[1] Their risk of death does not increase after reaching adulthood. I.e. every year after adulthood has the same risk of unexpected death. Humans and other animals that age have their risks of death climb in "old" age.
OTOH, you'd accumulate uncurable disease, injuries, etc as well. Maybe you become a disease resevoir inside your own growing family. Or you pass on as-yet-unknown genetic anomalies that are unhelpful, and you do so forever.
Granted that's a modern take, and in particular a modern rpg-like take. Regardless though getting rid of oldies seems like a reasonable way to move a species forward if natural selection is driving "forward".
If we were managed by the interwar generation, little of what's happening today would be happening today.
Lack of experience is critical for risk taking. Even great successes like Jensen Huang have said that if they knew how hard it was going to be, he wouldn't choose his path again.
Memory blocks you from experimentation as much as it protects you from making recurrent mistakes. A species or civilization with too much memory will eventually wither away towards complete inaction and decay.
Maintaining order and fighting entropy is hard, but also planned obsolescence is a good thing for systemic resilience.
You have to regularly clear out the old for at least two reasons...
a) keep the process of creating new things well exercised. "We can't build that anymore. We don't know how." A factory that builds things that last too long eventually goes out of business.
b) prevent old things from monopolizing resources due to more time to compound interest. Otherwise, you end up with Saturn devouring his son.
A tree experiences compounding interest. The longer it lives, the more ground it owns and the more its tall branches and leaves blot out the sun below, making it extremely difficult for any juvenile of its species to take root and mature beneath it.
This is why some conifers have pine cones that only release seeds when burned in a fire. For these species, evolution has determined it's not even worth trying to germinate unless it's likely a fire killed its parents and made space for them to grow. This is part of how we discovered wildfires are a critical part of some region's ecology. We managed to halt most forest fires and it ruined the natural rhythm of life there.
Nothing is supposed to persist forever it doesn’t even make sense to try
"Supposed" by whom?
Each galaxy and any planets/life it contains are just artifacts of an "existence run." That's why life feels like a simulation so often (and human history repeats itself): we're inside of an organic (human word) "program" that's trying to perfect itself by running similar, but consistently tweaked "logic" over and over (a macro of sorts). Things like evolution are just an algorithm embedded in the system.
If the theory discussed in the article is correct, then aging is (in the scope of the above thought) just one program among several that we interpret as existence/life.
Just a daydream but fun to think about.
For example, if you go through some events in your childhood, they may stick with you until your death, as an inevitable part of you. Sure, treatment helps, but probably some memories you can't just erase.
Recycling things into a next generation, with probably better living conditions seems like generally pretty positive thing.
Also, some time you'd probably start to stop learning, not necessarily due to brain aging and neuron death, but simply because of basic architecture of our brain and how information solidifies and it starts to become more difficult to learn new things. We are a little more bored of most things and a lot of mystery and wonder diminishes somewhat.
There's been several articles over these last decades that have covered different iterations of genetic aging, and I think about that discussion every time. I wonder if she's read any of them and also thought about that discussion.
If we were managed by the colonial generation, slavery and segregation would still be the norm, only rich white men would be able to vote and a king would still have the final say.
The earth is a bad term here, how about human civilization?
Your DNA, epigenetics, and a ton of other subconscious intelligent processes are well aware of the risks and contain a massive set of tools to overcome them.
The problem? Many of these tools have to run from zero in an egg to work in the changing environment.
Doubtful. They were the ones who created the world we live in today.
On the other hand, always being around as a sort of Protector to protect your kids seems like it would generally be good for your genes. (Of course, you'd have to fight off other Protectors who are doing the same...)
He was in his 60s....
Once a parent, always a parent, I guess.
How this number is going to change in the future with exponential growth in the environment is left as an exercise to the reader.
But 1000 generations of unassailable, un-evolving, 40IQ lions doesn't get you to the galaxy.
Hey, maybe this is the fermi paradox.
This is the real feature of aging, death, and dying. Progress is measured in funerals, not years. If everyone lived forever, nothing would ever change.
Including our fundamental biology.
If we want a chance at improved, more resilient biology, aging and death have to be a part of that.
This is almost the stated intention of longevists.
I think we underrate the value of a fresh perspective. People living longer lifespans would dilute that benefit, imo. Sidenote: this is also an underrated issue with LLMs and their application to science - collapsing to single modes of thought over time.
birthing was necessary at least to maintain population, but preferably to expand it. it's only now that we consider "too many" a possibility, and we didn't evolve for this moment.
our history does not show potentially perpetually compounding gains that our children would evolutionarily need a genetic defense against, we already had looting, stealing, and killing.
I think the answer, if there is a programmed obsolesence, is because the genetic admixing of the next generation through sexual reproduction is so useful and important.
