Do you think its just quackery or something that could legitimately be possible one day? (once the technology advances)
Obviously I’m skeptic of it but I’d be lying if I said I wasn’t intrigued.
Here are some quick videos explaining the topic for those who may be unfamiliar
If anyone familiar with the “science” of cryonics has any book recommendations for me it would be greatly appreciated.
Thank you in advance.
I’m familiar with cryonics and have been following it for decades. Let me first point out that there is nothing in physics that prohibits this from working. It is a technical challenge. Frogs freeze every winter in Canada and Alaska. They are able to do this using natural cryoprotectants that prevent freezing damage from ice crystals forming inside cells. Freezing damage wreaks havoc at the cellular level. All cryonics companies use cryoprotectants now but they have their own set of issues, mainly toxicity. With nanobots and sufficient computing it is possible to fix toxicity issues, freezing damage and the original cause of death(as well as aging). We can freeze, but we don’t have the tech to repair ... yet. If we did, we wouldn’t need to be frozen in the first place.
Let’s talk about freezing damage for a second. Imagine dropping a crystal vase on concrete and seeing it shatter. In years past it would have been impossible to imagine reassembling the vase. But today we could scan all the pieces and have a computer figure out how the pieces fit back together. The problem of reversing cellular damage due to freezing is very much the same but far more complex. Keep in mind that computing power increases exponentially and soon we will be able to virtually reconstruct a frozen brain if we have sufficient non destructive scanning capability. Time is your friend. What if it takes a year for a computer to reconstruct your brain? Big deal… you’re frozen. A minute feels the same as a century when you’re in stasis.
I can talk more about any of these aspects at the layperson level if you like. Let’s talk about some social objections.
Overpopulation. There are at least a half dozen reasons why this is not an issue but let me point out that the assumption is that we will always stay here on Earth(and always have children). The universe is huge. If I can have an indefinite lifespan, I’d want to travel. We are already making plans to colonize mars. If H. Sapiens is to survive we will have to colonize other star systems. This is a fact.
Discontinuity. Being disconnected in time and socially. This is obviously a personal preference and I can’t judge others but personally I’m old enough and experienced enough to know that A. I can adapt and make new friends. B. I don’t keep in touch with people from 20 years ago, except for maybe family C. I’ve lost a lot of people to death so separation happens anyway, get used to it. The other thing people seem to have a blind spot about when it comes to continuity is this, what if all your friends and family were also cryopreserved? Then you wouldn’t lose them. For some reason people who voice the discontinuity objection don’t ever contemplate this scenario.
Most people do not believe a thing is possible until it has already happened. This has been true of airplanes, automobiles, submarines, home computers, cell phones, radio, and hundreds more technologies that we take for granted every day. This doesn’t mean people are stupid, it’s just human nature to not be able to see beyond your current framework of reality.
As far as non existence is concerned. I didn’t exist for billions of years and that doesn’t bother me. The knowledge that I will not exist again doesn’t scare me for the same reason. I don’t fear death, I love life and want as much of it as I can get.
