I am a cryoskeptic because I don't believe the pattern theory of identity, but in any case, it seems that this is a rather important issue for people who do, and who are seeking cryonic suspenstion. This thread (and Mike Darwin's blog) are full of detailed histories and analysis about numerous aspects of cryonics. But I don't see an analysis anywhere of how the organizations rate, when evaluated specifically from the perspective that atomic-scale mapping and reconstruction/simulation of the suspended brain will become possible, and that this is enough for personal survival. If we assume this to be true, and if we put aside considerations about the relative ability of cryonics organizations to keep their patients frozen - just focusing on the specific suspension procedures that they apply - how do they rate? Are any of them "not good enough", even by these assumptions? Or do they all get a pass?
