I suppose the article does a good job answering some of the common objections, but I still think the most important thing that's stopping people from signing up is the fact that they just don't care: after all, life sucks, but at least then you die.

That said, there is one argument that I find kind of powerful that articles like this don't usually touch on (for somewhat obvious reasons): the point made in, for example, the preface to the finale of the Ultimate Meta Mega Crossover, that if we actually live in an infinite multiverse/many-worlds/nested simulverse/etc, we may be bound to find ourselves resurrected by someone eventually anyways, and cryonics could be a way to try to make sure that someone is friendly.

I'm not really sure what to make of that argument though. I wonder if there's anybody who's signed up because of reasons like that, despite not having any interest in cryonics in general?
