OK. It is a reductio ad absurdo. It assumes that consciousness
supervenes on the physical activity of a brain (Phys. Sup.), it shows
that it leads to the fact that consciousness suoervenes on a movie
"qua computatio", and this is considered as an absurdity, and so it
concludes that Phys. Sup is false.

Why? Consciousness supervenes on the computation(s), not on his
physical implementation, be it with record or with the original modules.

The physical supervenience. Consciousness does not supervene on any
implementation "in particular" of a computation. It supervenes on all
(immaterial) computations going through the (relevant) states. This is
in Platonia.
Tell me if I miss something, but it seems to me there is no problem
here. It is just, again, a problem if you believe in some physical
supervenience.
Best,
Bruno
