Too often I see people basing their now-decisions on the now-technology, rather than the now-measured rate of advancement of the technology.
The rate of advancement of cryopreservation technology that occurred in the past is already an ill-defined concept, very difficult to measure in a sensible way. Making extrapolations to the future is basically a random guess.
Anyway, if you think there is a chance that viable cryopreservation technology may appear within your lifetime, it seems that the best course of action would be to start investing money in low-risk assets and then sign up for cryonics if and when the technology become available, rather than making a blind commitment right now.
Naive measurements are still measurements. Personally, I would like to see more research into prediction as a science. It is difficult because you want to jump ahead decades, and five-year-out predictions have only so much value, but I (naively) predict that we'll get better at prediction the more we practice concretely doing so. I would (naively) expect that the data used to calibrate predictions would come from interviews with researchers paired with advanced psychology.
...Plotting your personal rate of advancement against the team and the field, we pre
In June 2012, Robin Hanson wrote a post promoting plastination as a superior to cryopreservation as an approach to preserving people for later uploading. His post included a paragraph which said:
This left me with the impression that the chances of the average cryopreserved person today of being later revived aren't great, even when you conditionalize on no existential catastrophe. More recently, I did a systematic read-through of the sequences for the first time (about a month 1/2 ago), and Eliezer's post You Only Live Twice convinced me to finally sign up for cryonics for three reasons:
I don't find that terribly encouraging. So now I'm back to being pessimistic about current cryopreservation techniques (though I'm still signing up for cryonics because the cost is low enough even given my current estimate of my chances). But I'd very much be curious to know if anyone knows what, say, Nick Bostrom or Anders Sandberg think about the issue. Anyone?
Edit: I'm aware of estimates given by LessWrong folks in the census of the chances of revival, but I don't know how much of that is people taking things like existential risk into account. There are lots of different ways you could arrive at a ~10% chance of revival overall:
is one way. But:
is a very similar conclusion from very different premises. Gwern has more on this sort of reasoning in Plastination versus cryonics, but I don't know who most of the people he links to are so I'm not sure whether to trust them. He does link to a breakdown of probabilities by Robin, but I don't fully understand the way Robin is breaking the issue down.
