I know nothing about gene therapy, but I would imagine that replacing
neurons in the brain n by n is harder than copying the consciousness
into a computer. That said, one is a field I'm interested in and one
isn't, so that may explain my position.

Agreed, I don't think cryogenics is the "best" way of sustaining life
(but I mean, by definition almost it's a short term solution, and for
that I suppose it does do it's job, just as yet unproven?).

Replacing body parts with machine parts is probably pretty promising,
agreed. But doing the same thing to the brain is pretty interesting. I
don't know what the research in that area is. Maybe there are
interesting things happening there; it would be interesting to learn
