The point is not that neurological processes can't be modeled

that illustrates a feedback structure. These neurons could be
replaced by flip flop systems and other electronic. In that way
this system could be modeled. My main point is there is a
distinction between the territory and the map. Feynman also made
the quip that simulation is like masturbation; it is fine until
you start thinking it is the real thing.

But isn't consciousness different? A simulation and the real
thing must be identical if "the real thing" is information processing.

I certainly would not bet my life on this. I would not voluntarily
terminate my life early with the idea computational brain states can
be mapped into a computer. Is consciousness something capture in the
Church-Turing thesis? That to me is a very problematic assumption.
I give it half a chance this will go the way the cyrogenic movement
went. In the 1970s there was a big hype about preserving bodies in
liquid nitrogen with the idea of reviving them. There were some
clients, but the whole thing hit the reef financially and with growing
criticisms about the scientific and medical efficacy of this the
bodies were eventually buried. There have been follow on programs with
this, but I think it has few takers.
In 20 years in my 70s I might prefer to do things, even gaze at
sunsets etc, rather than cast another 10 to 20 years of life onto this
promise I will "rise again." For all I know this could just end up as
a big hustle where there are those who take my money and I and up as
worm food anyway.
If it just doesn't work and you get buried, it's just some money
lost...you didn't have a choice about betting on life vs death. I'd be
more concerned that it would work and you'd be revived in a time when
human brains had been far surpassed and were considered only useful for
operating equipment in mining or cleaning office spaces.
