there is no evidence of it ever being done successfully.
There is evidence that cryonics preserves brain structure to some extent, which, coupled with the fact that people are brains, constitutes Bayesian evidence that cryonics suspensions performed up to this point were successful (that is, information-theoretic death didn’t happen). What you require as evidence in this case might be a clear-cut demonstration of a cryonics patient getting revived. However, if we already knew how to revive people we wouldn’t bother with cryosuspension in the first place. You can’t, at this point in time, reasonably expect that kind of evidence, even if cryonics works perfectly.
Freezing things makes water expand and burst the fragile parts of your brain.
Correctly performed cryosuspension involves vitrification instead of freezing.
You didn’t say anything explicitly wrong except vitrification can’t work 100% yet, ice crystals are still formed. information-theoretic “death” may not have happened but the claim that recovery may be possible in the far future is a seriously dubious, so is the evasive attempts of beleivers like gwern to maintain this beleif without backing it up.

What exactly is your argument here? Why do you think vitrification doesn’t work, especially given you hadn’t heard of it until a few minutes ago?
Are you now shifting your argument to ‘yes, vitrification works to preserve everything, but we won’t be clever enough to make any use of the preservation’?
