Immortality; from the Pharaohs to cryonics

 I thought the term was cryogenics, but a feature article in the Weekend Australian Magazine (27-28 May 2023) calls the facilities that perform this process, cryonics, and looking up my dictionary, there is a distinction. Cryogenics is about low temperature freezing in general, and cryonics deals with the deep-freezing of bodies specifically, with the intention of one day reviving them.
 
The article cites a few people, but the author, Ross Bilton, features an Australian, Peter Tsolakides, who is in my age group. From what the article tells me, he’s a software engineer who has seen many generations of computer code and has also been a ‘globe-trotting executive for ExxonMobil’.
 
He’s one of the drivers behind a cryonic facility in Australia – its first – located at Holbrook, which is roughly halfway between Melbourne and Sydney. In fact, I often stop at Holbrook for a break and meal on my interstate trips. According to my car’s odometer it is almost exactly half way between my home and my destination, which is a good hour short of Sydney, so it’s actually closer to Melbourne, but not by much.
 
I’m not sure when Tsolakides plans to enter the facility, but he’s forecasting his resurrection in around 250 years time, when he expects he may live for another thousand years. Yes, this is science fiction to most of us, but there are some science facts that provide some credence to this venture.
 
For a start, we already cryogenically freeze embryos and sperm, and we know it works for them. There is also the case of Ewa Wisnierska, 35, a German paraglider taking part in an international competition in Australia, when she was sucked into a storm and elevated to 9947 metres (jumbo jet territory, and higher than Everest). Needless to say, she lost consciousness and spent a frozen 45 mins before she came back to Earth. Quite a miracle and I’ve watched a doco on it. She made a full recovery and was back at her sport within a couple of weeks. And I know of other cases, where the brain of a living person has been frozen to keep them alive, as counter-intuitive as that may sound.
 
Believe it or not, scientists are divided on this, or at least cautious about dismissing it outright. Many take the position, ‘Never say never’. And I think that’s fair enough, because it really is impossible to predict the future when it comes to humanity. It’s not surprising that advocates, like Tsolakides, can see a future where this will become normal for most humans. People who decline immortality will be the exception and not the norm. And I can imagine, if this ‘procedure’ became successful and commonplace, who would say no?
 
Now, I write science fiction, and I have written a story where a group of people decided to create an immortal human race, who were part machine. It’s a reflection of my own prejudices that I portrayed this as a dystopia, but I could have done the opposite.
 
There may be an assumption that if you write science fiction then you are attempting to predict the future, but I make no such claim. My science fiction is complete fantasy, but, like all science fiction, it addresses issues relevant to the contemporary society in which it was created.
 
Getting back to the article in the Weekend Australian, there is an aspect of this that no one addressed – not directly, anyway. There’s no point in cheating death if you can’t cheat old age. In the case of old age, you are dealing with a fundamental law of the Universe, entropy, the second law of thermodynamics. No one asked the obvious question: how do you expect to live for 1,000 years without getting dementia?
 
I think some have thought about this, because, in the same article, they discuss the ultimate goal of downloading their memories and their thinking apparatus (for want of a better term) into a computer. I’ve written on this before, so I won’t go into details.
 
Curiously, I’m currently reading a book by Sabine Hossenfelder called Existential Physics; A Scientist’s Guide to Life’s Biggest Questions, which you would think could not possibly have anything to say on this topic. Nevertheless:
 
The information that makes you you can be encoded in many different physical forms. The possibility that you might one day upload yourself to a computer and continue living a virtual life is arguably beyond present-day technology. It might sound entirely crazy, but it’s compatible with all we currently know.
 
I promise to write another post on Sabine’s book, because she’s nothing if not thought-provoking.
 
So where do I stand? I don’t want immortality – I don’t even want a gravestone, and neither did my father. I have no dependents, so I won’t live on in anyone’s memory. The closest I’ll get to immortality are the words on this blog.
