OK. So we can perhaps drop out the very idea that there is a "physical
run". I agree with
Hal Finney view of the accidental running. Consciousness is attached to
states together
with their relative histories. Consciousness will then be related to the
measure one
continuations ... if the laws of physics can be derived from that. If not:
comp is false.
And this makes comp (in principle) testable (experimentally refutable).
