Not at all, I only assume a brain needs an external world to be aware of.
Either what you add to the brain is Turing emulable, and that means
you are just lmowering the substittution level, and the reasoning I
presented still follows (as he used the "generaluzed brain").
That misses the point. It's not lowering the substitution level, it's
also expanding the scope of the emulation to include the environment.
Although brains are relatively isolated except for efferent and afferent
nerve signals, they are not absolutely isolated. They depend on
decoherence in order to function as quasi-classical computers.
Decoherence depends on interactions with the environment.
But if the emulation must be expanded to include an evironment it is not
longer just an emulation of a brain, it is an emulation of a brain in a
world. The "physics" of that world is essential to the emulation.
