Calling it a "scam" implies that, not only is cryonics hopeless, but that the cryonicists agree it is hopeless and are just lying to people for money. Do you have any evidence of that at all?
Cult leader, ponzi schemer or other conman believing his or her own bullshit does't make a difference. Victims are lead to believe something with no basis in science, reason, logic or reality for the purpose of personal or financial gain.
Being a scam doesn't require the buy in or belief of the scammer.
Plenty has been written on Alcor[0] in particular[1], there is an entire book[2] written by a former employee. The entire industry is dangerous, weird[3], and preys on the vulnerable.
Some neuroscientists and cryobiologists think that cryonics deserves a second look as a way to try to turn death from a permanent off-state into a temporary and reversible off-state by approaching the problem as a challenge in applied neuroscience. They have set up the Brain Preservation Foundation to raise money for incentive prizes to encourage scientists to push hard on the envelope of current and reachable brain preservation techniques:
Two prominent figures in the skeptic community, Michael Shermer and Susan Blackmore, have lent their names to the Foundation as advisers, so they apparently consider the idea scientifically defensible:
GP asked for evidence, not for proof. Your refutation is a generic argument you could use on anything. I can only assume you understand this, (judging from your generally high-quality comments on this site). So I'm curious as to your reasoning for such a poor response. Is it just that you disagree there's useful evidence for cryonics and don't want to write more in-depth comments?
How much more in-depth can it get, I think I've written enough in this thread already and it seems to me as though the belief in the might of science outstrips the ability to reason. Science gave us guns and computers, therefore it will give us resurrection.
And then to ask for evidence is adding to the pile, the only admissible evidence here would be proof that it is indeed possible. And I don't see any such evidence, only very small bits and pieces which could possibly one day be expanded to a whole given unfathomable advances in technology.
The branches of science required to pull this off do not even exist yet.
Remember that old saw about advanced enough technology being indistinguishable from magic? That's the territory we're in here.
Technology is nuts-and-bolts stuff based on understanding, not modern variations on Pascal's wager.
Useful evidence for cryonics -> anything that can be used to market cryonics. Evidence against cryonics: nobody has ever returned from the dead. I realize that facing death is one of the hardest issues to come to terms with for the living but I'm a little but surprised how gullible the techies are when it comes to selling them a bill of goods like this.
I guess at some level everybody wants to live forever and companies like this handily tap in to that (as did every religion with a commercial aspect since millenia).
No, contradicting evidence would be quite admissible. For instance, showing that some major part of the structure of the brain decays immediately into noise would kill the idea of revival. As I understand, there's a bit of uncertainty, but generally, so far, it seems like it is in theory possible.
>not modern variations on Pascal's wager.
Pascal's wager is bad because it takes the current universe, then lets you pick from only 2 choices, and the god choice isn't free (as belief in something you know to be wrong is detrimental). If a superintelligence offered the wager with the condition that every other religion/afterlife was wrong, and the only two possibilities were god or no god, and that there was no cost (just have to say "I believe"), then Pascal's wager wouldn't be a joke.
I agree though that of course this is ripe for commercial exploitation. Just like an insurance fund that promised to try to get involved/fund every AI research initiative, in exchange for somehow giving you preferential treatment in case of a not-so-friendly singularity.
