In considering the pros and cons of cryonics, has anyone addressed the possibility of being revived in an unpleasant future, for instance as a "torture the infidel" exhibit in a theme park of a theocratic state? I had some thoughts on the issue but figured I would see what else has been written previously.
My bigger worry is more along the lines of "What if I am useless to the society in which I find myself and have no means to make myself useful?" Not a problem in a society that will retrofit you with the appropriate augmentations/upload you etc. and I tend to think that is more likely that not, but what if, say, the Alcore trust gets us through a half-century-long freeze and we are revived, but things have moved more slowly than one might hope, yet fast enough to make any skill sets I have obsolete? Well, if the expected utility of living is sufficiently negative I could kill myself and it would be as if I hadn't signed up for cryonics in the first place, so we can chalk that up as a (roughly) zero utility situation. So in order to really be an issue, I would have to be in a scenario where I am not allowed to kill myself or be re-frozen etc. Now, if I am not allowed to kill myself in a net negative utility situation (I Have no Mouth and I Must Scream) that is a worst case scenario, and seems exceedingly unlikely (though I'm not sure how you can get decent bounds for that).
So my quick calculation would be something like: P("expected utility of living is sufficiently negative upon waking up")*P("I can't kill myself" | "expected utility of living is sufficiently negative upon waking up") = P("cryonics is not worth it" | "cryonics is successful")
It's difficult to justify not signing up for cryonics if you accept that it is likely to work in an acceptable form (this is a separate calculation). AFAICT there are many more foreseeable net positive or (roughly) zero utility outcomes than foreseeable net negative utility outcomes.
