In looking over the comments here, there are a few missed points that I believe heavily shift the balance in favor of having cryonics arrangements. The first is that the need for “cryonics,” in the generic sense, is never likely to go away. While it is true that we can currently envision technologies to repair all of the pathological processes we currently understand, that does NOT mean that we understand all of the things that both can, and will go wrong with us in the future.
Let’s assume that aging is conquered tomorrow. Within some definite (but unknown) period of time you are going to fill up your hard drive—or your “soft drive,” if you prefer. Humans were not designed to store thousands of years of memories and experiences. And we may be doing just that, if the people with Superior Autobiographical Memory are any indication. So unless you are happy with eventually losing most, or all of your current memories, something will have to change…
A likely consequence of this limitation is that we are going to have to reconfigure our brains. I use this very conservative example, because it speaks to the NECESSITY of doing this. Probably most of the people on LW envision, and even desire, vastly more daring reworks of their identity-encoding hardware and software. That will inevitably carry associated risk. It is very easy (at least for me) to envision major and very complicated screw-ups in cognitive re-engineering that cannot be easily or rapidly sorted out. In fact, this sort of thing happens today on a small, but nevertheless sometimes lethal, and not infrequently very damaging way, when people become psychologically confused, or “existentially damaged.” A good example is when seemingly normal people get taken over by ideas, or become ensnared in cults. Is “deprogramming” a treatment, or coercion? Malware, either deliberately designed or accidentally created, which badly damages programs and data are yet another example. So, leaving hardware out of consideration, it seems likely that people will still get very nasty “software” diseases that do a lot of damage in a short period of time, and that require that the “system” (person) be shut down until a solution can be found. Nanotechnology will not solve this problem because the problem is a meta-problem that is intrinsic to complex systems interacting in an open universe.
I also think it will also be a long time, if ever, before damage to “hardware” substrates becomes 100% repairable 100% of the time in REAL TIME. As long as it is possible to envision pathologies that render the individual into a degraded and nonfunctional state, which current technology cannot reverse, then you will need cryonics, regardless of what it is subsequently called or what preservation technology is used.
My next point is that there are a couple of implicit assumptions in the foregoing arguments which are demonstrably not true. The first is that cryonics is a discrete, consumable product, like a bag of crisps, a candy bar, or even a computer or a radio. Or that it is like an automobile maintenance contract, or an insurance policy that pays off when you need it.
It isn’t.
All of those products and services can be assigned, with a high degree of precision, a probability as to how they will perform and what your likelihood is of being satisfied with them. They are fully developed products. And mostly, all you need to know about them is present, free for the asking in your culture in the form of “common knowledge,” information from friends and family, and, of course, in advertising. You pay your money and that’s it. Nobody needs to explain to you, or to or anyone else what a TV or broom are for, how to use them, and what might go wrong with them over time.
This is no way describes cryonics.
So, the first benefit you get by signing up is that you now have a proprietary interest in learning what it is that you just bought; and you will soon become aware that you need to KEEP LEARNING, because cryonics is an undeveloped, immature, and above all, experimental technique. I signed up with the Cryonics Society of New York (CSNY) when I was 15 years old. CSNY is long, long gone and I’ve been signed up with 2 other organizations that have vanished. If you can’t keep learning until old age or “death” overtakes you, you are unwilling to do so, or you are an idiot, then cryonics is not for you.
And because cryonicists are the most rabid and intense of the life extensionists, you will also soon learn that they are at the absolute edge of emerging science in this area. In other words, you stand to be the first to know about newly developed and developing technology to combat aging. That can either “kill you or cure you, “depending upon how good your judgment is.
Finally, non-cryonicists, because they have the view of cryonics as a developed product (like an automobile or a light bulb) have a similarly inaccurate and warped view of the odds. The odds of the Titanic sinking with the loss of 1517 lives were 100% on 15 April 1912. But, what if the Titanic were to have taken, say, 48 hours to sink? Depending upon how the passengers and crew behaved in that interval, the number of survivors might have gone way up, or way down.
There were a lot of smart people on board the Titanic—very clever and very inventive people. But they were panicked, they were dealing with a panicked mass of passengers, and they had very little time to react. Given 48 hours, and the willing participation of the best minds aboard that ship, how many people need have died, or would have died? Were there ways, other than the optimal loading of the inadequate number of lifeboats that would have saved lives? Would clothing those passengers consigned to the icy sea in multiple layers of clothing saturated in grease, shortening, or oil, attaching them to life-ropes, and rotating them in and out of the lifeboats, have saved additional lives? What kind of makeshift lifeboats or floating platforms could have been made on an expedient basis from materials on the ship, allowing additional passengers to remain afloat out of the freezing water?
THAT is the position of cryonics and cryonicists. The odds are not fixed to those calculated at any given point in time, because you are NOT carting off a discrete product to screw into your lamp, or to process your words, or to play your games on. YOU set the odds of success or failure to an amazing degree. [You also do this, to a tiny degree, for the success or failure of the company that you buy a light bulb or a computer from.] Cryonics is thus an ACTIVIST proposition. Customers can, of course, be customers if they insist. But in cryonics, as in any other market transaction (perfected or experimental) you get what you pay for. In the case of cryonics, the fees required for success are not even remotely reducible to cold hard cash alone. It’s going to all the composure, good judgment and raw intelligence we can muster to escape the sinking ship fate has consigned us to and make it that far shore where we can continue our journey through life, indefinitely.
I’ll try to keep my response brief:
1) I respect the desire for precision in the use of words, and I understand that each culture has its own nomenclature and rules.Those here that I have seen so far seem eminently reasonable.
2) I have no interest whatsoever (and haven’t for many years) in persuading anyone to sign up for cryonics—including friends and family. While it is an understandable error, my purpose here is not to convince, proselytize, or recruit, but rather to identify minds that are useful to my current endeavor. They will not need persuasion—they will ‘know the lion by his paw.’
3) Forgive my levity, but in urging mono-topical posts of short duration, you pointed me to three dissertations dealing with a range of subjects within each essay, the shortest of which was ~1,400 words and the longest of which was 2,700 words—not including commentary.
4) For the record, I use the word disease in the context your writer specified: as .something unusual, abnormal, and I would add, deleterious to the normal functioning and survival of the organism. I know little about computing and have even less aptitude to learn. I use the word malware as software that damages or destroys data that the computer’s owner doesn’t want destroyed or degraded. I would add that given my predicament, when that happens it is a complex, difficult and thoroughly unpleasant thing to sort out which generally requires my machine spend time in “stasis” until the appropriate expertise can be brought to bear.
5) My posts here have been mostly confined to the subject of cryonics and were never intended to continue. I’ve really enjoyed the discussion and I’ve found this an interesting and rewarding forum. Many thanks!
