They also will not do anything until you have been on dry ice for 2 weeks after they have been contacted, so not being a member is more risky.
That seems prima facie to be really, really detrimental for the purposes of keeping the informational state unscrambled / recognizable (it may be sensible from a legal / PR POV, but I'm not much interested in that).
In a fun twist, it may well turn out that the "first" reconstituted bodies are worse off (lower-fidelity reconstruction), and you could argue that once mankind (shepharded by an automated sheepdog) reached a stage of thawing the dead, you're better off waiting for the trajectory to continue on, i.e. to stay frozen for a few centuries longer until perfect fidelity is achieved (on the flipside, society may be even less recognizable). One way to do that is to make sure the damage is severe, e.g. by botching the cryonic procedure somewhat, such as staying on dry ice for 2 weeks. Shmart (the 'h' is an artifact)!
o.O
that is a terrible idea. The damage could very easily be severe enough that you just killed yourself such that even a superintelligence couldn't figure out who you'd been.
In the past, the Cryonics Institute has had a policy that said that they would not accept anyone who is not a member. This has changed. The policy now is that someone who has full legal authority over your body can sign you up after you die. It costs $36,250 to be frozen if you are not signed up, which is more expensive. They also will not do anything until you have been on dry ice for 2 weeks after they have been contacted, so not being a member is more risky.
This is very important news for anyone who is currently cryocrastinating. It means that you can drastically increase your chances of survival without filling out any forms. All you have to do is tell a loved one you want to be frozen upon death, and that you would like them to take responsibility for making sure this happens. This takes literally 30 seconds. Do it now!
This news might also be a reason to not sign up right away, if you think something better (like radical life extension or uploading) will come along in your lifetime. We should discuss this in the comments.
Edit: The general consensus of this discussion is that this is a really bad reason not to sign up for cryonics.
