I have always disagreed with this. The movie+broken gates is still a
computation, just a rather simple one. Playing a movie in (eg)
SMPlayer is still running a computation.

yes, but in the MGA we know the content of the consciousness (usually a dream where the person is flying). So a human dream would supervene on a very simple simple computation, which can be made arbitrary simple. Would say yes to a doctor who suggest to replace your brain with a simple clock?




As I see it, the argument still relies on an intuition that the
movie+broken gates computation cannot support consciousness. It is an
intuition pump, not a proof, and consequently a weakness of the MGA.

MGA tackles the application of a theory to a reality. So it cannot leads to a proof, as we can prove nothing about reality, and so we do need some occam razor and intuition pump. The argumpent here can defeat all theories.



And static vs dynamic is a red herring, because as Bruce quite rightly
points out, a static block Multiverse contains at least one, and by
definition all possible conscious entities.

OK. Like arithmetic. Again the consciousness is not in any static elementary things, but in the static relations rich enough the give the internal dynamics, and, with luck (= if comp is true) the right relative measures.
