X-Message-Number: 30 From: Kevin Q. Brown Subject: there must be a catch Date: 25 Oct 1988 If something sounds too good to be true, it probably is. Yet, cryonics offers people a chance for an extremely long and productive life. What's the catch? I have some speculations similar in flavor to one of Heinlein's aphorisms (which I can only paraphrase here since I do not recall the source): Save a thousand dollars at 10% interest for 200 years and it will become 100 zillion dollars, by which time it will be worthless. Cryonics may indeed work as planned, but not produce quite what cryonicists expect. Cryonicists share a vision of a future that: (1) has the nanotechnology and, in particular, cell repair machines necessary for reviving them from cryonic suspension, and (2) is worth coming back to (since otherwise they would not be preserved long enough to be revived). The expectation seems generally to be that when a person is revived, he or she will be healthy, young (if desired), and able to participate in a future world full of marvelous hi-tech toys. I won't argue that, but I suspect there also will be some "gotchas", even if the future world is quite benevolent. The first "gotcha" is that when people are finally revived from cryonic suspension, humans (as we know them today) will be obsolete. Not necessarily extinct, but no longer major players in the events of civilization; they will be anachronisms. This is because any technology that can build nanomachines to reassemble and repair 20th Century frozen sick people will be able to easily and remarkably enhance humans far beyond what we see today. Why would future people elect to be "brain damaged" when they could have libraries of information, high-bandwidth telecommunications, and the brainpower to effectively use it all easily built-in? Of course, newly revived people could presumably become similarly enhanced, too, and become "bigger" and more complex than they had the capacity to imagine before. This is not a bad "gotcha", but if one expected to wake up and find the world populated with the kinds of people with which one is familiar, the change is likely to be a shock. Supposedly "futuristic" stories such as those in Star Trek, which feature cowboys of the future romping through the galaxy, are both entertaining and misleading. They assume a future that will be much like the present, only bigger and faster. I do not believe it will be that simple. The second "gotcha" is that cryonicists do not like getting killed, yet a dominant personality of the future may be one that takes great physical risks and gets killed often. Why would this happen? When matter can be easily manipulated (by general-purpose nanotechnology) into almost any physically possible form, INFORMATION becomes the major commodity. When our most valued possession is information and we can decompose, transmit, and reassemble ourselves as information, our sense of self will become our information and bodies will be throwaways. Instead of a future society of potential immortals who always desperately try to avoid deadly accidents, we may see quite the opposite; if your backups are in order go take any physical risk you like! Furthermore, murder may become even more popular than it is today if everyone sees it as just a harmless practical joke. People newly revived from the 20th Century would doubtless say: "But that's not what I bargained for!". In what other ways may cryonic suspension work completely as planned, yet the future still come out "wrong"? Happy Halloween! - Kevin Q. Brown ...{att|clyde|cuae2}!ho4cad!kqb Q: How many cryonicists does it take to change a lightbulb? A: Four. One to ensure that the lightbulb is declared legally dead, one to perfuse it with cryoprotectants, one to slowly cool it to liquid nitrogen temperature, and one to wait a hundred years for technology to advance sufficiently to revive it.
