Patri, on odds see my latest post. For a lower price, see CI.

Ebonmuse, I find the trail-for-crimes scenario pretty unlikely. But if that happened, well wouldn't it most likely be a good thing to make myself available to stand trial?

Hopefully, the gains to med research from donated brains are pretty small. I actually doubt most get used.

Mitchell, that could add some value, but at a pretty large cost, so no I wouldn't bother.

Kaj, yes, we seem to see a lot of far-thinking rejection, which wouldn't translate into near opinions.

Eliezer: However, this only equates to the question of whether you would spend $28,000 to avoid certain death.

But it isn't spending $28K to avoid certain death, it is spending $28K for a small shot at avoiding death. And that's very different. That $28K can do good things for the lives of people I care about - like my kids. If it's a 1% shot, than I am taking $2.8M away from my kids to live instead of dying. I don't know that I have enough money for that to be a good deal.

And the insurance funding takes money out of my pocket in the worlds in which I live a long and healthy life and don't need cryo, because the singularity comes first.

Also, $28K? Alcor's FAQ tells me at least $150K for whole-body, and $80K for head-only.

Robin: Patri, when considering the cost of financial payments, you must weigh both when they happen, and in what state of the world they happen. Cryo costs are low until the time and state in which you would have died, at which point you likely have no better uses for your money, at least if not much poorer than I think you are.

What do you think the odds of revival are? There are lots of useful things I can think of doing with my money when I am dead, that matter to me now. Cryo is expensive - Alcor says $80K. If we are optimistic and think revival is 10%, that's $800K to live. If it's 1%, that's $8M to live. I value my life at somewhere in that range, so it really matters to me what the odds are.

BTW, I find it kind of baffling that I am a cryo-resister because I disagree violently with pretty much every anti-cryo comment I read here on OB. When I hear things like There is no "reason" why I want to live except that it is hardwired into me by evolution, the same way the sex drive is hardwired into me. I roll my eyes and laugh. Yeah, there is no reason for a nihilist to sign up for cryo...or to ever do anything else in life, so, whatever, let's move on to those of us who have goals and motives and believe life matters.

@Ebonmuse: I think the main point is that any scenario in which corpsicles are being revived is unlikely to be very bad. Obviously civilization has not collapsed if they have this advanced technology. Presumably they are likely to be wealthy as well (again due to having advanced tech). Also, probably a society that would bother to revive 21st century cavemen like us is either trying to learn something or trying to do something benevolent and altruistic.

Or maybe they'd be reviving us so that they can put us on trial for the crimes committed by our era. I think that's actually a fairly likely scenario, if we take our baseline plausibility level to be the probability that cryonics works and frozen people can be successfully revived.

If future society is really bad, the chances of revival from cryonics is non-existent. Any future society that can revive us will be, by definition, an advanced technological society. Now, such a society could be dystopian, but I think any such dystopian will be more like a cyberpunk SF novel than anything like "1984". The key benefit of the dystopias depicted in cyberpunk novels is that they have considerable energy and diversity. This means that even if society is screwed up along these lines, we can still do things to create the lives that we want, regardless of the external conditions. I could most certainly create personal happiness in any of the societies depicted in cyberpunk.

Ebonmuse's criticisms of cryonics (and of life extension in general) are very typical of someone who views them self as a passive participant in life. One who views them self as a hapless victim of life events.

If he actually spent time around cryonics and life extension people, he would find that many of us do not share this world-view, nor do we live by it. Many of these people are activists and entrepreneurs who take a active do it yourself effort to create whatever lives they want. This is much like the do it yourself spirit of the original immigrants who built up the U.S. Analogous to the immigrants who crossed distances to come to the expanded opportunities of the new world, cryonics people seek to immigrate across time to pursue the expanded opportunities that a future society will have to offer. Any sufficiently advanced technological society that can revive people from cryonics suspension will, by definition, be one with far greater opportunities for the individual that present day society.

I can tell you that, if we make it, we have no intentions of being passive victims of future society. We will do whatever it takes to create whatever lives we want for ourselves, come hell or high water. Failure is not an option here.

What do you all think is the population split between the amount of people we want cryo preserving themselves, and the people we want donating their brains to brain banks for medical research? 1% vs. 99%? I'm aware of various easy outs one could take to avoid the question ("So few people are signing up for cryo that the question is mute") -I'm curious about an honest answer from the perspective of our interest as those who are planning on cryo for themselves.

A question for cryonics advocates. Would you also encourage people who can't obtain a cryonics contract to keep thorough diaries, on the grounds that such diaries would one day allow the creation of a person with memories and personalities modelled on those recorded in the diaries?

Vijay's point seems to me like a near/far distinction. Thinking in near mode, we don't want to die. In far mode, we don't really care.

I would answer it by pointing out that the prospect of death may seem far and remote now that it really is in the far future, but people tend to dislike the thought of their own death more the closer that they get to it. Young people who've seen old people in helpless conditions have said "kill me if I ever end up in that state", then preferred to go on living even when they've ended up in the state in question, and worse. You may think that dying isn't such a big deal, now... but if you end up old enough that the prospect of death is actually relevant, then you may very well find that you'd actually prefer to go on living, and regret not having made preparations for it earlier.

(This, of course, is exactly what the near/far hypothesis would predict.)

I have had one fundamental question with the motivation for cryonics. Why does one want to be open to the possibility of immortality in a theoretical sense like this? There is no "reason" why I want to live except that it is hardwired into me by evolution, the same way the sex drive is hardwired into me.

And my hardwiring doesn't predispose me to be very enthusiastic about being potentially alive in a theoretical sense that cryonics might offer. Suppose it were even possible to store perfect information about me w.r.t where all the fundamental particles in me are present. I would see no reason to pay money so that a future technology will resurrect me in that fashion using that information.

I guess the reason we dislike death is that it is usually painful or annoying in some way and doesn't happen in a wierd discontinuous fashion. Otherwise the post death state is probably no different than before we were born, and I doubt if any of us have a problem with the knowledge that there existed times in the past when we did not exist.

no need to go into trillions. (i think it works 1 in 2.7 trillions. as if that matters)no way this humans thing has a happy end. things are moving too fast now for society to learn/adapt. i put this at 30%.

also if we're forced to cram to the poles to survive a meek 4C increase in temp as it's expected, do you think humanity will carry the freezers of dead kooks with them? i put this at .1%

also by the time they freeze you, your aged brain will have lost most of the functions/memories anyway. unless you do it at 50 in which case you're nuts. and don't deserve to be preserved.

and even if it works, who wants to work/commute forever anyway?

>I consider the chances of revival to be less than one in a trillion

Zac, how did you arrive at that number?

On the one hand, you could say, "But the insurance company expects to make a profit and your utility function is convex in money; so if you wouldn't spend $28,000, you shouldn't spend $300/year." However, this only equates to the question of whether you would spend $28,000 to avoid certain death.

Ok, I like the future, and I think revival is possible, so I don't believe in any of the standard anti-cryo arguments. But cryonics seems quite expensive relative to other things I could do with my money. Like get more "life" by having to work less, hiring a trainer in order to be in better shape (and have less chance of death), that sort of thing.

So I don't do it for cost reasons. Am I wrong?

I can't imagine anything useful being achieved by reviving someone just to torture him. Presumably we wouldn't be useful slaves by the standards of this advanced civilization.

All in all, I don't see a lot of downside in the post-thawing scenario, although there probably are serious financial and social costs prior to preservation.

I've observed that many cost-benefit analyses of cryonics assume that the future can only get better. But I don't see any reason to take that as a given, and if you assume that the future might be worse instead of better, that significantly changes the analysis.

"The future" doesn't exist as a lump given all at once to revived cryonauts. If we survive to a time where we have realistic expectations of healthy superlongevity but the immediate conditions don't appeal to us, what keeps us from toughing it out, especially if we band together for mutual support, until either we or the conditions change so that things suit us better?
