My consciousness supervenes on my brain as it is now —
With mechanism, and I think with QM, your brain is only a map where you can find what realised your computation. You have as much brain (at least) than there is electron position available in each orbital. If the quantum determines the substitution level, i.e. we would need the precision permitted by the Heisenberg Uncertainties, then what I say above would be literally true. You have an infinity of “apparent brains” distributed in the (sigma_1) arithmetical reality, and your consciousness (direct memories + direct anticipation) depends on this. > it does not supervene on other possibilities.

Assuming Mechanism: that is impossible.
