I expect that the utility per unit time of future life is significantly higher than what we have today, even taking into account loss of social network.
Perhaps, but that's highly debatable. Anyway, my main point was that the two scenarios (bullet / cryonics) are not anywhere near being mathematically equivalent, there are a lot of differences, both in favor and against cryonics, and pretending they don't exist is not helping. If anything, it just reinforces the Hollywood stereotype of the "vulkan rationalist" who doesn't have any feeling or emotion, and that basically fails to understand what makes life worth being lived. And that's pretty harmful from a PR point of view.
Of course this asymmetry goes away if you persuade your friends and family to sign up too.
Even then it's not the case, unless everyone dies and is frozen at the same time. If I sign to cryonics, die tomorrow and am resurrected in 200 years, and my 4 yo niece signs to cryonics when she's adult and dies in 80 years and is resurrected too in 200 years, she'll still have grown without her uncle, and I would still have missed her childhood - in fact, she would likely not even remember me, and the 84-yo person she would be wouldn't be much like the one I remembered.
I think it's probably 2-10 times better in utility than the best we have today.
Perhaps. There is a lot of uncertainty about that (which compounds with the odds of cryonics working at all), and while there are possible futures in which it's the case, it's not certain at all - especially from someone from now.
But you also forget a very important point - utility for other people. Perhaps I would be happier in the future than now - but to take the same example, my niece would still miss her uncle (and that would be even much worse if I were a father, not "just" an uncle), and less utility in her childhood because of it. And I value her life more than my own.
OK, slight disclaimer, this is a bit of a joke article inspired by me watching a few recent videos and news reports about cryonics. Nevertheless, there is a serious side to it.
Many people claim that it is irrational to sign up for cryonics, and getting into the nitty gritty with them about how likely it is to work seems to turn into a series of small skirmishes with no particular "win condition". Opponents will not say,
Rather, they will retreat to a series of ever harder to falsify positions, usually ending up at a position which is so vague that it is basically pure mood affiliation and acts as a way to stop the conversation rather than as a true objection. I have seen it many times with friends.
So, I propose that before you debate someone about cryonics, you should first try to sign then up for inverse cryonics. Inverse cryonics is a very simple procedure, fully scientifically tested that anyone can sign up for today, as long as they have a reasonably well-off benefactor to take the "other side" of the bet. Let me explain.
The inverse cryonics patient takes a simple revolver with 6 barrels, with one bullet loaded and spins the barrel on the gun, then shoots themselves once in the head1. If the inverse cryonaut is unlucky enough to shoot themselves with a barrel containing a real bullet, they will blow their brains out and die instantly and permanently. However, if they are lucky, the benefactor must pay them $1 per day for the rest of their lives.
Obviously you can vary the risk, rewards and timings of inverse cryonics. The death event could be postponed for 20 years, the risk could be cranked up or down, and the reward could be increased or decreased or paid out as a future discounted lump sum. The key is that signing up for inverse cryonics should be mathematically identical to not signing up for cryonics.
As a baseline, cryonics seems to cost ~$1/day for the rest of your life in order to avoid a ~1/10 chance of dying2. Most people3 would not play ~10-barrel Russian Roulette for a $1/day stipend, even with delayed death or an instant ~$50k payout.
In fact,
Of course, I'm sure opponents of cryonics won't bite this particular bullet, but at the very least it may provide an extra intuition pump to move people away from objecting to cryonics because it's the "risky" option.
Comments and criticisms welcome.
1. Depending on the specific deal, more than six barrels could be used, or several identical guns could be used where only one barrel from one gun contains a real bullet, allowing one to achieve a reasonable range of probabilities for "losing" at inverse cryonics from 1 in 6 to perhaps one in 60 with ten guns.
2. And pushing the probability of cryonics working down much further seems to be very hard to defend scientifically, not that people haven't tried. It becomes especially hard when you assume that the cryonics organizations stick around for ~40 years, and society sticks around without major disruptions in order for a young potential cryonaut who signs up today to actually pay their life insurance fees every day until they die.
3. Most intelligent, sane, relatively well-off people in the developed world, i.e. the kind of people who reject cryonics.
4. And you believe that the life you miss out on in the future will be as good, or better than, the life you are about to live from today until your natural death at a fixed age of, say, 75.
