The odds of a successful cryonic revival may me one in several thousand, or five percent, or ninety percent; the error bars on the various sub-parts of the question are very broad.
But if those assumptions work out, and if at least some people placed in suspension in the near future will be successfully revived in the far future…
… then are there any useful arrangements which can be made now, which have little-to-no present cost (beyond the cryonic arrangements themselves)?
For example, if someone were to make an announcement along the lines of, “If anyone makes a promise to try to assist in my cryonic revival, and to assist me in getting myself established thereafter; then I promise to try to assist those people with their cryonic revivals, and assisting them, ahead of anyone who hasn’t made such a promise.”, then what downsides would there be to having made it? Would making it create any perverse incentives, which could be avoided? Do the potential benefits, especially the benefit of a potential increase in the odds of being revived, outweigh the potential costs?
Would it be better to make promises to specific people while one is alive, instead of making an open-ended promise? That is, I might try to convince EYudkowsky to make a mutual-assistance agreement with me personally, in hopes that one of us will one day be able to help the other; or I might make the agreement so broad that people can make their promise to help me even after I’m dead.
How large would the benefits be of unilaterally promising to help someone else, without even asking for a reciprocal promise? Or, put another way, how big would the costs be if I were to simply announce that, if it’s ever in my power, I’ll try to assist in EYudkowsky’s revival?
Does anyone care to try figuring out the Prisoner’s-Dilemma-like aspects of this, such as the probability that someone in such a pact would renege on their end of it, and how the terms could be adjusted to minimize the benefits and maximize the costs of such anti-social behavior?
