Ok...when does this 'anti age' thing start. NOW? So all the useless babies will STAY useless babies forever?
You can't GROW without food, so if we didn't eat we'd be pretty much stuck exactly as we are.
You REALLY want a generation of people who never grow up? And pretty soon the earth would be covered by squishy, crying babies nobody wants. You'd have the current population of adults, and all the never aging infants we produce.
And these kids would never intellectually age, either. So really...useless.
Aaaaand all the people who can't deal with the kids, they spend eternity torturing a baby they don't want? And the kid spends an eternity being ignored and abused? Being immune to physical pain doesn't mean you can't be scared or emotionally hurt.
I can just see people throwing their 50 year old squalling infant against the wall and kicking them around like a football.
I would imagine that it would be alright for the first few hundred years. Eventually, though, I have to imagine that it would become amazingly boring going into the first few thousand. of course I would hope that we as a race would begin to explore interstellar travel. That would definitely add a few thousand more years of entertaining experiences. Still, in the end I have to imagine that it would become amazingly boring and ultimately lead to existence being torture. Who knows, it would be nice to be able to read everything I'd like to read.
Finally we will get into space. If we are immortal we don't need suits, protection, food, water, oxygen, heat and we will have all the time of the world to reach other systems and even galaxies.
If you mean not dying of old age or disease, the answer is pretty much the same. But we would need things like a space elevator, ships, stations and bases. But we would have plenty of time to invent and built those.
If death ceased to exist the biggest problem would be overpopulation and running out of resources to feed and house a growing population, eventually all the world's resources would be used up and the planet would be choked to death by an overabundance of Humanity.
No one would have to worry about starving to death because in your scenario that threat has also disappeared, but eventually all the world's plants and animals would be eaten or destroyed, the delicate balance of the food chain would be broken and the world would die anyway.
But then, considering aging has also been stopped in this scenario, would it be possible for new children to be born at all? The fertilized egg needs to age in order to begin dividing up into the cells that will bring forth a new Human; without aging the egg will go no further then the fertilized stage and eventually get flushed out during the woman's cycle. No more Humans would be born. That solves the overpopulation problem.
But the world is overpopulated as it is right now and it struggles to sustain us and the other life on its surface; the only good thing I could see coming out of immortality is that perhaps with more age will come wisdom in our race and we'll learn how to work with nature to benifit our world instead of against it.
It would become overcrowded. The natural world would probably disappear in order to make way for the human populations. Or humans would start enforcing no-reproduction rules which would lead to emotional suffering for those who wanted to have children.
Maybe we'd escape it by finding other worlds to populate, probably destroying this one in the process.
Let's see... We've fought wars of national supremacy [The World Wars, just about any colonial war] wars of ideology [The Crusades, several of the Cold War proxy wars] wars over non-critical resources [Opium Wars, arguably the current Iraq/Afghanistan]...
National supremacy was for resources and shit, though, which we presumably don't need any more. Ideology wise, I'd say ideologies are driven by wants/needs. It sounds like from all this, we won't have any.
I'm sure we'll still have wants. And some of the "resources and shit" we've fought over definitely weren't necessary for survival. I mean. Spices. Silk. Precious stones and metals. We don't need those to live unless you're convinced that your survival depends on being more pimped out than the guy next to you. Which, admittedly, some people at the time seemed to think was the case, but I suspect that they believed it in the same way that half of Politics Forum thinks they'll die if you take away their guns. Probably they won't die, but it's convenient for them to believe they will.
Can people still reproduce in this scenario? If so, complete over population would be an obvious consequence. Of course, since people can't di,e I am not exactly sure what the result of that consequence would be. Can you still suffer mental and psychological damage in this world?
So overpopulation is an issue in the sense that people are immortal but can't have children? In any case: Con -It screws up our evolution, so we would forever remain as we are. -Likely will experience everything there is too experience in life and eventually get bored. -Depression on a massive scale (maybe) -Learn everything there is to know about the world and the universe, and possibly get depressed because there is no more mystery to be had.
Pro -It screws up our evolution, so we would forever remain as we are. -You won't need to save for retirement, or retire. -Be able to experience everything there is to experience. -People won't have anymore reason to go on about God and the after life -Learn everything there is to know about the world and the universe, without relying on generational knowledge.
Sure, as long as you respect that this is entirely my opinion. Don't want to start a fight (which is ironic to hear from someone entering a forum based on religion)
In our limited, Earthly lives, we all know we're going to die, so we try to make our lives as best as can be. We learn valuable lessons as we age, which wouldn't be possible in an undying world.
Where life is eternal, we would have no reason to want to do anything, anytime, because we would know that time is unlimited and we will always have a chance to do something, whenever. There'd be no such thing as hope, faith, or religion because there would not be death, or the mystery of where to go next. We would not have to worry about finding that one special someone, or going to once-in-a-lifetime events, because such things would not exist.
In only a few generations all biomass on Earth would be locked up in the form of human bodies, forming a layer of solid human flesh across the surface of the Earth, host to trillions of human minds all suffering the agony of sores from all the chafing, being crushed beneath the weight of the population above, and also starvation and/or being cannibalised.
as stated in the original post, pain is impossible in this world. Humans have been rendered unchangeable on a physical scale.
The idea that humans would allow reproduction on that big of a scale is silly, but would make a fascinating story. Plus, if people couldn't age, it would stand to reason that anyone born in this world would stay trapped in the body of an infant. China has population control. So would this world. Maybe.
But how is that a problem? No one can die. They can't starve or become malnourished. They can't age either. so any infants that are born will stay infants, assuming they can even be conceived in a body that is perpetually unchanging.
