You are correct regarding expected-utility calculations, but I make an epistemic separation between plausabilities and probabilities. Plausible means something could happen without contradicting the other things I know about reality. Probable means there is actually evidence something will happen. Expected value deals in probabilities, not plausibilities.

Now, given that cryonics has not been seen to work on, say, rats, I don't see why I should expect it to already be working on humans. I am willing to reevaluate based on any evidence someone can present to me.

Of course, then there's the question of what happens on the other side, so to speak, of who is restoring your preserved self and what they're doing with you. Generally, every answer I've heard to that question made my skin crawl.
