Quantity is not quality. Nihilism is a false philosphy. So many people nowadays suicides even if they have a lot of things and a "high-quality way-of-life", but they feel empty because they cannot find a purpose, a meaning, for their lifes.
I haven't say "we shouldn't make our lifes longer", we can make it longer but giving meaning to it: to not living just for living - we aren't animals nor plants - but to have a purpose. One can die young but happy, another can die old but unhappy. It's the death that give a limit to our, that make us say: "I have to live, I have to do the thing I want, to love the people I want to love, because after that day I'll can no more".
Look how many old people have the senile dementia 'cause they live more than they have should; medicine should heal this diseases first, I think; the death isn't a pity.
K, if thats what you think...
I make things because a. I enjoy it, b. I wanna know more and c. I wanna help humankind. I dont see death in this list. It might be subconscious but I dont see how it would change anything here. You say suicide. While I dont think its the right choice, when people say that suicide will rise when bio immortality will be introduced- I could say that it is an option for people who dont want to live longer and it can somewhat help with overpopulation. Suicide isnt the no.1 reason why ppl die, cancer is. If you say we should adress suicide I say we should adress cancer (or any other biological crap) first.
Edit (pressed submit by accident)-
Nihilism is a false philosophy- whats false about it? Does it have any inherent falsehoods? You cant just say that some school of thought is ''false''- nobody believes it because they are forced to, people find some of the core ideas to be true and continue to think like that later... you dont have to think like that but like anything in philosophy there's nothing wrong with it and some find it apealing because it represents what they think about life. Sorry for drifting far away from the main subject...
What you say sounds very religious to me. I myself am not religious because to me, a religion is just a bunch of people with some holy texts who try to give others a meaning for life, based on what they think to be true. Thats cool and all but even tho religious people might be happier (I think I read a study somewhere), not everybody who knows this fact is religious because for some living by the ideals that they dont agree with is worse then sadness. In other words, giving a false meaning to life (false here means something you dont agree with) is wrong, and wont help anybody.
About high quality etc- yes , money and power etc doesnt necessarily mean happiness, and while thats true, I think living in a non-poor society, where food isnt a problem, is better then the opposite.
About ''senile elders live longer then they should''- who said how long you should live? If its nature then you should die at an age below 50. Its the nature that gave people dementia. Nature makes some of us short- sighted, deaf etc. We can, and sometimes we do, fix those mistakes. We understand that tho nature gave this to us- we should not accept it as a present but fix it as a problem. We should fix dementia as it is a problem, not an indicator about how long we should or shouldnt live. Who cares about how long you ''should'' live. We should be the masters, nature done some great stuff but we shouldnt accept it's limitations.
The fact you live longer doesnt have to change your behaviour. You can live like a normal person until you're 40, 50 or 70 (as you wish, a good life, exactly like now) and when you ''become bio immortal'' then who cares what changes, everything from now on is just a bonus. If this sci fi future is so close, we *are* living a normal life rn, without knowing if we'll become immortals or not...
Then again, if you find this life to be too long or living too long to be wrong, you can always suicide after a certain age. Nothing will stop you from dying if.you really wish that. If there will be a pill you drink to become immortal and you dont take it when you are about to die then how different that is from committing a suicide after you take the pill?
Not gonna stop anybody from not tsking the pill- after all, when it will be avaliable, resources wont be so abundant...
