Aging may be a program, not a breakdown

    I've always thought eternal life would steal from the next generation if resources are scarce. If your reaction times, intelligence, etc are always good, and your experience and memories get better, it just seems like you'd out compete your kids and younger cohorts. All well and good but basically stops genetic turnover that got us to this point.

    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".

      OTOH a vast amount of mayhem and madness arises just from each generation's memory being wiped clean. Within three or four generations the earth lacks any sense of what risks came before it, and repeats the same stupid stuff.

      If we were managed by the interwar generation, little of what's happening today would be happening today.

        That goes both ways.

        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.

          Yep, it allows you to climb out of local maxima.

            Only if it works. Evolution works like this with local fitness maxima and wells of stability favored by entropy. You have to luck out with the right combination of mutations to not only get out of that well but fall into one of lower entropy. Imagine the size of the search space required for something like this. This is why evolution is "slow" in species that live as long as us and quite rapid in things that grow logarithmically by the hour.

          There seems to be a balance point with the number of Chesterson's fences. Too many and you are penned in or routed on one vector only. Too few and you are blind.
