1.Many industrialized nations are now actually near zero population growth.
You're implying that...?
2. People who can develop the technology to beat natural aging will have long since developed the technology to colonize space and have practically infinite resources to support human life.
Why would it happen in that sequence, specifically, in a few brief examples?
However, I don't think we will beat aging or colonize space, human nature being what it is.
Fine, we nuke ourselves. Nothing to argue in that dead end. The curious thing here is hearing people's excuses for denouncing a cure for aging.
Living forever as I am now would not be desirable. I'm young, healthy, and have a pretty good life btw,its just that I can see in myself the flaws in human nature, the "original sin" if you will that would make eternal life unbearable if one didn't have a *better* life to look forward to.
So you couldn't live with yourself as you are now. Why would (say) 500 years not be enough for you to allow you to make yourself a better life?
Human population already has a tendency to expand to the breaking point of resources, and mortality is the only significant downward pressure on that expansion.
IIRC the first world countries are already pas that peak. People would still die from train wrecks and terrorism (assuming that hasn't changed), etc. Technological progress increases the available resources, increases efficiency, and economics correspondingly adjust supply and demand. How do you justify that a world population past the growth peak, with enlarged resource bases, increased efficiency, and that's made of people who've had longer to learn and therefore have higher skills on average, would run out of control demographically? Speaking of which, such an increased lifespan would go a long way to help space development, rather than not.
Without mortality, even one child per couple would cause a cataclysmic population expansion.
Mortality would still be there, just not from aging. Or not for (for the sake of argument) a couple hundred years. People wouldn't have as many kids as often. e.g. Life would be more valuable, when you have a couple centuries (invested in the past, to look forward to in the future) at stake rather than a couple decades.
You really don't understand that if people stop dying we will overpopulate this planet (even faster than we already are)?
I addressed this above in reply to Anax. I understand and can entertain what you're saying, but want you to articulate exactly why I should agree.
People won't stop having children without extraordinary measures.
Why wouldn't dictators in the third world cap them the same way China's done in the past? Why would people spoil their increased lifespan for themselves by having kids? But fine, extraordinary measures. If that's what happens, why is it such a big deal as to make ridding ourselves of aging unattractive? Can you reasonably argue that once it's possible, there won't be a push to make it accessible for everyone? That the same ridiculously large social programs we have today won't be all over this one?
Only the rich 1st worlders will have the education and means to profit from such technology. The poor 3rd worlders will not "live forever". If I live 10 normal lifespans I will consume the resources of 10 lives. Invariably the poor will suffer when the needs of the rich are not met; if an overpopulated 1st world grows hungry we will take from the 3rd world... Like we always have.
Why? How do you see governments not making this available to everyone? How would such a huge portion of the human population stand for such an injustice? Explain this to me. "Like we always have" sounds like pessimism.
You can't see these extremely obvious ramifications of immortality?
I can see them (again I'm talking about centuries long lifespans if not indefinite, not immortality) and am curious why they're denounced as negative, or why people would even oppose them. You want to die after a couple decades, that's fine, no one's stopping you.
We need a return to ancient virtue: dying well is more important than living a long time.
Can you explain why they're mutually exclusive, why living a long time would lead people to die less well rather than better?
I think technological immortality is such a pipe-dream
Sounds like demonstrating this is child's play. Can you?
