    Plenty of meat bags walking around now without a fully functioning brain. Can we use those?

    There’s a trick most of the population can do to “youth up”. Rewind decades of biological age for your entire body. The answer is out there. Start with the jungle people that even in old age have hearts like 20yr olds.

    they tried that a few years back via a quadraplegics brain transplant to a normal body. he died on the table. not likely to change that with cloning

        They might have confused it for a head transplant?

        Although neither patient was alive at the time of the transplant.

        I don’t know if a full brain transplant would be feasible, or even a good idea. Not only would none of their senses and motor nerves work for weeks while the brain and nerves re-established themselves, but they would be walking around in a dead person’s face, body and speaking with their voice. That seems genuinely horrific.

          I cut a big nerve in my thumb years ago, and apparently plastic surgeons fix that sort of thing.

          They reattached the nerve bundles, but I was told the sheathes could be realigned, but the nerves would have to grow back from the point of the cut all the way to the skin.

          At first one half of my thumb was entirely numb, and over the course of well over a decade I’d get pins & needles as bunches of nerves would finish regrowing, except attached to random channels in the nerve bundle, so my brain had to completely remap all those signals to what they actually meant. Also extreme nerve pain near the cut whenever it was bumped, I assume because many nerves just didn’t grow successfully and remained near that site.

          It felt super weird because hot, cold, pain & touch were all mixed up, but eventually my brain sorted them out. It still feels a little weird, especially near my nail, but I haven’t had a pins & needles experience for a few years.

          The problem with doing that with a neck is that it would take wayyy longer and the chances of the patient dying from complications due to no brain signals working right… yeah I don’t see medical science fixing this unless we can regrow nerves in a much shorter span of time.

    Good lord, just let people DIE. Imagine what a rotten place this would be if people with outdated mindsets continued to control the world decades or even centuries after their expiration dates. People were already angry about 80 year old presidential candidates… what happens when they’re 120, or 150?

    If you want a bit of a deeper dive, Sean Carroll’s Mindscape gets into the science of aging and known workable remedies/treatments.

    The good news is that Billionaires will not be living forever any time soon.

    The bad news is that we’ve got a cellularly defined terminal limit and there’s nothing we can do to simply reset the clock. “Cloned Bodies” for animals are dysfunctional bordering on nightmarish. The human brain’s plasticity isn’t something you can renew with a pill or a potion. Blood Boys don’t work. There aren’t trivially replaceable components in the human body.

      That’s nothing to do with the back that clone is impossible and just that cloning is hard. You are acting as if it is an unsolvable problem.

      Its wild this research is even being attempted, its borderline unethical to experiment on otherwise healthy people.

      I fully don’t expect immune system driven aging to be understood until the Thymus better understood. DNA reproduction and telomere related aging will not be addressable until cell to cell signaling is finally mapped, and methylation activation/deactivation can be targeted.

      Most likely some kind of cloned brain tissue can help reduce age-related cognitive decline and some diseases. Imo we’d get far more out of targeting specific diseases than going after aging.

      I’d be fine with billionaires getting it first. As much as I’m not a fan of late stage capitalism, I refuse to cut off my nose to spite my face; they got A/C, feather beds, cars, baths, and all sorts of other luxuries long before us plebs got them. Let them beta test the stuff, and by the time the economies of scale pick up enough for it to be affordable to the rest of us, the kinks will be worked out.

      Of course there’s always the possibility of a cartel withholding it from the masses, but that’s what the second amendment and guillotines were invented for.

        I doubt it. They will just dump shit further away. If their solution default is to make things “somebody else’s problem” there’s no reason to believe they will stop thinking that way.

          That might be their outlook on “local” pollution for a while, but you don’t think going from 20 years left to centuries to live might affect their opinions on global climate change?

            Not really. Many of them are already heavily invested in life extension tech (not that I think it will work, but it means they’re optimistic). I think their general worldview is that technology will fix it, at least for them.

    President Joe Biden created ARPA-H in 2022, as an agency within the Department of Health and Human Services, to pursue what he called  “bold, urgent innovation”

    I did not see Biden creating a cloning and immortality medical research arm of the government but I guess it’s proof he already knew he was getting old before the debate and no wonder Trump wants back in the white house.

        If they’re functional, and we get serious about space or birth control, then no it’s not a problem. But that is another path we can take to really juice the dystopia.

          It will take a very long time indeed before we can reach another habitable planet enough to alleviate an exponentially growing population, and forced birth control will be unpopular, not to mention probably employed as eugenics by those in power against those who aren’t.

        … and reduce emissions by wasting the rest. But due to negative selection leading into that upper class they won’t be able to manage the planet further despite thinking that they can and will die of hunger eventually.
