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!
This is from my book Singularity Rising:
I have encountered many of the same objections to cryonics in the numerous conversations I have had on the subject, and I’m going to assume that you object to cryonics for one or more reasons I have heard before. Below this paragraph is a list of cryonics objections, and beneath each objection is a question. For reasons that either I will provide or should seem obvious, answering any question in the affirmative means that its corresponding objection shouldn’t block you from joining the cryonics movement.
Objection 1: Cryonics is unnatural.
Question 1: Would you support a law prohibiting all medicine not used by our hunter-gatherer ancestors?
Objection 2: Once you have died, you are dead.
Question 2: You fall into a lake while ice skating, and your body quickly freezes. A year from now your body thaws out and for some crazy reason, you think, look and act just as before. Are you alive?
Objection 3: Even if cryonics works, the “person” that would be revived wouldn’t really be me.
Question 3: Were you alive ten years ago?
If you answered yes, then you are not defining “you” by the physical makeup of your body, because almost none of the atoms in your body today are the same as they were ten years ago. Your body has undergone many changes over the last decade, meaning that if you still identify as you, you must be defining yourself by some broad structure and not merely by the exact arrangement of the molecules that compose “you.”
Also, imagine that a year after joining Alcor, you wake up one morning in a hospital bed, and see the smiling face of your (now much older) child. Although thirty years has passed since you died in your sleep, no subjective time has transpired, and your body has the exact same look and feel as it did before you went to bed. Indeed, had Alcor placed you back in the room in which you died, you would think today was a normal morning. Are you still you? Are you glad you signed up with Alcor?
Furthermore, consider two 40-year-olds named Tom and Jane. Tom legally dies in 2020, is cryogenically preserved, and is then revived in 2045 by a process that restores his body and brain to the condition it was in before he legally died. Jane survives to 2045. The Tom of 2045 is vastly more similar to the Tom of 2020 than the Jane of 2045 is to the Jane of 2020, as the Jane of 2045 has undergone twenty-five extra years of aging and life experience. So if you believe that Jane has stayed Jane over the time period, then you should think that the pre-cryonics Tom is the same as the post-cryonics one.
Objection 4: I don’t want to wake up a stranger in a strange world.
Question 4: While driving, you get into an accident. When you wake up in a hospital, an FBI agent tells you that the son of a Mafia leader died in the accident, and although the accident wasn’t your fault, the leader will hold you responsible. If the Mafia thinks you survived the accident, it will kill you. The agent confesses that the Mafia has infiltrated the FBI, and so the government will never be able to protect you. The agent provides one option for survival. He will fake your death, and make people think your body was burned beyond recognition. The agent will then give you a new identity, and transport you to another country, one very different from your own. You will never be able to contact any of your old friends or family again, because the always suspicious Mafia will monitor them. Do you accept the agent’s offer?
Objection 5: If revived, I wouldn’t have any useful skills.
Question 5: You have a fatal disease that has only one cure, but this cure costs $1 billion, which you can't possibly raise. NASA, however, makes you an offer. The space agency is launching a rocket that will travel near the speed of light. Because of Einstein’s theory of relativity, although the mission will take you only one subjective year to complete, when the rocket returns to Earth, one thousand years will have passed. Because you are the most qualified person to fly the rocket, NASA will pay the cost of your disease’s cure if you accept the mission. Do you accept? .
Also, you are only likely to get revived in a friendly rich world.
Objection 6: The people who revive me might torture me.
Question 6: If you knew an intelligence explosion would occur tomorrow would you commit suicide today to avoid the chance of being tortured?
Objection 7: I don’t cherish my life enough to want to extend it with cryonics.
Question 7: You will die of cancer unless you undergo a painless medical procedure. Do you get the procedure?
Objection 8: It would be morally superior for me to donate money to charity rather than spending money on cryonics.
Question 8: Same as Question (7), but now the operation is expensive, although you can afford to pay it.
Objection 9: It’s selfish of me to have more than my fair share of life, especially since the world is overpopulated.
Question 9: Same as question (7), except that your age is well above the length of time the average human lives.
Objection 10: I believe in God, the real one with a capital G, not an extremely smart artificial intelligence. I don’t want to postpone joining him in the afterlife.
Question 10: Same as Question (7).
Also, even the extra million years of life that cryonics might give you is nothing compared to the infinity you believe you will eventually spend in heaven. If you believe that God wants you to spend time in the physical universe before joining him, might he not approve of you using science and reason to extend your life, so you can better serve him in our, material world?
Many faiths believe it’s virtuous to have children, raise these children to understand God, and then hope these children beget more children who will carry on the faith. If there is a God, he appears to have started us out on a tiny planet in an empty universe. People who make it to the Singularity would likely get to “be fruitful and multiply”, and populate God’s universe. (Don’t worry if you are past childbirth age: any technology that could revive the cryogenically preserved could be used to help you have children.)
Objection 11: If people find out I have signed up for cryonics they will think I’m crazy.
Question 11: Same as Question (7), but now most people think the type of operation you will get is crazy.
The stigma of cryonics is real and has even made this author nervous about outing himself, for fear that it might make it harder for me to find alternative employment, should I choose to leave or get fired from Smith College.
Objection 12: Cryonics might not work.
Question 12: Same as Question (7), but now the procedure only has a 5% chance of saving your life.
Here is my final question for you:
One minute from now a man pushes you to the ground, pulls out a long sword, presses the sword’s tip to your throat, and says he will kill you. You have one small chance at survival: grab the sword’s sharp blade, throw it away, and then run. But even with your best efforts, you will probably die. Do you fight?
I'd say the most important objection to cryonics is the one you raise last, and only spend 1 line on. As a result your entire list seems rather weak. Because it's not just that cryonics has a low chance of working. If cryonics was free I'd sign up tomorrow, low chance be damned. But it isn't free, it is in fact very expensive.
So let's rephrase your question 12: You have a rare fatal disease. There is a complicated medical procedure that can cure you. The good news is that it is painless and has no side effects. The bad news is that it costs $200,000 and has only a 5% chance of working.
I'd expect many people would still say yes, but also many people would say no.
And a 5% chance of cryonics working seems hopelessly optimistic to me. So let's make that a 0.0000001% chance of working. Suddenly it seems like a pretty lousy deal. Do you think any rational person would still say yes?
