    Because this is the worst timeline, we're getting cell reprogramming used to grow artificial brains to run AI workloads before functional aging remediation... let alone GTA VI.

    Slightly tangential: Michael Levin’s work on bioelectricity and cell reprogramming is pretty interesting in context of emergent behaviors in groups of cells. https://en.wikipedia.org/wiki/Michael_Levin_(biologist)

    Sounds like the immortal jellyfish solution. We squeeze entropy out of our DNA by creating a new fresh cell (ovum) that’s very sensitive to genetic defects, meaning if it survives it’s probably good. The jellyfish just shrinks back to a single cell (presumably with some mechanism for keeping the ‘best’ cell) to reset the damage. This is doing the same thing, but piece by piece.

    Edit: And wow, that abstract appears to have eaten an entire thesaurus.

    It may be a dumb reason to do it, but recently I've started to focus on my health a bit more because of news like this (more exercise and healthier food).

    The thinking is, if we find a way to massively extend the human lifespan/reverse aging I want to live long enough for that.

    I'd be pissed if we as humanity solved aging and I die just before that, not taking any chances.

    kcarter80 4 minutes

    Seems like you are interested in living longer. One cool trick to doing that has always been to focus on your health. Are you saying that before recent developments the extension of life benefit wasn't worth it for you? By the way, when you die it's impossible to be "pissed".

    What if living 300 years meant the entire tempo of human living changes. That we all just slow right down because having control over our aging and when it happens. To be able to decide to extend your 20s… or not. To spend decades in your 30s. How would that change what’s important to us?

    They cannot survive the next 300 years unless we all survive the next 300 years. A dictator is motivated by having power over others, not being some lone survivalist fending for himself in nature.

    Walk me through it: in order to get dictators killed, because they defend themselves very effectively, we should put everybody on the planet under a biological death sentence, which will get the dictators too.

    No, I cannot endorse this.

    setr 34 minutes

    Science moves forward one death at a time

    So at least two systems run better with the implicit time limit.

    card_zero 31 minutes

    We should kill the dictators deliberately, improve our biology deliberately, and get stuffy old people like me to change their minds deliberately. No stupid use of death as a proxy, it's a horribly blunt instrument. "Let your ideas die in your place".

    Besides, maybe it's the young people who are the most dogmatic. Studies are inconclusive: https://en.wikipedia.org/wiki/Planck%27s_principle#Rebuttal If we're going to go around killing people for having rigid ideas, perhaps concentrate on the young ones, for statistical reasons.

    Wasn't death a requirement for us to reach this current stage of human evolution? I don't think it is a good idea to stop it entirely.

    Curing aging doesn't stop death entirely. There's still the attrition of living in the physical world. Some portion of the population will trip and break their necks every year.

    Everything we have witnessed that arises also passes away. Every living thing, every dead thing - even stars and planets - arise and pass away.

    I feel it’s the ultimate hubris to think we can cheat death.

    Moreover, why would you want immortality?

    Many books of fiction and poetry discuss the curse of immortality.

    Here are a few:

    The Immortal, Jorge Luis Borges (1947)

    A man discovers a source of immortality, but eternity eventually destroys the significance of individual experiences. When everything can happen infinitely, nothing feels particularly important.

    The Mortal Immortal — Mary Shelley (1833) - also wrote Frankenstein

    A man drinks an elixir and lives for centuries without substantially aging. He watches his wife grow old and die, and becomes increasingly alienated from humanity. Shelley focuses on loneliness and the psychological weight of endless time.

    All Men Are Mortal — Simone de Beauvoir (1946)

    An immortal man lives through centuries of history, relationships, and political upheaval. Gradually he discovers that even extraordinary achievements seem meaningless when time is unlimited.

    The Makropulos Affair — Karel Čapek (1922)

    A woman lives more than 300 years through an elixir. She retains her youth but becomes emotionally exhausted, cynical, and incapable of finding pleasure.

    —

    There are more. Sure, these are fiction. But use your imagination. Why would you want immortality, even if you could retain perfect health indefinitely?

    card_zero 16 minutes

    That is a really wanky, lazy, cliched, annoying trope - to a longevity advocate, of course. For the many people who inexplicably think death is friendly and wonderful, these tired old storylines are utterly insightful. (see also: Doctor Who, they did stories about immortality-seeking villains a few times.)

    Nursie 7 minutes

    Because one lifetime is not enough to experience everything the world has to offer.

    If one doesn't have to watch ones spouse, friends and family grow old and die, because it is available widely, that removes some of your objections.

    Personally I don't subscribe to the idea that things lose meaning in a longer life, I find it a 'just so' story of self comfort in the face of the inevitable.

    Not everything; only 93% of humans have died, for example. Past != future.
