Ouroboros on Cryonics
Chris Patil of Ouroboros is a cryonics skeptic: "I'm a cryonics skeptic of the 'extraordinary claims require extraordinary evidence' flavor. As I've said before, I suspect that long-term preservation of the potential for life by freezing or other means is physically possible, but at present I don't think we’re making any significant progress in that direction. Part of the problem is that there's very little serious initiative within the mainstream of academia or industry to build the many, many necessary precursor technologies. Another part is that the problem is really, really hard - harder than the comparatively simple but still unsolved problem of maintaining cellular viability within tissues at low temperatures." From reading what he's written, I think he's either out of the loop on the technology of vitrification, or not convinced that present day vitrification methods as used by Alcor are actually going to preserve fine structure in brain cells (i.e. preserve the data that is the mind). I disagree with him on that last point, if that is his view - the evidence clearly points to the viability of vitrification on that count.
