Can you see how this would be a problem for the entire digital
uploading argument if functional substitution cannot occur in a
strictly classical way, for example by strictly classical level
measurement of brain structure? Any dependence of consciousness on
quantum entanglement will prevent any form of digital substitution.
This is not correct. It would only make the comp subst. level
lower, for we would need to Turing-emulated the entire quantum
system. What you say would be true if a quantum computer was not
Turing emulable, but it is. Sure, there is an exponential slow-
down, but the UD does not care, nor the 'first persons' who cannot
be aware of the delays.
An exponential slowdown may be OK if you're substituting for the
whole world, but having a part of my brain running much slower would
be a good reason to say no to the doctor.
In step seven you don't need no more to say yes to the doctor. You are
in a universe with a running UD. It makes notably all the quantum
computations leading to your current state, and their many
continuations. And there, you can't be aware of the exponential slow
Step seven eliminates the doctor, and replaced it by a robust universe.
Step eight eliminates the robust universe.
