It has come to our attention that our recent presentation has caused some controversy on the CI members mailing list. As far as we can tell, a lot of the criticism is aimed at how other people (including Alcor Officials) have interpreted our presentation. In our presentation there is no comparison between Alcor and CI at all. As a matter of fact, we deliberately avoided framing the issue like this. Our presentation just summarized the practical implications of our research for cryonics. One of the most robust findings in our studies, and scientific papers of others researchers going back to the 1960s, is that cerebral ischemia produces perfusion impairment in the brain in a time- and temperature dependent manner. In cryonics such perfusion impairment translates itself into ice formation. The real difference is not between Alcor and CI but between people who do not receive rapid stabilization and cooling and those who do. In ourpresentation we outlined a number of things CI members can do to reduce warm and cold ischemia, including relocation and ensuring that there will be rapid cooling after pronouncement of legal death. We did not use the phrase “2/3 of CI members” in our slides but we did point out that the majority of CI members experience prolonged periods of warm and cold ischemia—this can be easily verified by checking the case reports on the CI website. Such ischemic delays produce perfusion impairment and ice formation. Most CI members can do something about the probability of this happening to them, so this can hardly be construed as an endorsement of Alcor. As a matter of fact, speaking for myself, I prefer a model where a cryonics organization leaves more flexibility to its members as to whether and how to make arrangements to prevent injury to the brain after pronouncement of legal death. We would never claim that the ischemia that many CI members experience is catastrophic because we do not know what future cell repair technologies will be capable of. Of course, this should not excuse people to limit postmortem damage as much as they can.
Having said all this, this does not mean that research cannot contribute to mitigating some of the effects of prolonged warm and cold ischemia. We made a number of recommendations during our presentation and hope to present a more comprehensive set of technical recommendations to improve CI procedures in the near future. We had constructive exchanges about this with Ben and Andy.
You could say that billions of dollars spent on cancer research is a huge waste of money because curing cancer has not been proven to work in small mammals. There is no proof that cancer can be cured. I am not being entirely sarcastic about this, but I would give a higher probability for success to most of the Strategies for Engineered Negligible Senescence to achieve rejuvenation. Knowledge of the forms of damage that result in aging is the first step toward repairing that damage. With cryonics the problem is similar: there is damage to be repaired, and it is not unreasonable to believe that in 50 or 100 years the molecular repair technology will be available. It would be foolish to believe that humans will never be able to live on Mars until you see humans living on Mars. The ability to extrapolate from present technology to future technology requires more sophistication than simplistic empiricism.
