X-Message-Number: 7398 From: Date: Wed, 1 Jan 1997 15:03:49 -0500 Subject: Vitrification; Reality 1. WHY WAIT FOR VITRIFICATION? According to relatively recent published and unpublished word from Greg Fahy--if I understand it correctly--rabbit kidneys (and perhaps other specimens) can already be preserved, using his methods, by vitrification, and stored at liquid nitrogen temperature without significant damage. The main problem remaining is the RF rapid thawing required, which has also already been solved in theory but not yet in practice. >From the standpoint of near-future patients, why not use these vitrification methods (if applicable to brains)? The thawing problem (large licensed RF transmitters etc.) can be solved at leisure. We would really then HAVE brain cryopreservation that is reversible to a near-certainty. >From the standpoint of public relations, of course there would be very limited favorable reaction to e.m. photos showing no discernible damage to the vitrified brains. Until we get walking-around revived patients (mammals at least), only a few people will take the prospect seriously. But these numbers could still be substantial on our scale of business. Perhaps even more important, there might be a tremendous boost to morale in the ranks. By the time of the Alcor technology festival (Feb. 1-2) I hope to have some updated facts and figures to kick around. 2. REALITY is the heading of Charles Platt's Cryonet # 7390, partly suggesting that I am too confident about revival chances, and giving his own estimate (for current patients, presumably) of only one in 10,000. And indeed that is always what it is all about: who has the best grip on reality? I do indeed claim that the probability of revival--looking only at the SCIENTIFIC problems, not those of economics, sociology etc.--is closer to unity than to zero. Very few people have troubled to read the booklet I wrote about probability theory and cryonics, and probably few of those both understood it and gave it serious thought. But it is NOT true that "...it's all a matter of opinion;..." as Charles says. Not all opinions are created equal. For example, my opinion about certain aspects of the foundations of probability theory is superior to that of Richard von Mises, the great mathematician and one of the founders of the frequency theory of probability--even though he was much smarter than I am. Truth is not a respecter of persons or of reputations. I have PROVEN he was wrong about certain basic ideas, and offered better ones. This ties in with some recent exchanges on Cryonet about how broadly or how narrowly one should construe the scientific method or attitude. I assert that the scientific method is appropriate and applicable to ALL areas of life and thought. This is an understanding on which your life may depend. Centuries ago, or even millennia ago, any observer could have said that flying machines are possible, since many animals do in fact fly, and there was no reason to believe that those animals exhausted the possible types of flying machines. Of course, the narrow-constructionists of those eras could say, and did say, that such speculation was idle, since no engineer was close to an operational plan for a flying machine, and no known technology could duplicate the wings of a bird or a bee. So who had the better argument--those who looked at life in the large, at the sweep of experience; or those who wanted proof rather than evidence? No doubt I will continue to be accused of complacency or over-optimism, but I deny the charge. I could always be wrong, but I look at evidence, not druthers.
