Anyway, with climate change and population growth, "curing" aging is no guarantee of forever.
No one's suggested it would be.
Remove all "natural causes" of death and the average life expectancy wouldn't be infinity, it would be on the order of 1-2k years. Sooner or later accidental trauma or violence will get you, at least without other advances.
Still, that's at least an order of a magnitude more time to get what enjoyment one can out of existence.
If anything, it'll make those problems worse.
Yes, it will, at least at first.
Still, I'd rather have to fight for existence every day of eternity than be forever doomed by some biological expiration date.
Could it be done with the advancement in medicine, genetic engineering and biochemistry? Most definitely.
SHOULD it be done? Hell no.
Well, no one should be forced to accept more life than they want, but I'll consider any attempt to thwart my potential immortality as an attempt at my murder and will react in kind.
I wonder if in the very long term, it would be more painful to be eternal in the life than eternal in the death.
That life is more painful than non-existence is a given.
Life is suffering, but if I couldn't handle that, I'd have ended it a long time ago.
Another thought: All this life-extension concept may be seen as humans messing with and flying in the face of Nature. As history has told us, Nature has a nasty habit of biting us back when we do stuff that messes with "the grand design".
There is no grand design, just a collection interesting accidents.
If we had life spans so long it would be important to have something to actually live for. Plus, if you think we have a problem with over crowding, resource consumption and pollution now, just imagine if we were gifted with dramatically increased lifespans.
Just living is enough for me.
And no matter how bad those challenges became, I cannot imagine ever willingly surrendering my existence as a solution. If someone wants to put me out of their misery, they can try...whoever survives will have that much more of what's left.
