I agree the fact that current cryonics practice is not optimised for revival is extremely strong Baysian evidence (for me at least) that most cryonicists on these forums are considerably more likely to be signalling than rationally trying to live forever. I would add into that the well known problem of 'cryo-crastinating', which is hard to explain if pro-cryo individuals are highly rational life-year maximisers, but extremely easy to explain if people are willing to send a 'pro-cryo' signal when it is free, but not when it is expensive.

On the other hand, I am convinced at least some cryonics advocates will find a discussion on cryonics strategy genuinely useful and important, and since I was reading about cryonics anyway I thought I would fill what I considered to be a gap in the debate landscape.
