    Cryopreservation is the best chance we have to bring back someone to life that we would currently consider (completely; no brain or heart/lung activity) dead. https://www.brainpreservation.org/large-mammal-announcement/

    That chance is way less than 1% of 1%, but grief makes us do weird things.

    Plus, perfusion needs to happen rather quite quickly or you get cell death on a scale that is likely to cascade, further reducing the chances.

    I’m considering cyropreservation, but only if I can figure out some organization that will do it AFTER all my donatable organs have been harvested to extend or improve lives. Denying my organs to the living seems too monstrous for how little the chance of “survival” is.

    And, while the structure of the brain might be saved, you are going to come back to a world that is unrecognizable. Either society can deploy nano-scale cellular repair for the whims of the dead, or we can upload consciousness. Maybe it’s better than non-existence, but I can imagine things that aren’t.

      Just curious, why would you consider cryopreservation after your organs are donated? I feel like you’d be a bit more difficult to bring back from the freezer if you’re missing organs. Or do you have another use-case in mind besides resurrection?

        I would be a “neuro”, so only my brain would be preserved. The current best technology for brain preservation would mean revival is either an upload, in which case I won’t need my body, or protein-level unlinking, a technology that likely means a new body can be created as well.

        Or at least, that’s my best guess. Certainly the amount of body-wide, but protein-scale damage caused by ASC seems harder to fix than regrowing replacement organs.

        Like I said, ASC might be the “best” chance we have, but the chances are very bad you’d survive at all.

          Tell me about the costs. What if it turns out to be just too expensive. What guarantee do you have they will do it?

            Well, I’ll be incapable of action or observation, so there’s always going to be an element of trust. For many people that means having their family or close friend observe the procedure and storage, maybe even “visit”. I don’t know exactly who I would ask to do that, but I have 3 candidates. The executor of my estate would have to sue for breach of contract if the service was not satisfactorily provided.

            Alcor has information about how they get paid: https://www.alcor.org/membership/ and I’m sure other providers also have similar information available.

            At one point, I thought Alcor provided “tours” for prospective members to show how/where they would be “treated” when they become patients, tho I don’t know how helpful that would be except to show they do have space/infrastructure to hold and maintain the dewars. I do think I’d want to see some details about the facilities before I actually sign up. I think some members are involved in patient care, which gives them confidence that when they become a patient they will receive good care from the remaining members – tho, that reasoning can come off a bit “cult-y”. As far as I know, there’s no standards / regulations that could be used to objectively judge the quality of cryonic preservation.

            I’m most familiar with Alcor, but I can’t say they will always be (or currently are!) the best choice. Their procedure is, last I checked, not what https://www.brainpreservation.org/wp-content/uploads/2018/02/letterofsupportforasc_kennethhayworth_jan2018-signed.pdf recommends. It’s similar, but as far as I know, NO organization has really turned ASC into something that approximates a medical procedure, and I haven’t gone on a research dive in Alcor (or any other cryonics org.) since the ASC won the brain preservation prize.

            HTH

                What is “this”?

                I’m not confident resuscitation will ever be possible (I believe I said “1% of 1%” in another post). It’s almost certainly not going to happen in 15 years (one demographic generation). If it is possible, It might happen in 150 years. We’ve only had integrated circuits for 65 years, so I really don’t have a good idea about what might be possible 150 years after my death.

                I do think ASC could become the procedure that is adopted by cryonics organizations within a generation. I don’t think cryonics will ever be very popular because it promises very little and has so far delivered even less. By the time that changes, we might not need cryonics much.

                I think the most likely future outcome is that under global climate collapse (before 2063, but after 2040) preservation of Alcor patients can no longer attract enough resources and fails, but so does the Internet, most large electrical grids, and industry regresses so that fossil fuels and most rare earths are no longer accessible, and the next Chicxulub event ends the homo genus.
