Knowing full well all the damage inflicted by today's freezing techniques, and being ignorant of the prospects for repairing it, most cryobiologists believe cryonics cannot work. They view it as an illegitimate pursuit that attracts unwarranted media attention, and that tarnishes the image of their own profession. The resulting hostility toward cryonics is often so great that even cryobiologists sympathetic to cryonics cannot openly state their views without fear of ostracism. The cryobiologist Arthur Rowe is responsible for promoting this misrepresentation. The analogy is not valid.
Some vertebrates can survive freezing, but no vertebrates can survive grinding.
Cryonics patients are frozen long before most of their cells die or become structurally disorganized. I don't know if they could survive grinding, and I don't know if each piece occupies the same location after dicing as before. Dora Kent is the mother of Saul Kent, a longtime supporter of cryonics and leader of the Life Extension Foundation. Although Dora was clinically dead at that time, she was not legally dead due to an administrative oversight. The coroner autopsied the non-suspended portion of Dora's remains.
