>Same with the cryogenic. You should consider the possibility that freezing you with our poor technology can make you unrecoverable, while some other technology could allow you to be saved eventually.
Yes, and that's rational. If there's another preservation technology that's better than cryopreservation, we should adopt that. There's nothing irrational about that. You just need to first invent such technology, and then provide evidence that it's better than current vitrification tech.
This has happened in the past. A few decades ago the preservation method was changed from freezing to vitrification, after vitrification was shown to be better.
