I don't understand the point. Ideal cryonics is about turning CNS tissue into
cryogenic glass, proceeding as quickly as possible while introducing the least amount
of artifacts. The result is a static block, with no relevant rate of change.

Once you're there, you're golden. It doesn't matter when and whether you 
process stuff in tiny increments, or disassemble and reassemble the entire 
thing in one fell swoop, so interim it only exists as bits. The process is
completely transparent but for the final result.

Because time is of no relevance on that last leg of the journey, we can
assume essentially perfect information extraction methods. Given the
tremendous loss of information on that initial, crucial stage we should frankly
look there for potential show-stoppers (there are several candidates there,
which typically don't attract attention for some strange reason; probably
because they're perfectly boring, and require low-tech legacy methods to be
addressed, which are considering bor-r-ing).

Repairing the brain in vivo in situ requires medical nanotechnology. I don't
think anyone on this list will benefit from that (with the possible exception
of very young radical CR practitioners, and/or working personal molecular
therapies for life extension). Once again, I'm not holding my breath.
