Reply to comment by ting_bu_dong in How Death Can Help Us Live: a philosophical approach to the problem of death by simsquatched

But we can make a car Last forever , always replacing an engine, drivetrain etc. same cant be said for humans because we arent keeping humans alive 200+ years. its not a problem we can solve. But again Death in itself is not a problem. Its part of Life, we need Death.

Yet.

Which is why we need to continue to focus on the problem.

Well we won’t be able to solve death entirely because of entropy. I think most of the research now is on extending healthy years.

Realistically entropy will only start to become a problem in a few trillion years, and even after the last star dies in a 100 trillion years there are many feasible (and relatively low tech) ways to harvest energy from black holes.

I don't know about you, but I'll start worrying about the technical differences of a few trillion years and forever when I get there.

I’m pretty sure the breakdown of the human body due to aging and wear and tear would lead to organism death well in advance of trillions of years.

Even the elderly consume the same amount of energy as the young but just eating can’t extend life forever.

Entropy is at work at all times to move systems from highly improbable states like human beings into highly probable states. It’s very much a problem.

It’s at work at all times. It only needs to work once. This is why magic is impossible and why the hard problem of death will never be solved.

Heck even computer systems degrade with time if you wanna go the human consciousness in computers route. Entropy defines the limits of the possible.

This break down of the body is something encoded into our DNA, not something dictated by the nature of reality. We have found life forms on Earth that appear to be biologically immortal and can continously regenerate themselves, seemingly without end as far as we can tell.

>Entropy is at work at all times to move systems from highly improbable states like human beings into highly probable states. It’s very much a problem.

Entropy only necessarily increases in a closed system. The human body is very much not a closed system. As long as there is other entropy to increase (such as from un-fused hydrogen or un-evaporated black holes), there is no physical reason we cannot keep the entropy of a human body low over very long time periods.

>It’s at work at all times. It only needs to work once. This is why magic is impossible and why the hard problem of death will never be solved.

Again, only in closed systems. If you spill milk on the floor nothing is physically stopping you from sucking it back up into the carton. Though the action of doing so will increase the overall entropy of the universe, even if it decreases the local entropy of the milk-carton-floor system.

>Heck even computer systems degrade with time if you wanna go the human consciousness in computers route. Entropy defines the limits of the possible.

I mean, if you never repair the computer (which you totally can, no magic needed I promise), sure they'll degrade over time.

Alright, you’ve satisfied me that you know what entropy is at least. I jest, placating gesture.😅

I decided to look into these immortal organisms, and none of them are truly immortal. Even the regenerating jellyfish have been observed to fully die source. Tardigrades too. Even you wrote appear and seemingly.

Animals can extend life through various means, but not forever, organisms aren’t built to last, species are.

>encoded in dna not nature of reality

I regret to inform you that dna exists in reality so it absolutely is bound by its nature. This can explain how copying mistakes are made, etc.

Even certain animals without telomeres can’t live forever.

Aside from all that, predation, disease, and injuries are also related to entropy and the nature of reality.

To your point about causing other entropy to increase in order to decrease our own, that goes to my point about eating.

Even the highest quality foodstuffs can’t reverse the aging process, no matter how much energy is pumped in. This has to do with more than just telomeres (although I addressed those already). Aging is a complex process that needs to be further understood.

I’m optimistic about the future of aging science and technology also, we should shoot for the stars! But we should be pragmatic about the realities of being an organism.

We do not need death. One could argue that, under the right definition of “need,” that is an outright contradiction. Even an unsolvable problem would still be a problem.

An additional benefit of longer life would be that, given a longer lifespan, individuals are naturally gonna focus on more long term priorities

Our species used to need death to evolve (death means more birth which means more genes mutations). But today, there's no longer a survival pressure that make our genotype evolve (yes there is a reproduction pressure still but it's doesn't make us evolve in an interesting way any longer).

So it's say that, no we no longer need death today

Death also isn't needed for evolution, only varying amounts of reproduction between individuals.

Specifically, death by aging is likely an unintential outcome of evolution, rather than something that evolution needs in order for it to happen. I can get into the mechanics of how aging likely evolved, but it is a bit a biology lesson.

I would also hesitate to say that we have stopped evolving in "interesting ways" (whatever that means). Evolution happens on a very slow time scale and I do not think anyone has a good handle on what our current environment most selects for or how strongly it selects for it. Seeing how it is difficult to point to any evolutionary changes in the past 5,000 years (a vast majority of which were before modern medicine and food production techniques), to say definitively we have stopped evolving in the last 50-100 years since the invention of antibiotics and vaccines and adoption of modern agriculture is jumping the gun a bit.

Especially since it isn't like we've totally eradicated untimely deaths (that is to say death before reproduction). We still have 3.1 million young children dying of starvation and 5 million dying of disease each year. Even ignoring deaths among older children/teenagers, we are losing over 1 person in 20 before they have a chance to reproduce.

Even ignoring the modern death rates among young children and babies, there is still a great discrepancy in birth rates among individuals and that is what evolution actually acts on. An adult who made a conscious decision not to have children (an increasingly common phenomenon) is just as evolutionarily unfit as a baby who died before their first birthday.

For a population to be truly evolutionary stable it needs to be infinitely large (8 billion may approximate that), each individual must mate randomly (definitely not true), and there must be no selection pressures (unlikely, as I layed out above).
