Hello Bruno,
I must admit you have completely lost me with MGA 3.
With MGA 1 and 2, I would say that, with MEC+MAT, also the the
projection of the movie (and Lucky Alice in 1) are conscious - because
it supervenes on the physical activity.
MEC says: it's the computation that counts, not the substrate.
MAT says: we need some substrate to perform a computation. In MGA 1 and
2 we have substrates (neurons or optical boolean graph that performs the
computation).
Now in MGA 3 you say:

Agreed.

We can remove those optical boolean nodes which are not relevant for the

but no! Then we wouldn't have a substrate anymore. You are dropping MAT
at this step, not leading MEC+MAT to a contradiction.

We can talk about this part after I understand why you can drop our
optical boolean network *grin*
