There were some fantastic links here. Thankyou!

Does anyone here know what the break-down is among cryonics advocates between believing that A) in the future cryopreserved patients will be physically rejuvinated in their bodies and B) in the future cryopreserved patients will be brain-scanned and uploaded?

I think there is a reasonable probability of effective cryopreservation and rejuvination of a mammal (at least a mouse) in the next 25 years, but I think our ability to 'rejuvinate' will be largely dependent on the specific cryoincs technologies developed at that time, and that it is very unlikely cryonics methods developed before that time will be acceptable for rejuvination. Realize that once an effective cryopreservation method has been developed, socially there will be much more interest in perfecting it than there will be in going back to the old technology used to freeze past generations and figuring out how we can get that to work for their sake.
