Sticking with the non-destructive scan + terminal illness scenario: before the scan is carried out, do you anticipate (i) experiencing being reunited with your loved ones; (ii) requesting euthanasia to avoid a painful terminal disease; (iii) both (but not both simultaneously for the same instance of "you")?
Probably (iii) is the closest to the truth, but without euthenasia. I'd just eventually die, fighting it to the very end. Apparently this is an unusual opinion or something because people have such a hard time grasping this simple point: what I care about is the continuation of my inner narrative for as long as possible. Even if it's filled with suffering. I don't care. I want to live. Forever if possible, for an extra minute if that's all there is.
A copy may accomplish my goal of helping my family, but it does absolutely nothing to accomplish my goal of survival. As a matter of self-preservation I have to set the record straight whenever someone claims otherwise.
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.
