms of amphibians in desert environments that could survive for decades of drought in a dormant form, reviving when water returned. One specimen had sat on a shelf in a research office for over a century (in Arizona, if I recall correctly) and was successfully revived. Note: no particular efforts were made to maintain this specimen: the dry local climate was sufficient. It was suggested at the time that this could make an alternative method of preserving organs. Now the advantages of this approach (which I refer to flippantly as "dryonics") is:
There is one big disadvantage of this approach, of course: no one knows how to do it (it's not entirely clear how the juvenile amphibians do it) or even if it would be possible in larger, more complex organisms. And, so far as I know, no one is working on it. But it would seem to offer a much better prospect than our current options, so I would suggest it worth investigating.
I am not a biologist, and I'm not sure where one would start developing such a technology. I frankly admit that I am sharing this in the hope that someone who does have an idea will run with it. If anyone knows of any work on these lines, or has an idea how to proceed, please send a comment or email. Or even if you have another alternative. Because right now, I don't consider our prospects good.
[Note: I am going on memory in this post; I really wish I could provide references, but there does not seem much activity along these lines that I can find. I'm not even sure what to call it: mummification? Probably too scary. Dehydration? Anyway feel free to add suggestions or link references.]
