Dans un courrier dat  du 02/08/01 11:02:04 Paris, Madrid (Heure d' t ), 
 a  crit :

<< 
 We don't have to repair all the molecules. We don't even necessarily have to 
 understand the problem in full detail. We can sometimes cure a disease 
 without understanding it, and we can probably repair a brain without fully 
 understanding it. 
 
 I am not a short-term optimist about fully and immediately reversible 
 cryostasis, but I believe that CI research under Dr. Pichugin, and the work 
 of others, will continue to yield important improvements. I also continue to 
 think that even most of our "bad" cases are not hopeless, and that Mr. 
 Bozzonetti has greatly overstated the difficulties.

I think we must start with what we have, so indeed Dr. Pichugin's work is 
usefull. The problem is that what it does is in the biochemical domain and 
that will solve problems for near reversible conservation, what Alcor seems 
commited to. For current case, I think that way wiill be insufficient. 
Nanotech will be requested at both scale: micro surgery with microtechnology 
and molecule repair at atom scale.  The first may be a by-product of 
electronics industry, the second is something new.

As I see it, CI  and you Bob, are long term optimist: you think all problem 
will be solved in theyr time. I agree with that. On the other hand, I think 
we must not say the solution is at the street corner, if not, when someone  
discover that  there is another corner after the one we see they throw away 
all the cryonics idea and put some strong word agains long range visionaries 
(The Letil syndrome).

So I restate my viewpoint:
-Yes, we must do research now, this is the most useful thing to do.
-Yes, that research must start with what we have and Dr. Pichugin's work is 
what must done now.
No, that will not bring to us a general solution, only reversible 
cryopreservation in X years, not a way to get out of the fridge current 
patients.
 -For present day cryonics *user*, the first solution will be some upload 
technology. For it, indeed, we not need to know how the brain works, we need 
only two things:
A big processing information system, a classical computer or something else, 
and
A brain reader. That is why I am interested in that technology.

To get out of LN2 the original flesh, there will must be an atom scale nano 
tech capability, and this one has a big computing problem as noted before.
