"It just so happens that your friend here is only mostly dead. There's a big difference between mostly dead and all dead."
-- The Princess Bride
My co-blogger Robin and I may disagree on how fast an AI can improve itself, but we agree on an issue that seems much simpler to us than that: At the point where the current legal and medical system gives up on a patient, they aren't really dead.
Robin has already said much of what needs saying, but a few more points:
Ben Best's Cryonics FAQ, Alcor's FAQ, Alcor FAQ for scientists, Scientists' Open Letter on Cryonics
I know more people who are planning to sign up for cryonics Real Soon Now than people who have actually signed up. I expect that more people have died while cryocrastinating than have actually been cryopreserved. If you've already decided this is a good idea, but you "haven't gotten around to it", sign up for cryonics NOW. I mean RIGHT NOW. Go to the website of Alcor or the Cryonics Institute and follow the instructions.
Cryonics is usually funded through life insurance. The following conversation from an Overcoming Bias meetup is worth quoting:
Him: I've been thinking about signing up for cryonics when I've got enough money.
Me: Um... it doesn't take all that much money.
Him: It doesn't?
Me: Alcor is the high-priced high-quality organization, which is something like $500-$1000 in annual fees for the organization, I'm not sure how much. I'm young, so I'm signed up with the Cryonics Institute, which is $120/year for the membership. I pay $180/year for more insurance than I need - it'd be enough for Alcor too.
Him: That's ridiculous.
Me: Yes.
Him: No, really, that's ridiculous. If that's true then my decision isn't just determined, it's overdetermined.
Me: Yes. And there's around a thousand people worldwide [actually 1400] who are signed up for cryonics. Figure that at most a quarter of those did it for systematically rational reasons. That's a high upper bound on the number of people on Earth who can reliably reach the right conclusion on massively overdetermined issues.
Cryonics is not marketed well - or at all, really. There's no salespeople who get commissions. There is no one to hold your hand through signing up, so you're going to have to get the papers signed and notarized yourself. The closest thing out there might be Rudi Hoffman, who sells life insurance with cryonics-friendly insurance providers (I went through him).
If you want to securely erase a hard drive, it's not as easy as writing it over with zeroes. Sure, an "erased" hard drive like this won't boot up your computer if you just plug it in again. But if the drive falls into the hands of a specialist with a scanning tunneling microscope, they can tell the difference between "this was a 0, overwritten by a 0" and "this was a 1, overwritten by a 0".
There are programs advertised to "securely erase" hard drives using many overwrites of 0s, 1s, and random data. But if you want to keep the secret on your hard drive secure against all possible future technologies that might ever be developed, then cover it with thermite and set it on fire. It's the only way to be sure.
Pumping someone full of cryoprotectant and gradually lowering their temperature until they can be stored in liquid nitrogen is not a secure way to erase a person.

You don't have to buy what's usually called the "patternist" philosophy of identity, to sign up for cryonics. After reading all the information off the brain, you could put the "same atoms" back into their old places.
"Same atoms" is in scare quotes because our current physics prohibits particles from possessing individual identities. It's a much stronger statement than "we can't tell the particles apart wi...
