Putting aside the specifics about Alcor for a moment, what about this would this make you want to drop out of Cryonics entirely? There are other options.

  1. Cryonics Institute is another reasonable organization.
  2. Oregon Cryonics has fairly cheap choices if that is your concern.
  3. You could try to advocate for better options and/or wait for others to emerge before “giving up”.
Comment by Synaptic on Conflict in Kriorus becomes hot today, updated, update 2 · 2021-09-08T00:04:24.917Z · LW · GW

This is from Wikipedia and doesn't really explain the full context. Cryonics in the 1960s/early 1970s was an absolute failure, but within the US, they learned hard lessons since then. Alcor and Cryonics Institute are both non-profits and seem like pretty stable organizations. If you disagree about that please let me know why. 

Comment by Synaptic on Cryonics signup guide #1: Overview · 2021-06-12T09:52:05.968Z · LW · GW

A relevant data point is that, as of a few years ago, I believe Mike Darwin wrote that he was still signed up with Alcor. As he pointed out, despite the problems with existing organizations, cryonics is the only game in town for avoiding death.

Sadly, Bederson’s evidence is mostly anecdotal and therefore not very trustworthy.

Comment by Synaptic on Anti-Aging: State of the Art · 2021-01-05T10:48:23.869Z · LW · GW

However, several of the parameters would be likely to be unaffected by increased funding: 

  • Cryonics is continuously legal
  • Cryonic revival is permitted

On the contrary, I very much expect that more funding would help with these factors. The success of cryonics is limited by sociopolitical factors, and the more people who have buy-in, the more likely people are to be protected when in long-term cryopreservation. 

The intention of my post was not to encourage reductions in funding into cryonics; rather, to increase awareness among LessWrongers readers about anti-aging. 

This is an admirable goal. =) 

Comment by Synaptic on Anti-Aging: State of the Art · 2021-01-04T12:01:58.601Z · LW · GW

I strongly support anti-aging research. I'm not clear on what your criticism is of cryonics. Perhaps I missed where you explained why you think that cryonics will not work? For example, where in the Drake equation does your probability differ from Steve Harris's or Mike Perry's? 

Also, you point out the large number of organizations and companies involved in aging research. Surely the fact that there are way fewer in cryonics means that it is has merit from an underfunding perspective? 

Comment by Synaptic on I'm looking for alternative funding strategies for cryonics. · 2019-06-30T15:11:21.910Z · LW · GW

You might get better responses at New Cryonet or r/cryonics. The cryonics community doesn't seem to be very active here.

It's a tricky question and depends a lot on your circumstances.

First, there are often cheaper options available. For example, CI is cheaper than Alcor. See https://www.reddit.com/r/cryonics/comments/8ymikj/oc_how_much_does_is_cost_to_preserve_a_brain/

If you have a terminal illness and don't have enough money for even cheaper options like CI, you can try to get in touch with the Venturists, who might be able to vouch for your situation and coordinate a fundraiser (they have done this in the past). Their website seems to be down but I think they are still active: https://web.archive.org/web/20170721065012/http://www.venturist.info/

Best of luck. I'm really sorry for your situation. It's a shame that cryonics is ridiculed and stigmatized and as a result the costs are much higher and this kind of situation is so hard to coordinate.

Comment by Synaptic on Why I think worse than death outcomes are not a good reason for most people to avoid cryonics · 2017-06-11T19:52:17.455Z · LW · GW

Upvoted -- I agree that the probability is higher if you do cryonics.

However, a lot of the framing of this discussion is that "if you choose cryonics, you are opening up Pandora's box because of the possibility of worse-than-death outcomes." This triggers all sort of catastrophic cognitions and causes people to have even more of an ugh field around cryonics. So I wanted to point out that worse than death outcomes are certainly still possible even if you don't do cryonics.

Comment by Synaptic on Can we decrease the risk of worse-than-death outcomes following brain preservation? · 2015-02-21T23:25:25.946Z · LW · GW

Well, this is certainly a reasonable response. But if there is a mechanism to decrease the probability that a worse-than-death outcome would occur so that people who had expressed these concerns are more likely to want to do brain preservation and more people could be a part of the future, that seems like an easy win. I don't think people are particularly fungible.

Comment by Synaptic on Can we decrease the risk of worse-than-death outcomes following brain preservation? · 2015-02-21T23:22:51.134Z · LW · GW

I think I did not explain my proposal clearly enough. What I'm claiming is if that you could see intermediate steps suggesting that a worst-type future is imminent, or merely crosses your probability threshold as "too likely", then you could enumerate those and request to be removed from biostasis then. Before those who are resuscitating you would have a chance to do so.

Comment by Synaptic on You Only Live Twice · 2015-01-18T18:38:08.671Z · LW · GW

it is very likely that my ticket out will be Alzheimer's or another neurodegenerative disease. In that case, cryopreservation will only make sense if I commit suicide at the very onset of the disease and am frozen right away which may not be possible. If I get Alzheimer's I may as well donate all my money to SIAI or Africa.

Consider two possibilities:

1) Alzheimers breaks long-distance communication more than it does actual information such as memories. Cf moments of lucidity. It's not clear how true this is, though.

2) It may in fact be possible to undergo controlled legal death at the onset of death in some number of years. See the Oregon laws, which are likely to start to be passed elsewhere. See also http://www.evidencebasedcryonics.org/2012/05/09/revisiting-donaldson/

Comment by Synaptic on You Only Live Twice · 2015-01-17T04:56:18.462Z · LW · GW

Can you describe the reasons are that make you think it is not likely enough to work? Totally understandable if you can't articulate such reasons, but I'm just curious about what the benchmarks are that you might find useful in informing your probability estimate.

That is to say, it's unlikely that actual reversible cryopreservation would be possible; if it were, the technique probably wouldn't be called cryonics anymore. So, other more intermediate steps that'd you'd find informative might be good to know about.

"Brain degradation after death" is the key point in this list that I'd be interested in learning about. I'm not sure if it's proper to ask this in a comment now or should I be studying diligently around the issue, but I think it's also an interesting subject so excuse me.

Yes, good intuition. This is what Mike Darwin considers the largest problem in cryonics: http://chronopause.com/index.php/2011/02/23/does-personal-identity-survive-cryopreservation/

Comment by Synaptic on More Cryonics Probability Estimates · 2012-12-18T21:29:20.501Z · LW · GW

simply long-term structural changes in the brain to seeing memories as the products of "continuous enzymatic activity"

Long-term structural maintenance requires continuous enzymatic activity. For example, the average AMPA receptor lasts only around one day: http://www.ncbi.nlm.nih.gov/pubmed/18320299. The actin cytoskeleton, made up of molecules which largely specify the structure of synapses, also requires continuous remodeling. If a structure is visibly the same after vitrification (not trivial), that means the molecules specifying it are likely to not have changed much.

Upvoted the post. Worthy thing to discuss.

A reply to kalla724 that you did not mention is here: http://lesswrong.com/lw/d4a/brief_response_to_kalla724_on_preserving_personal/

Kalla724 claims that it is not possible to upload a C. elegans with particular memories and/or behaviors. I think that this is a testable claim and should shed light on kalla724's views on preserving personal identity with vitrification. I also think it is likely wrong.

Comment by Synaptic on Brief response to kalla724 on preserving personal identity with vitrification · 2012-06-17T23:17:25.753Z · LW · GW

There is an experiment testing something similar to this in rats. They retain their ability to navigate a maze following hypothermia. Andjus, 1956:

The differences in retention of the maze habit among experimental and control groups were very small and in no instance were they statistically significant, although there was a consistent trend towards poorer retention following hypothermia. These small differences may be functions of the technique used to reduce deep body temperature rather than of the effects of hypothermia per se.

These results are based upon observations of the behaviour of non-hibernating, homoiothermic animals. With such animals, extreme hypothermia, such as that employed in the present study, results in complete arrest of heart beat, circulation, and respiration. It also suppresses electrical activity in the brain and in our animals cerebral activity may have been arrested for as long as 13 to z hours. Within the limits of our experimental procedure we have failed to find evidence that arrest of these vital metabolic processes as a result of hypothermia produces any very serious, permanent effects on the animal's behaviour once i t has been successfully reanimated. If, as previous writers have suggested, severe hypothermia can be used to “… stop all nerve impulses in the brain momentarily …” (Gerard, 1953), our results are difficult to explain if long-term memory is dependent upon the continuous activity of the brain.

Comment by Synaptic on Brief response to kalla724 on preserving personal identity with vitrification · 2012-06-17T21:07:10.227Z · LW · GW

I think it would teach us whether freezing and reviving with learning preserved was actually possible or not. This strikes me as important and useful information. That C.elegans has some inbuilt ability to survive freezing would confound it slightly, but I still think it's a necessary thing to at least look at.

I agree it would be useful. My wording was less charitable than it should have been. Still, the second test seems more definitive.

I really doubt the scientific exploitation of C.elegans is as hard as that would imply, compared to the numbers of mice and rats killed daily for science.

True, C. elegans experiments wouldn't be hard to do.

Has this experiment, or something like it, even been postulated anywhere in the past 20 years, or is it not as obvious to everyone else as it is to you and me?

There are lots of worm people and I don't know that much about the field. For all I know the experiment has already been done.

You should be a scientist!

That little? (I can believe it, though.)

As far as I know there are currently three labs in the world researching cryonics.

1) The de Wolf's and Ben Best, researching at the lab they made, Advanced Neural Sciences. Their budget is tiny, $20,000/yr (pdf). And this seems to be almost all private. But this is the best out there.

2) Joao Pedro de Magalhaes. His lab was just funded by a public fundraiser ($12,000) to do an RNA-sequencing experiment to learn about mechanisms of cryoprotectant toxicity.

3) Brian Wowk and Greg Fahy at 21CM. They invented M22 and have done most of the useful work over the past 10 years. And even their website says,

Although our research is of great interest to those who are interested in cryonics, 21st Century Medicine is not involved in cryonics.

So, compared to most other fields there is nobody researching this. Which annoys people like Mike Darwin and Ken Hayworth so much. This could work, but we don't know, and we as a society are hardly trying to find out.

Comment by Synaptic on Brief response to kalla724 on preserving personal identity with vitrification · 2012-06-17T20:12:14.393Z · LW · GW

the experiment to do is obvious

Two experiments:

a) Teach a bunch of C. elegans the tap-withdrawal reflex, freeze them, thaw them, and see if they still know it. This is what I'm assuming you were referring to. I actually don't think this is all that useful for testing the preservation abilities of cryonics. C. elegans have vastly different life cycles from humans and the ability to freeze them isn't that generalizable. See Casio's comment above: http://lesswrong.com/r/discussion/lw/d4a/brief_response_to_kalla724_on_preserving_personal/6u7e

b) Teach a bunch of C. elegans the tap-withdrawal reflex, freeze them, and do cryo-electron microscopy on them to determine the distribution and density of vesicles and receptors at the key synapses involved. Feed that data as parameters to a simulation and see whether the simulation reflects the tap-withdrawal learning experience of that particular C. elegans, as compared to controls. This will help shed light on whether personal identity is inferable from the kind of structural data that might be preserved by vitrification in human brains.

The experiment I prefer is the second. It will take time.

So why, in twenty years, has no cryonicist apparently done the experiment?

There is next to no funding for cryonics research. And massive regulations against doing animal-based experiments without government approval.

Comment by Synaptic on Brief response to kalla724 on preserving personal identity with vitrification · 2012-06-16T17:22:26.391Z · LW · GW

Post-translational modification of proteins is involved in some types of memory. Sustained post-translational modifications are likely to involve changes in gene expression. Otherwise, the system would not be very robust.

Changes in gene expression are likely to involve changes in the cell's epigenome.

Even if the post-translational modifications are gone after you replace water with cryoprotectant, the epigenome might be still stable. This would allow you to see what the changes in gene expression were. So, you might be able to tell what the memory was.

This is not a new idea. Ben Best:

Considering that the structure and function of Aplysia neurons are so similar to vertebrate neurons, it seems quite plausible that memory is stored by increasing synapses, increasing active zones and increasing transmitter vesicles at selected neurons in the brain — although we must await definitive proof. Assuming that memory is stored by this means, it seems unlikely that cryonics procedures could be perfected well-enough to preserve short-term memory, but avoiding structural damage to synapses and the active zones of synapses may be adequate to preserve long-term memory. It is probably even more important to preserve the state of the transcription regulator proteins in the neuron nucleus — such preservation may be adequate for reconstruction even if the synapses and active zones are lost. It may be even more difficult to reconstruct the state of the transcription regulator proteins from the number of synapses and active zones. The "redundancy" of information may be very valuable where there is partial destruction of both the transcription regulator proteins and the synapses.

You also say:

Is either meaningless or flawed, probably both

It could definitely be flawed. We don't know. That's why I used two conditionals in the sentence you quoted.

The whold post reminds me of the idea on LessWrong that one might as well just assume Omega will reconstruct you based on trace evidence in the physical world.

What part of

It's also important to stress that this only occurs under ideal conditions. Given the current practice of cryonics, cryoprotectant will not reach many or most areas of the brain. In these cases, there is a large amount of ice damage and the information is much more likely to be irretrievable.

did you not get?

I have little idea what it is trying to argue.

My main point is that kalla724 is too pessimistic about cryonics. We don't have a lot of answers to important questions and therefore can't say with so much confidence (p = 10^-22) either way.

Comment by Synaptic on Open Thread, June 16-30, 2012 · 2012-06-15T19:55:16.488Z · LW · GW

It's useful to distinguish between types of skepticism, something lsparrish has discussed: http://lesswrong.com/lw/cbe/two_kinds_of_cryonics/.

kalla724 assigns a probability estimate of p = 10^-22 to any kind of cryonics preserving personal identity. On the other hand, Darwin, Seung, and Hayworth are skeptical of current protocols, for good reasons. But they are also trying to test and improve the protocols (reducing ischemic time) and expect that alternatives might work.

From my perspective you are overweighting credentials. The reason you need to pay attention to neuroscientists is because they might have knowledge of the substrates of personal identity.

kalla724 has a phd in molecular biophysics. Arguably, molecular biophysics is itself an information science: http://en.wikipedia.org/wiki/Molecular_biophysics. Depending upon kalla724's research, kalla724 could have knowledge relevant to the substrates of personal identity, but the credential itself means little.

In my opinion, the more important credential is knowledge of cryobiology. There are skeptics, such as Kenneth Storey, http://www4.carleton.ca/jmc/catalyst/2004/sf/km/km-cryonics.html. There are also proponents, such as http://en.wikipedia.org/wiki/Greg_Fahy. See http://www.alcor.org/Library/html/coldwar.html.

ETA:

Sebastian Seung stated plainly in his most recent book that he fully expects to die. "I feel quite confident that you, dear reader, will die, and so will I." This seems implicitly extremely skeptical of current cryonics techniques, to say the least.

Semantics are tricky because "death" is poorly defined and people use it in different ways. See the post and comments here: http://www.geripal.org/2012/05/mostly-dead-vs-completely-dead.html.

As Seung notes in his book:

Irreversibility is not a timeless concept; it depends on currently available technology. What is irreversible today might become reversible in the future. For most of human history, a person was dead when respiration and heartbeat stopped. But now such changes are sometimes reversible. It is now possible to restore breathing, restart the heartbeat, or even transplant a healthy heart to replace a defective one.

The critique reduces to a claim that personal identity is stored non-redundantly at the level of protein post-translational modifications. If there was actually good evidence that this is how memory/personality is stored, I expect it would be better known. Plus if this is the case how has LTP been shown to be sustained following vitrification and re-warming? I await kalla724's full critique.

This has been discussed here. Enoosti:

Yes, the paper clip reference wasn't the only point I was trying to make; it was just a (failed) cherry on top. I mainly took issue with being revived in the common dystopian vision: constant states of warfare, violence, and so on. It simply isn't possible, given that you need to keep refilling dewars with LN2 and so much more; in other words, the chain of care would be disrupted, and you would be dead long before they found a way to resuscitate you. And that leaves basically only a sudden "I Have No Mouth" scenario; i.e. one day it's sunny, Alcor is fondly taking care of your dewar, and then BAM! you've been resuscitated by that A.I. I guess I just find it unlikely that such an A.I. will say: "I will find Yvain, resuscitate him, and torture him." It just seems like a waste of energy.

This has also been discussed here. humpolec:

What you're describing is an evil AI, not just an unFriendly one - unFriendly AI doesn't care about your values. Wouldn't an evil AI be even harder to achieve than a Friendly one?

It has also been discussed here. Michael Vassar:

It would take quite a black swan tech to undo all the good from tech up to this point. UFAI probably wouldn't pass the test, since without tech humans would go extinct with a smaller total population of lives lived anyway. Hell worlds seem unlikely. 1984 or the Brave New World (roughly) are a bit more likely, but is it worse than extinction? I don't generally feel that way, though I'm not sure.

Comment by Synaptic on Mike Darwin on the Less Wrong intelligentsia · 2012-02-28T05:02:16.341Z · LW · GW

Marginal costs could go down with scale, but there is a lot of evidence that it is difficult to scale up, and costs would need to fall a lot.

Would you mind going into details?

Plastination is a route that has been discussed but has had in my understanding zero research devoted to actually understanding whether it would work in humans for preserving personal identity. Ken Hayworth says that it could cost just a few thousand dollars.

Right now it may seem like there is no cheap route for effective brain preservation, but it is also clear that we as a species have not tried very hard to find out. Do you weigh that uncertainty in your calculations?

People saved from malaria can actively take care of themselves and preserve their own lives

One counter to this, which I do not necessarily endorse, is that people saved from malaria may also contribute to the world in negative ways, whereas preserved people are only likely to be revived if future society has good reason to believe that they will be a net positive.

ETA: Then again, I suppose there could also be strife and violence about the status of the preserved individuals, which actually might be worse in EV.

Comment by Synaptic on Mike Darwin on the Less Wrong intelligentsia · 2012-02-28T04:05:38.293Z · LW · GW

Thank you for the clarification of your stance. The best counterargument seems to be that brain preservation has the potential to save many more lives than are lost due to malaria, if properly implemented, and yet receives very little if no funding. For example, malaria research received 1.5 billion in funding in 2007, whereas one of the only studies explicitly designed as relevant to cryonics is still struggling to reach its modest goal of $3000 as I write this.

they have a nontrivial chance of living to see a positive singularity/radical life extension to get there

How you do define and estimate this probability?

plus GiveWell builds the effective altruism community and its capabilities

True. But donations to cryonics organizations build the effective brain preservation community and its capabilities, and once again we are back to the question of which has the higher marginal expected utility.

Instead of stretching to argue that pushing cryonics is really at the frontier, better to admit you want to do it for non-existential risk reasons

Fair enough, I'll defer to your expertise on existential risk.

Comment by Synaptic on Mike Darwin on the Less Wrong intelligentsia · 2012-02-28T03:30:50.560Z · LW · GW

This was the quote I was referring to:

So, I often have a nagging worry that what I’m working on only seems like it’s reducing existential risk after the best analysis I can do right now, but actually it’s increasing existential risk. That’s not a pleasant feeling, but it’s the kind of uncertainty you have to live with when working on these kinds of problems. All you can do is try really hard, and then try harder.

I was referencing how it is difficult to effectively lead an organization that is so focused on the distant future and which must make so many difficult decisions.

I should have been clearer.

Comment by Synaptic on Mike Darwin on Steve Jobs's hypocritical stance towards death · 2011-10-08T14:56:33.031Z · LW · GW

And you are talking as if Jobs's moral stances do not hold especially more weight than other's do, as if his opinions were just the opinions of another guy, not something special. That is, when Steve Jobs says "don't mind death, it's ultimately a good thing," people listen.

If he had said "when people develop dementia, they are no longer able to contribute to society and thus we should accept their passing," I would still disagree, but at least his (near mode) actions would not be inconsistent with his (far mode) words.

But no, he makes no attempt to distinguish whether an individual can still contribute to society in his unabashed glorification of death, and therefore we should (likewise) not forgive his hypocrisy because he was still able to contribute.

One funny thing is that "cryogenics" and the singularity are so often lumped together, even though interest in them is for many people inversely correlated--if you believe in a near singularity (and are relatively young), you don't need cryonics for personal survival, and if you don't believe in a near singularity, you do need cryonics.

The patients have heart rate monitors with GPS signalers that signal the cryonics company as soon as the patient flatlines. This is just obviously the way things should be and it is regrettable that the market is not yet broad enough for 'obvious' to have been translated into common practice.

See http://www.benbest.com/cryonics/alarms.html:

"For over fifteen years I have been hearing that the kinds of systems cryonicists would want for vital signs alarm systems will be commercially available within a year or two. In that sense, December 2010 is not that much different from 1995, except that the claims are getting louder and more convincing. I should be getting excited, except that over a decade of feeling like the village idiot chasing a wallet on a string has made me very cynical....

Cryonicist Nick Pavlica seemed to be making some progress with his bed alarm, but after extensive testing by me, I still must say that it gives false alarms or does not alarm when it should. At the moment, the best I can say for the product is that it appears to provide a good panic-button system for dialing to a pre-programmed list of phone numbers."

Comment by Synaptic on Cryonic suspension where? · 2011-09-28T02:40:55.937Z · LW · GW

The relevant question seems to be Alcor vs CI. Form what I can tell, ACS is expensive and does its storage with CI anyway.

Alcor costs (http://www.alcor.org/BecomeMember/scheduleA.html):

$200,000.00 Whole Body Cryopreservation ($110,000 to the Patient Care Trust, $60,000 for cryopreservation, $30,000.00 to the Comprehensive Member Standby (CMS) Fund),

OR $80,000.00 Neurocryopreservation ($25,000 to the Patient Care Trust, $30,000 for cryopreservation, $25,000.00 to the CMS Fund).

CI + SA costs (http://www.cryonics.org/comparisons.html, and http://www.cryonics.org/SA/SA_CI_Attachment_2.html):

$28,000 CI whole body preservation, with personal shipping,

OR $28,000 + $52,500 cost for SA ($7,500 deployment, $30,000 transport, $15,000 air transport) = $80,500.

Note that this is a minimum for the deployment costs of SA. If the personnel are deployed for longer than 2 days or more than once, the costs rise.

From what I can tell, CI does not mention putting money aside for a patient trust.

Summary:

If you live in Michigan, prefer whole body preservation, and/or your associates are willing and able to competently deal with your transport, then CI would be a relatively better deal.

If you don't mind neurocryopreservation, prefer SA for skilled transport, and/or are more concerned about the long-term stability of the organization (due to the patient trust fund), then Alcor would be a relatively better deal.

Note that the annual dues of Alcor are much higher, $800 (if you get CMS, which is pretty much essential) to $120. This adds up, and if you live 40 more years, is equal to $32,000 (and more once you inflation-adjust).

Given this annual fee structure, it might make relatively more sense to sign up with CI when you are younger and switch to Alcor when you are older.

My main advice is to start on life insurance first. I also recommend Rudi Hoffman.

Yes, I agree both of these matter. I wonder which one is more important?

First, I think this post was a good idea, and thanks for taking the time to write it and for putting yourself out there.

Consider reading about http://en.wikipedia.org/wiki/Cognitive_behavioral_therapy, and see whether that was the strategy which your therapist used. If not you might want to broach the topic with your parents and see whether they'll find you a therapist who will use CBT. Worth a shot, although it's [not necessarily efficacious in depression].

On the other hand CBT does not work for all people. I'd really suggest for you to have and/or "buy" some fun. Selfishness in the short run is often for the good of everyone in the long run.

It is also illegal in France. See http://www.depressedmetabolism.com/2010/10/11/october-2010-cryonics-symposium-in-germany/ : "In the late 1960s the Cryonics Society of France was the largest cryonics organization outside of the United States. Roland was the President and Anatole Dolinoff was Vice-President. Roland showed me a list of officers and directors of the organization, pointing-out who had been fighting with whom, and the fact that virtually all were dead without having been cryopreserved. Dolinoff believed that cryonics was illegal in France because of a decree issued by the French Minister of Health in 1968."

Also see http://www.cryonet.org/cgi-bin/dsp.cgi?msg=7353

Possibly this could be due to fear of the spread of US culture into france. See, for instance, how the French also recently banned the use of the words "facebook" and "twitter" on tv: http://www.huffingtonpost.com/2011/06/03/french-ban-twitter-facebook_n_871153.html

OK, I update my "surprise" based on this info that you donate so much to charity. Good stuff.

I was using that as an example of how 1) donations to well-meaning and efficacious current charities can have unintended negative consequences in the long run (i.e., make people dependent), and 2) investments in scientific research (including the societal infrastructure to support it) tend to pay off great dividends in the long run.

I agree that $300, with no concomitant time investment, would probably not be enough.

I guess I'm just surprised that a (smart) person could read all of this information about a potentially hugely transformative technology, assign such a low probability (20%) to the likelihood that "not all of what makes you you is encoded in the physical state of the brain," and still just generally not care much and prefer to go play music instead. I just don't get it. Maybe I'm weird.

Similarly, does it take more than an additional $300/year to double my chances of revival?

I don't know, what do you think? It seems to me that if you can figure out some way to help the brain preservation foundation (http://www.brainpreservation.org/) develop a non-cryogenic (i.e., room temp) method of preservation, it could much more than double your chances.

Unfortunately for cryonics, it has tough competition as a charity. I don't think it comes anywhere close to givewell's top charity.

Looking back on it, which activity has had more benefit over its lifespan, the development of antibiotics in the 1930's, or the development and enactment of the US welfare state in the 1930s? Which one cost more money?

Comment by Synaptic on Convincing my dad to sign up for Alcor: Advice? · 2011-09-26T14:45:28.564Z · LW · GW

I think it is going to have to be a slow process.

First, you should try to convince him on the intellectual level that cryonics is feasible. If he is willing to read and likes science, this might be a good post to send him a link of: http://chronopause.com/index.php/2011/02/23/does-personal-identity-survive-cryopreservation/. I also might send him a link to the wikipedia page: http://en.wikipedia.org/wiki/Cryonics, which is pretty balanced. Frame it is an academic exercise. Who knows, maybe he can poke some holes in it? (And if he does, please report them back here.)

Second, only once (and if) he becomes convinced of its academic merits would I try to convince him to personally sign up. At that point I would pull out the "I'm your son and don't want to see your identity erased" card. Then use arguments similar to http://lesswrong.com/lw/wq/you_only_live_twice/.

But do note that the vast majority of people who are interested in cryonics self-select for it, and based on prior odds, you are unlikely to be successful in your endeavor. Sorry.

I upvoted because this is a good effort to make your probabilities explicit.

One meta point: A lot of this seems a bit too nihilistic. Cryonics is small, very small. If you, Jeff Kaufman, decide (and actually go through with the process) of signing up, that act non-trivially decreases the probability that cryonics will be outlawed. If you decide to contribute even in some small way to the (non-profit) org, that act decreases the probability that the org will fail, scaled (enormously) by how actively you engage. If you move closer to the org you sign up with, that increases the probability of a good cryopres. If you don't engage in risky behaviors, that decreases the prob of an acute event which would disallow a cryopres. If you exercise, that decreases the prob of developing AD. And etc.

You seem to be approaching cryonics as pure consumption, when you stand to gain much more (and do much more good, see http://www.overcomingbias.com/2010/07/cryonics-as-charity.html) if you consider it more of an active pursuit.

Perhaps it is easier, mentally, to ignore this factor (which others, including Robin Hanson, seem to have done), but it doesn't seem prudent.
