It seems to me that Miller's argument is just a vast argument from
incredulity because there's so much unknown about brain functioning and the

There might be other hurdles, even ones that make uploading (and
downloading) impossible, but much of this seems overly pessimistic in terms
of how long it will take to either successfully achieve this or find out
there's some fundamental issue with doing it.

I haven't followed the research closely, but I'd still like to see a higher
animal -- an adult mammal would be my gold standard -- recovered with
intact memories from cryopreservation. What is the state of the art here?
