I've noticed a weird cognitive dissonance among cryonicists where they talk a good game about how much they believe in scientific progress, technological acceleration and so forth - yet they seem totally unconcerned about the fact that we just don't see this alleged trend happening in cryonics technology, despite its numerous inadequacies.

The problem of people compartmentalizing between what they think is valuable and what they ought to be working on is pretty universal. That being said, it does make cryonics less likely to succeed, and thus worth less; it's just a failure mode that might be hard to solve.
