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

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'?
