This is the ASSA (Absolute Self Sample Assumption) version of the measure problem. In this case, physicalism *does* provide a solution under the form of QM, which explains well the rarity of *THIRD person white rabbits*, through the idea of Everett + decoherence. Alas, Everett has to postulate a computationalist theory of mind, which makes unavoidable the first and third person distinction, and which, by that way, introduces the *FIRST person white rabbits*, and those 1-rabbits are not a priori eliminated through the quantum interferences; unless you derive the quantum interference from the winning general computations in the deployement of the UD work (UD = Universal dovetailer, not Hal Finney's UD which is typical ASSA use of an *Universal Distribution* (closer two the second paper of Schmidhuber based on computable probability distribution than to anything related to the 1-3 distinction). What QM do very well is to explain notion of 1-person plural from 1-person through the division of subject (à-la Washington/Moscow) into division of population of subjects (by contagion of superpositions), by entangling the quantum histories. QM can do that thanks to its double linearity (linearity of the tensor product, and linearity of evolution). A priori comp should completely failed on that, but then what I have done is showing that the nuance brought by the incompleteness phenomenon, gives much room to doubt that comp is already refuted. But then again, we have to extract the double linearity from comp without postulating QM, if we want keep comp, or even just QM (without collapse).
