Do you agree with the quantum physics sequence? This is the big reveal:

If you can see the moments of now braided into time, the causal dependencies of future states on past states, the high-level pattern of synapses and the internal narrative as a computation within it - if you can viscerally dispel the classical hallucination of a little billiard ball that is you, and see your nows strung out in the river that never flows - then you can see that signing up for cryonics, being vitrified in liquid nitrogen when you die, and having your brain nanotechnologically reconstructed fifty years later, is actually less of a change than going to sleep, dreaming, and forgetting your dreams when you wake up.

You should be able to see that, now, if you've followed through this whole series. You should be able to get it on a gut level - that being vitrified in liquid nitrogen for fifty years (around 3e52 Planck intervals) is not very different from waiting an average of 2e26 Planck intervals between neurons firing, on the generous assumption that there are a hundred trillion synapses firing a thousand times per second. You should be able to see that there is nothing preserved from one night's sleep to the morning's waking, which cryonic suspension does not preserve also. Assuming the vitrification technology is good enough for a sufficiently powerful Bayesian superintelligence to look at your frozen brain, and figure out "who you were" to the same resolution that your morning's waking self resembles the person who went to sleep that night.
