Cryonics: A Glass-state Time Travel

Frozen to Life
What if we gave people a way to escape absolute death at the end of their biologically-allotted lifespans? Wouldn’t many of them jump at it? Of course, and they do, and have been for some time now. Religionists believe that the metaverse (or whatever they wish to call the whole macro-everything, including all the ‘spiritual’ bits) is neatly ordered to deliver them into immortality, just in time. There’s no mechanism for this. It just happens.
That’s an amazing technology – no mechanism, no physical processes, no messy cause and effect to worry about. Religionists, however, don’t consider this a technology. It’s beyond technology and little human tinkerings like that. Something else does the miraculous transmutation from decay-prone physical stuff to eternal ethereal stuff – something evidently a lot smarter than we are.
The religionist route is an unfounded one, to say the very least.
So, what might work if you want to avoid absolute death? First, you need to accept your existence as a host of atoms in particular configurations. Second, you need to think about ways to arrest biological decay, which is just the chemical reactions that happen when the specific set of constraints we call life no longer apply. As Brian Wowk discusses in his essay Medical Time Travel, the Arrhenius equation shows us that chemical reactions stop when temperature drops low enough (-196 °C, just below the boiling point of nitrogen, will suffice for our purposes). Done correctly, with the right concentration of antifreeze-type cryoprotectants, your ‘dead’ brain and its surrounding tissues will undergo ‘glass-state’ vitrification after suspension in liquid nitrogen. Third, armed with this information, you need to act. It’s unlikely that anybody else is going to set up the circumstances for your eventual glass-state transition, so it’s down to you.
In information-theoretic terms, immortality is already possible. It just isn’t much fun, because you can’t be conscious of anything. Bad and extant, good and gone, you hang on the precipice tip of an unclosed infinity symbol. With your molecular interactions halted, nothing happens. Time yawns, and down its craw you silently fall. Nobody knows how to resurrect a person from this immortal abeyance. Some have theories, some even incipient skills and tools, but no one yet knows how to trigger the temporal gag reflex that will cough you out and close the sigil.
But think on it. Think on the potential. The glass-state time-traveler is indeterminate, undissipated, untruncated. Her death was not information-theoretic death. She is orders of magnitude less dead than the conventionally-erased many.
Skepticism about her possible revival amounts to this: because we cannot imagine how she might be revived, we cannot imagine how she might be revived. Might it take nanobots, substrate-independence tech, scanning neuromorphic arrays, advanced connectomic inference, molecular assemblers? Who knows? Perhaps all of these, perhaps none. No matter. She has the luxury of time. Only if abandoned and allowed to decay (or if our race extinguishes itself before the necessary technology arises) will her problem become terminally insurmountable.
This potential solution to the problem of absolute death defies established human conventions of death and corpse-disposal. It triggers ‘cognitive dissonance’ and repugnance reactions. Scientist Leon Kass finds ‘wisdom’ in the human repugnance response. On cryonics, I neither feel it nor find it wise. Post-mortem cryoprotective abeyance is a logical choice. Nevertheless, the heavy blinders of repugnance and convention still screen this from most. And we ‘cryonicists’ do it to ourselves; we are far from immune to the emotional and existential (for a few, even ‘spiritual’) turmoil our mortal decision may cause.
‘Cryonauts’ are simply mute, liminal dwellers on an unknown threshold. Not living, not dead; not formerly crazy – nor necessarily selfish, altruistic, or pioneering. Just – for the love of hope and reason – not irretrievably lost.
About the Author:
D.J. MacLennan
D.J. MacLennan is a futurist author who lives on the Isle of Skye, Scotland. He wrote two chapters of the recently-published cryonics anthology The Prospect of Immortality – Fifty Years Later. His new book Frozen to Life: A Personal Mortality Experiment is due for release at the end of August 2015.
Every so often, I see a blog post about death, usually remarking on the death of someone the writer knew, and it often includes sentiments about "everyone is going to die, and that's terrible, but we can't do anything about it have so we have to accept it."
It's one of those sentiments that people find profound and is often considered Deep Wisdom. There's just one problem with it. It isn't true. If you think cryonics can work, as many people here do, then you believe that people don't really have to die, and we don't need to accept that we've only got at most about a hundred years and then that's it.
And I want to tell them this, as though I was a religious missionary out to spread the Good Word that you can save your soul and get into Christian Heaven as long as you sign up with Our Church. (Which I would actually do, if I believed that Christianity was correct.)
But it's not easy to broach the issue in a blog comment, and I'm not a good salesman. (One of the last times I tried, my posts kept getting deleted by the moderators.) It would be a lot better if I could simply link them to a better sales pitch; the kind of people I'm talking to are the kinds of people who read things on the Internet. Unfortunately, not one of the pro-cryonics posts listed on the LessWrong wiki can serve this purpose. Not "Normal Cryonics", not "You Only Live Twice", not "We Agree: Get Froze", not one! Why isn't there one? Heck, I'd pay money to get it written. I'd even pay Eliezer Yudkowsky a bunch of money to talk to my father on the telephone about cryonics, with a substantial bonus on offer if my father agrees to sign up. (We can discuss actual dollar amounts in the comments or over private messages.)
Please, someone get to work on this!
