Clarification
I always hear people claim that making people immortal would make life meaningless. I genuinely think this is a ridiculous viewpoint.
This post is long, and I've tried to format it to be as digestible as possible, as I feel it's all important to my viewpoint. Feel free to skim, or skip sections I use for comparison if it's too long for you, or you get my point already.
Let me clarify that I do not want to touch True Immortality (As in, you cannot die, and do not age) with a ten-foot pole. That is it's own special brand of Hell to me that would only be bearable under unique circumstances, and most, including myself, would not be able to bear it.
I am talking only about Biological Immortality, you do not age and COULD live forever, until you are killed, or even just until you choose to press the 'die' button. There needs to still be an option for an end, but it is not in order to grant meaning. It's only to give a way to end suffering if you want to cease, or a peaceful route to nonexistence if you're completely satisfied.
Because this is more of a philosophical view about the value in an endless life, I'm structuring it as an ideal scenario where people can just live until they choose to die. I'm still keeping the title as 'infinite' because some people could just choose to never die.
Useful Comparisons
I think the best description of my ideal world would be (Spoilers for the Good Place) Exactly how the Good Place ends. You could potentially live forever and do anything you could ever want, but eventually most people will be satisfied, so an option for nonexistence is a good thing. Yet others might find meaning in taking on an endless task, like Tahani seeking to master every skill and eventually becoming a Bad Place Architect, if memory serves. Obviously, this is an Afterlife scenario. But I see no theoretical reason an ideal futuristic world couldn't end up in a similar state, perhaps on a digital substrate if we crack true mind uploading without having any more doubt about the issues involved.
This is a more philosophical discussion than a practical one, anyway.
Sort of spoilers for Dark Souls, but it's nothing that's a 'reveal' or anything, they just kind of show up. This is pretty similar in my mind to how to avoid going Hollow in Dark Souls. DS3 has Undead like Andre and Patches who've stubbornly persisted since the beginning of the Undead Curse, because they never lose sight of the meaning in what they do and who they are (obviously being a blacksmith is a lot more productive and helpful than a backstabbing thief, but I digress.) Obviously, this world is far from ideal, and it's showing the strongest wills to persist through eons of suffering. But I still find it relevant.
I don't see why this wouldn't apply to real people, but I'm open to changing my mind, hence posting here.
Some Real World Context for Myself
I personally am someone who feels they wasted much of the start of their life scraping my way through school, and rotting away in the back room of my uncle's home for the entire 2010's, and that infuriates me. It doesn't add meaning to the remaining 40-80 years of my life. It only depresses me more and makes me feel like I'm more likely to waste more of it, losing even more time if I don't take care of myself properly.
I'm still in my first relationship, and I have been for nearly five years now, despite it being long distance and us only meeting up for the first time a few months ago. I'll finally be moving to her town in a year or so.
She has Multiple Sclerosis, and while it's something that is driving me to pursue my pre-existing interest in Regenerative Medicine, that does not make up for the sadness it causes me. Sadness that my time with her might be even more limited than it would be if we were both in perfect health.
It does not make that time with her mean more, the meaning is already there in every moment I spend with her, it was there in every moment before I learned of her diagnosis. It only tinges it with an extra looming dread that it's going to end, and if she lives a full and happy life typical of a healthy person, it only means that additional dread itself was a dampener on our happiness.
If I knew that my time with her would never end, that wouldn't cause me to squander it. The thought that I would just say 'Oh I can just talk to her next week, eh.' is utterly ridiculous. Every moment we spend together could be in complete relief that things are okay, that any small issues that come up are totally temporary. That there's no risk of anything important ever going unsaid, any meaningful discussions left unshared, even if it's temporarily put off.
If I was able to spend forever just developing the skills I want, just for the sake of doing it and for the sake of aiding others, then still having as much time as we want for our relationship; When both of us have explored everything that interests us, done everything that we want to contribute to the world, then finally, peacefully, choosing to die and see if anything comes next, I can't imagine any downsides to that.
Would some people waste their time if it was unlimited?
Yeah. Some people would, maybe a lot of people would, by my standards. But it's their right to find meaning wherever they find it. In this world where people have all the time they want, likely without a need to consume resources to have it, I see no reason they couldn't find real value in simple hedonism.
If they aren't hurting other people, does it matter? Who am I to judge them? Who am I to say that the value they find is false?
I'm a positive Nihilist, or an Absurdist, if that fits better. Life doesn't have any meaning to find, nothing is granted to us. We make it, and I don't believe there's any less meaning to make even if Life doesn't end. Allowing even those with an iron will who wish to persist endlessly and never stop contributing to find true meaning in that task.
Maybe someone just wants to be there to see the Universe experience Heat Death.
I don't get it, but they do.
Quantity has no baring on Quality, not on this, not in my mind.
Final Note
I've had people question my willingness to actually change my beliefs on my occasional posts to this subreddit before, because I go out of my way to provide a strong argument for my view.
I wouldn't be here if I didn't hold this view strongly. I do, but I recognize that there may be points where it fails. I do want to be right. But I love being proven wrong, having my views changed, because that then means I'm more right than I was before.
I hope the context in the previous section shows that my mindset towards life would only improve if my view was changed, that I could then cherish the limited time I have even more in face of the dread, so please do change it.
I'd also like to clearly state that AI was not used for any part of this post, every word and piece of formatting was typed by my hand, on the fly, in the past few hours.
I don't want those accusations poisoning discussion even if someone spots some random small similarity, and I know it's against the rules to make those accusations, but it still happens.
