Cryonics

I'm considering signing up with the Cryonics Institute. Are you signed up? I'd be interested to hear your reasons why or why not. It does of course sound crazy, but when you press past that initial reaction to find out why it's crazy, I haven't heard a really satisfactory argument yet, and I'm interested to hear what people think. There are many reasons it might not work, but are there reasons to think it's really unlikely to work? How likely does recovery need to be for it to be worth it?

Anti-cryonics links

I may not reply to everything in that 159-comment thread but thanks to everyone who participated. I hope people don't mind if I carry on asking for your help in thinking about this. I might post articles on specific areas people raised, but first I thought to ask this: my Google-fu may be failing me. I'd appreciate any links anyone can find to good articles arguing against signing up for cryonics, or pointing out flaws in arguments made for cryosuspension. I don't mean South Park, thanks :-) I'm looking for something that really intends to be persuasive.

thanks again!

Update: here's some I've found

• Ebonmuse, On Cryonics
• Ebonmuse, Who Wants to Live Forever?
• Why we'll never be downloaded
• Why Minds Are Not Like Computers - actually there's quite a lot of scholarly writing arguing that the idea of simulating a brain on a computer is not merely impractical but impossible in principle.
• Michael Shermer on cryonics
• Skeptic's Dictionary on cryonics
• Cryonics–A futile desire for everlasting life
• Quackwatch - Is Cryonics Feasable?
• Ben Best - Debates about Cryonics with Skeptics (Best is President/CEO of the Cryonics Institute, but this is a snapshot of a debate on the James Randi forums, with a link to the original forum debate)
• Frozen Stiffs, Ruth Holland, BMJ 1981

If you find any of these articles at all convincing, let me know and I'll point out the problems with them. Update: while I am definitely interested in continuing to read your arguments, I'm really really keen to know about anyone anywhere on the Internet who seems well-informed on the subject and writes arguing against it. Such people seem to be strikingly few and far between, especially on the specific question of the plausibility of recovery. There's a hypothesis here on why that might be, but I'm not sure it's enough to wholly account for it.
