Dr. Wowk has stated that he needs cryonics to work, and so it provides me no information that he thinks cryonics works.
I don’t recall making any context-less statements that cryonics works. Obviously I think that cryonics is worth doing, but that’s not same as thinking it “works.”
I explicitly stated that the damage done by the best cryopreservation technology is severe by contemporary standards. It’s not compatible with revival by any near-term technology, no matter who does it. Nobody should be under any illusions that human cryopreservation by available technology is easily reversible.
The goal of cryonics is to prevent “information theoretic death,” or erasure of the neurological basis of human identity. Any criticism of cryonics procedures, and the extent to which procedures impact the prognosis of cryonics patients, must be with reference to that. That has been absent in any of the recent criticisms of cryonics related to qualifications of personnel. Recent criticisms of cryonics cases have been with reference to what would have happened to living medical patients had the same case problems occurred (i.e. they might have died). The criticisms have not been with reference to the biological impact on someone who’s already suffered a “fatal” period of cardiac arrest before the hospital even let cryonics procedures begin, and who is going to be perfused with cryoprotectants for hours, dehydrated, and then cooled to a temperature that results in thermal stress fractures through all major organs of the body, likely including the brain. In such circumstances, ultimately getting cryoprotectants into tissue is enormously more important than how long cannulation for field blood washout takes, within reason.
Regarding what Ms. Maxim believes about cryonics working, it was Ms. Maxim who took exception to me saying that she believed cryonics won’t work. She said:
I have never said I “don’t believe anybody’s survival actually depends on cryonics because it won’t work.”
I have CLEARLY stated I believe someone preserved in a fairly pristine state might be revived.
There are two possible interpretations of this. Either she believes that cryonics today done by the right people could result in a sufficiently pristine state, in which case she believes that cryonics today could work. Or she believes that the cryoprotectant toxicity, long cold ischemic times, and thermal stress fractures that are unavoidable with today’s technology are not sufficiently pristine to permit revival. In that case, the entire debate of qualifications of personnel and procedural details are academic to whether cryonics today does anybody any good because the technology is intrinsically not good enough to work.
