The social ones. I actually probably value this higher than 1. Explaining to my loved ones my decision, having to endure mockery and possibly quite strong reactions
You have to play a Long Game here, something I find increasingly easy to do as I have reached my 50's. I told my original "loved ones" - my mother, my father (divorced from the former), and my sister - about cryonics a quarter century ago. They all considered it weird, but then whatever problems that might have caused me tend to correct themselves with time. My father died last October, for example, and now his ashes reside in a veterans' cemetery in Arkansas.
As for other "loved ones," I have had no candidates for that role so far. (Don't sign up for cryonics for the dating prospects, in other words.)
Every so often, I see a blog post about death, usually remarking on the death of someone the writer knew, and it often includes sentiments about "everyone is going to die, and that's terrible, but we can't do anything about it have so we have to accept it."
It's one of those sentiments that people find profound and is often considered Deep Wisdom. There's just one problem with it. It isn't true. If you think cryonics can work, as many people here do, then you believe that people don't really have to die, and we don't need to accept that we've only got at most about a hundred years and then that's it.
And I want to tell them this, as though I was a religious missionary out to spread the Good Word that you can save your soul and get into Christian Heaven as long as you sign up with Our Church. (Which I would actually do, if I believed that Christianity was correct.)
But it's not easy to broach the issue in a blog comment, and I'm not a good salesman. (One of the last times I tried, my posts kept getting deleted by the moderators.) It would be a lot better if I could simply link them to a better sales pitch; the kind of people I'm talking to are the kinds of people who read things on the Internet. Unfortunately, not one of the pro-cryonics posts listed on the LessWrong wiki can serve this purpose. Not "Normal Cryonics", not "You Only Live Twice", not "We Agree: Get Froze", not one! Why isn't there one? Heck, I'd pay money to get it written. I'd even pay Eliezer Yudkowsky a bunch of money to talk to my father on the telephone about cryonics, with a substantial bonus on offer if my father agrees to sign up. (We can discuss actual dollar amounts in the comments or over private messages.)
Please, someone get to work on this!
