From Existence is Wonderful: "If you can manage to scrape away enough of the subcultural detritus and personality artifacts that have glommed onto cryonics over the years, what you're left with is: (a) an experiment in tissue preservation, (b) the idea that future technology may someday be able to repair injury and illness not addressable by today's medicine, and (c) a view of death as a process rather than a discrete event. None of these things seem to me particularly irrational or farfetched in and of themselves. Of course in reality you can't actually ignore the cultural connotations and fringe entanglements of something like cryonics. These things must be acknowledged and addressed if one wants to actually have a clear view of the subject, and that's part of what I am trying to do here. E.g., I think the notion of cryonics has been harmed by assertions that it's a means to (even potentially) 'buy immortality'. Immortality, after all, is incoherent - nobody knows how long they or anyone else is going to live, and it might end up being a pretty long time, but it sure as heck isn't going to be forever, any more than having a job gives you a shot at making Infinity Zillion Dollars."
