You are right, at least when, for the sake of the argument, we  
continue to keep MEC and MAT, if only to single out, the most  
transparently possible, the contradiction.
Let us consider your  "lucky teleportation case", where someone use a  
teleporter which fails badly. So it just annihilates the "original"  
person, but then, by an incredible luck the person is reconstructed  
with his right state after. If you ask him "how do you know how to tie  
shoes", if the person answers, after that bad but lucky  
"teleportation" "because I learn in my youth": he is correct.
He is correct for the same reason Alice's answer to her exams were  
correct, even if luckily so.
Suppose I send you a copy of my sane paper by the internet, and that,  
the internet demolishes it completely, but that by an incredible  
chance your buggy computer rebuild it in its exact original form. This  
will not change the content of the paper, and the paper will be  
correct or false independently of the way it has flight from me to you.
In the bad-lucky teleporter case, even with MAT (and MEC) it is still  
the right person who survived, with the correct representation of her  
right memories, and so one. Even if just "luckily so".
MGA 2 then shows that the random appearance of the lucky event was a  
red hearing, so that we have to admit that consciousness supervenes on  
the movie graph (the movie of the running of the boolean optical  

Of course I don't believe that consciousness supervene on the physical  
activity of such movie, but this means that I have to abandon the  
whole physical supervenience. I will read the other posts. I think  
many have understood and have already concluded. But from a strict  
logical point of view, perhaps some are willing to defend the idea  
that the movie-graph is conscious, and, in that case, I will present  
MGA 3, which is supposed to show that, well, a movie cannot think,  
through MEC (there is just no computation there). Of course, the movie  
has still some relationship with the original consciousness of Alice,  
and this will help us to save the MEC part of the physical  
supervenience thesis, giving rise to the notion of "computational  
supervenience", but this form of supervenience does no more refer to  
anything *primarily* physical, and this will be enough preventing the  
use of a concrete universe for blocking the UDA conclusion.
