JD,
Your points are good, but i think they're your perceptions, not the reality you claim since immortality doesn't occur.
Eh? Perhaps there's been a miscommunication, and I wasn't clear in my phrasing. The reality I refer to is the findings of psychology/psychiatry and the physiology of the brain -- as far as I know, no, there isn't anyplace immortality has taken place (then again.....
). All the indications are that the brain really does have a limited capacity for storing memories and experiences, and that, the closer one comes to that limit, the more partial and spotty the memories become, finally getting to a point where they aren't retained at all. And, again, the psychological factors enter in here, as well, in that, as experiences become repeatable, they begin to lose their novelty-value, and can (and eventually do) become dull, even feeling like a punishment eventually. Anything will take on that cast given long enough, no matter what it is. That's the way our psychology works. An eternity of experience (as opposed to a prolonged existence) would inevitably have that effect, as there's only a limited amount of experience that the brain would be able to take in, and the more experiences, the more one begins to see similarities to other experiences, as well, until eventually (though in exploring the universe, etc., this might take a tremendously long time) they simply become too similar, and lack enough contrast to excite interest. As I say, there may be the very rare exceptions, but look at the figures, and you'll find this is true for the vast majority of human beings.
As in most circumstances, people make their own "hell" or "heaven." I've seen people living in terrific places bemoaning the fact that they have to live there and i've seen people live in lousy places and finding it wonderful. My point here is the concept of the self-fulfilling prophesy. If you expect it to be bad, it will be bad.
There's certainly a fair amount of truth to this. People can turn a paradise into hell in their own mind, and vice versa (within limits, of course, especially for the latter -- if you're in a plague zone, or surrounded by death and destruction on a massive scale, the only way to turn that into a pleasant place is by use of some form of severe denial of reality, becoming delusional; but of course those are the very, very extremes). But there comes a point where the effects of the pain around you cannot be fended off without recourse to something of that sort, as the world situation worsens (which it is likely to do, as people will continue to breed, and with immortality, you'd end up with even worse population problems, or enforced sterility -- neither of which is a desirable outcome).
You state that existance would become a burden. That death is the goad to grow. There's nothing to support this view. I certainly don't accomplish the things i've done because death lurks in my future.
Again, this is supported by an enormous amount of research in psychology. It is almost never on a conscious level, granted; but that goad is there, nonetheless, as death permeates our worldview, however much we shut our eyes to it ... we're aware of it from a very early age, and we're surrounded with it every day -- the newscasts, friends and family members that die, or hearing about it from neighbors, friends, schoolmates, etc., etc., etc. It isn't a negative thing, as it prompts us to strive to improve things in so many areas, from medicine (where it most certainly is the major incentive -- the desire to conquer death and the illnesses that lead to it) to exploration (perhaps even to the stars), for
lebensraum because of overcrowding and the danger of starvation, etc. It, along with the sexual instinct (which, it is often argued, is closely linked to this on the most basic level as the instinct for survival, even if only through progeny) powers vast amounts of what we do: Improvements in our hygiene, improvements in our foods and food preservation.... all stem from a desire to prolong life ... and what is that but a fear of its opposite?
As for the "world without children" -- I apologize. I misread your intent on that post. However, there we run (once again) into the problems with population pressure, and the impact of that on resources, and the social impact of that, including increasingly draconian measures concerning childbearing and child-rearing.
There's also another aspect that's not been discussed. I see a lot of talk about doing the things we want to do, whether it be exploring nature, travel, going to see other worlds, etc. ... but how is that to be financed individually? Doesn't that mean continuing to work indefinitely? While there may be quite a few who truly enjoy their jobs, anyone out there think that they'd like to stick with that job forever? And if not ... again, you've got the competition growing as the population grows (and while immortality may be voluntary, even if it has disastrous effects as I predict, people will take the chance, and the population will continue to skyrocket). Not to mention the fact that automation will (even if we stopped having children today) increase at least for a good while, and that's going to eliminate more and more ways to earn an income, as the machines become better able to provide any goods or services than people, more quickly and efficiently and without all the necessary benefits packages.
Again, I stress that I am not denying the attractions of immortality; but I am arguing from a more realistic viewpoint based not on the existence of immortality, but extrapolating the effects from the known psychological/emotional makeup of the majority of human beings, and our history, and how very poorly we are equipped emotionally to deal with even mild boredom, let alone the kind that most people would experience with immortality. Let's face it, the vast majority of people are extremely limited in imagination, even in being able to entertain themselves (partially the fault of lack of nurturing that quality in our educational system and often at home, but also largely because the majority simply lack the ability to stretch their imaginations, and are frankly disinclined to try) ... can you imagine what would happen with that problem being compounded by an
eternity of boredom?
I am sure that there are strong-enough-minded individuals to enjoy an immensely prolonged lifespan,
if they are allowed to live it freely. But I'm afraid that
anyone would eventually reach a limit on this, if we're talking true immortality. (Longevity is another thing.) And in the meantime, we aren't isolates; we interact with our societies, and that interaction would play an enormous role in how enjoyable such a prospect would or would not be.
Has anyone thought about this aspect of it: All the nations we know now are relatively young, from the point of view of our existence as human beings. Even the oldest is only a few thousand years in age. The vast majority are considerably younger. America is, of course, only roughly two centuries in age (three-and-a-half, if you go back to the landing at Plymouth, for the current predominant culture). Now -- how much longer will any of these nations be around? Some will not last out the century. Most will not last the next thousand years. Nations are, by and large, precariously stable things. While it might be fascinating to watch the changes, how many will care to live through the changes, in the thick of them ... especially if their nation is one that no longer exists as such? And that is only one aspect to consider.
At any rate, I think I'll withdraw, as I've filled up far too much space as it is. It's a good discussion, and I may pop back in now and again; but it's time I shut up and let others speak, I think. (Looking back over this post, I'd say it's long
past time!) However -- for the aspiring writers out there, I hope that both sides have provided food for thought, so that anyone interested in writing a story on the subject has had their imagination stimulated to start extrapolating and giving serious consideration to what the implications of such a change would be. The better thought-through this is (whichever direction you decide), the better your stories will be; the more thought-provoking as well as more entertaining....
