There seems a surprising amount of techno pessimism here. Just to take the other side I think it's very likely to succeed at least to some extent. If you just assume computing and scanning keep improving a similar amount per year to what they have been then we'll have the tech to scan and simulate for example in two or three decades.
Except that there are other things you could do with the money, some of which could potentially even give you a much greater chance of not vitrifying in the first place.
Now if you would divert all cryonics resources towards existential risk mitigations, AI or rejuvenation research, that would be a different story. But pretty soon we'd have to discuss how other resources are allocated right now, and next thing we know, we're talking politics.
If you ask me, the world can probably finance cryonics for everyone and AI research and anti-ageing research and existential risk mitigation and many other things I didn't think of, while preserving and improving our standards of living at the same time. The (huge) problem is getting our act together.
You say "talking politics" like it's a bad thing!

Well yes.
That was unintended. But it is difficult: http://wiki.lesswrong.com/wiki/Politics_is_the_Mind-Killer
