[@MentalParadox]

I am a real, fully-funded cryonicist. Our movement has existed for well over half a century, and has about 2,500 members worldwide. Almost 200 people are already in stasis at facilities in Arizone (Alcor), Michigan (Cryonics Institute) and Moscow (KrioRus). Virtually all cryonics is done for purposes of extending life, the idea being that you are preserved until a possible date when the damage of whatever killed you can be reversed, but also the damage from the vitrification itself. It is not only for the "super rich" as the media loves to claim, and no Walt Disney is not one of us. It is also untrue cryonics almost always involves preserving only heads (neuropreservation). That service is only available at Alcor, anyway. My own contract is full-body.

[@quinnsmith8421]

It's refreshing to read comments that acknowledge that cryonics truly does make sense; the amount of people who I've heard say they're "intelligent and evidence-driven" who then ignore the evidence supporting cryonics just because it's positive is ridiculous.

[@MentalParadox]

@@quinnsmith8421 Most of their criticisms is because revival is as of yet unproven, but they don't get that that is exactly the point of cryonics. I have a friend who describes cryonics not as a solution, but rather as a "very slow ambulance, driving towards a hospital in the future".

[@luciferangelica]

say hi to fry for me

[@ravenlord4]

Two questions. First is that I assume that facilities have strategies in place for long term solvency. But if worse comes to worse and funds dry up, what happens to the clients? The second may be a chicken or the egg thing: are there efforts occurring to determine the legal status of a successfully revived client, or can that only occur after (or if) the very first client is successfully revived? Thanks!

[@quinnsmith8421]

@@MentalParadox That's a good way of explaining it. Whenever anybody tries to mock me for supporting cryonics, I ask for actual technical criticisms, which they never know how to do (because there probably aren't any), and when I point out that all of the evidence in the literature supports cryonics, it's goes in one ear and out the other.

[@Datan0de]

Cryonicist here who's actually attended and assisted with the initial steps of the process. While you didn't get into too much detail on the suspension process itself, this is definitely one of the better videos on the subject I've seen. The one point I would take issue with is in staying that cryonics patients are "dead". It's a semantic argument, but cryonicists often define death as "the irreversible cessation of life processes." If they can be restored and reanimated then they aren't dead. We can go a step further, though. Some would argue that you aren't *really* dead until your connectome has degraded to the point where the original neutral pattern can no longer be inferred. This is called "information theoretic death", and once you're at that point, you're gone.

[@quinnsmith8421]

Thanks for trying to clear up misconceptions about cryonics. Only a few person so far in this comment section who have mentioned that patients who are cryopreserved under optimal conditions are not dead.

[@Andrew-zq3ip]

I hope your book is a science fiction novel that seamlessly incorporates the ideas explored on this channel while fundamentally remaining a personal story about a cast of characters.

Watched it on Nebula earlier. Good vid, again you push these ideas to their logical limit and their impact on society. Something that is gravely missing in much sci-fi. Thanks for feeding my hunger for knowledge and my imagination.

[@sorcikator993]

It make me think of another book by Alastair Reynolds "Chasm City" (honestly one of my favorites by the author), where half the story follow Sky Haussman in the generational fleet toward a new planet. In this scenario, the "colonists" were all frozen, and the "crew" was there to take care of the ship and the colonists, generation after generation, never to go to sleep. SPOILER WARNING INCOMING. As time goes on, after the destruction of one of the ships, tensions between the remaining ships grew into what was described as a cold war, each crew becoming its own nation wary of the other, when they were supposed to be united. Even worse, Sky himself, to allow the ship he was now captain of, did the unthinkable: he shaved off weight from his ship by cutting loose cryopods, first of dead colonists, then of living one, crossing a line the other ships did not dare to cross. That allowed Sky to decelerate later than the other two remaining ships, giving him and the remaining colonists the "edge" that later gave the planet its name, "Sky's Edge", to claim the best territories. In the Reynolds Universe, Sky's Edge is to the present day, centuries later, still in a constant war resulting from this act. When you talk of cultural divergence in long interstellar voyages, sounds about right.

[@youngimperialistmkii]

When I was a kid and I first heard about cryonics, I was sure it was something I wanted to do myself. As I got older I kinda gave up on the idea. Now you have me considering it once again lol.

[@thek2despot426]

I say go for it. Consider the risks to the potential benefits. Is there anything to dissuade you from taking the chance to save yourself from a short life, to live for much longer, even indefinitely, and in a radically improved (and improving) world? Conversely, once you're dead, if the gamble turns out to have been wrong, you're just right back to where you would have been anyway.

[@procactus9109]

In reality it can't happen for long periods. Radioactive decay will destroy your cells beyond repair within a few decades. Robots to repair cells is a pipe dream.

[@Datan0de]

Go for it! Something I've found is that very often, unless someone you know is already signed up, there's a significant lag time between deciding to sign up for cryonics and actually doing so. In my own case it was a few years, and what really motivated me to finally do it was attending a panel discussion on cryonics at a sci-fi convention followed by a lengthy conversation with the participants afterward. My wife and a couple of friends signed up not long after me. The following year I got to be onthat same panel, and did so for several years afterward.

[@Datan0de]

@@procactus9109 Fortunately, it most likely won't have to. It only needs to keep you preserved and intact until we have the means to repair and revive you. Barring a collapse of civilization or equivalent catastrophe, this is likely to arrive within the next century, and some predict much sooner than that.

[@yastreb.]

@@procactus9109 Not in decades. Normal background radiation, including all sources, is only 2-6 mSv/year. Meanwhile 3 000 mSv is usually survivable with modern hospital care, so we are talking about hundreds or thousands of years.

[@quinnsmith8421]

@@francescodalo8828 The SENS spin-off company, Arigos Biomedical, the only research organization conducting helium persufflation research (for the purpose of creating reversible cryopreservation for organs in general) has recently run out of funds, so Aubrey has been thinking of helping to create an online crowdfunding campaign for Arigos to continue conducting the research, but he also has other plans that might not involve crowdfunding; he told me that he'll keep me posted.

i think the issue with zero metabolism freezing is the stopping of the electrical signal continuity in the brain, killing the old conciousness . the brain wiould create a new one that thinks its the original, but there is a break in continuity. a revived dead person would be like a teleporter clone, thinking it worked, while the original is dead. freezing a living person with signals being only slowed down to near standstill, insted of there being no congruent signals, could work though.

transferring the essence of a persons "id" or ego into an A.I. unit would be great . When it nears the end of it's life expectancy it could transfer to the next A.I. unit . Not gonna happen I know but trying to keep a human body going is a mute point

[@Antifag1977]

I would like to hear Mr. Arthur address the criticisms of using the Kardeshev measuring stick discussed over on the channel 'Unveiled". They proposed that better measures of how advanced a civilization is are Carl Sagan's 'INFORMATION MASTERY' and John D. Barrow's 'MICRODIMENSIONAL MASTERY'. . Rather than expanding to use ever increasing amounts of energy and matter - moving OUTWARD as it were, that it may make more sense for advanced civilizations to move ever INWARD. In the case of Microdimensional Mastery the focus is on having better control over ever smaller things until you have total mastery over atoms and spacetime itself as opposed to Kardeshev stressing mastery over ever larger things until you end up toying with galaxy clusters. . I imagine these 3 scales aren't mutually exclusive an in many instances will overlap. I don't see a K2 civilization not having gargantuan information processing power and I imagine that a K2 would also be quite adept at playing around with atoms if not subatomic particles and spacetime. I would love to hear Mr. Arthur address this debate since indeed it may make no sense for a civilization to even try to go beyond K2. I will include a hyperlink so that anyone reading this (hopefully someone who is able to propose it to Mr. Arthur or even Mr. Arthur himself).

Damage does not cease because you froze it, it only slows down untill reheated, such as by anything like a nanite moving nearby. Even if you manage to get it to near absolute zero with magically minimal damage, then the intrinsics radiation would accumulate and destroy everything, long before we have the tech to fix it. That said the damage caused isnt on the level of destroying a few water mains. Its on the level of crushing and tearing every single brick apart while keeping it in roughly the same place. The kind of nanotech required is possibly not clarke tech, but we will have nanites for tearing cancer cells apart for centuries before we get there.

[@qones3574]

Yeah, we need both robust scientific and cultural institutions for this to work. Given that there are currently frozen people today, I guess a win-win would be to help build that stable future, proactively.

[@WonkelDee]

Most likely you would wake up periodically. If you wanted to travel 100 years into the future you would not just sleep until the year is there, you would wake up every year, or every decade; that way you can be aware of current events and make the decision to go back to sleep or stay from there. On top of that, while you are frozen, you might be able to live in a virtual world for the time being, that way your brain stays functional, and you can be in a simulated world. Perhaps you would be able to communicate with the real world from there. It’s analogous to the theory that the first interstellar colonization ship would contain consciousnesses instead of actual humans. You can store them on the ship, and they can live in a life model decoy back on earth, mars, wherever they want, while making the trip. That would eliminate the psychological effects of space travel while minimizing risk, weight, cost, and much more.

In the Judge Dredd comic books if any criminal were to be mortally wounded the world be cryogenically frozen until they could thawed out so they could face justice for their actions.

I wrote a short story about a cycler style ship.

Cultural stasis might not be viable, even keeping some of the people frozen. With regard to that concept, you might have to ... let it go. 🤣🤣

How do you power these little bots?

[@virutech32]

most likely the same as naturally-occurring nanomachines are powered(ie glucose/fats/hydrocarbons)

11 of 29 months Percentage wise that's actually better than Canada. It's mid November and we will have snow for the next 7 months.

Isaac, being something of a futurist yourself- have you ever considered being cryonically preserved when you (legally) die?

[@eds1942]

Another reason would be to preserve and cut down the storage space for perishables like food.

9:15- was that a GOT dig? 🤣

[@matteolupo4034]

What about infinite tubes/rather not elevators(because it can't be connected to planets that orbit suns but could be near to it)/habitats stretching from a galaxy to another and making planets the "islands" and its inhabitants "islanders" because most people live in infinitely greater structures that connect galaxies and have glasslike exteriors to cover imported nature below from various planets(if other nature is found on planets) ? It can even be long and thin like highways of many connected asteriks * -> in 3 d like bacterias but with tentacles stretching in all the desirable directions [it could be built from all the lost asteroids as well as from a method(? does it exist?) to create matter from air (?) ]

[@johnkrappweis7367]

I am reminded of the anime “Gurren Lagann”. A species calling themselves the “anti-spirals” put their entire civilization into stasis to stop their evolutionary path towards their self-destruction and eventual extinction. Since any species that does not continue to grow and evolve is essentially already dead already, it was clearly a bad idea.

The top members of society would extend life. Things like e-sports (eve-online:Battle of M2) could be played over centuries. If someone wrote a booked based on the idea, could you do an episode? MMO e-sports cryonics

I was thinking of Xenos when you started talking about freezing in intervals.

[@SailorBarsoom]

Enjoyed this ep. Nothing unusual about that; I don't think you've had a clunker yet. I do, though, have a question about Curiosity Stream. My friend Tracy got me a year of it (with Nebula) for Christmas. I'm liking it, but... OK this question is going to make me look like a real dumbbutt, but how do I rewind? I'm watching it on my smart TV, and I can't rewind. Now that I try, I can't fast forward, either. What am I doing wrong or, what am I not doing right? A book you say? I'd be more than willing to look into that.
