My girlfriend/SO's grandfather died last night, running on a treadmill when his heart gave out.
He wasn't signed up for cryonics, of course. She tried to convince him, and I tried myself a little the one time I met her grandparents.
"This didn't have to happen. Fucking religion."
That's what my girlfriend said.
I asked her if I could share that with you, and she said yes.
Just so that we're clear that all the wonderful emotional benefits of self-delusion come with a price, and the price isn't just to you.
What kind of evidence would it take to convince you that cryonics has a small, but considerable chance of working in the future, prior to there being any successful revivals?
I don't like to deal in probabilities, but I'd reckon a successful revival of a dolphin would count. Short of that? Probably nothing, if by 'considerable' you mean 'worth spending my money on'. Things other than evidence might convince me though - like my wife wanting to sign up for cryonics for whatever fool reason.
