My metaphysical intuition finds it rather unlikely that string theory would be important for volition extrapolation: in an ensemble universe of hierarchal ontology, computation-specific physical laws are not as important as resolving confusion about things like self-representation and determining languages/prefixes for UTMs: problems that I and more importantly folk at the Singularity Institute are working on (and problems that people from the decision theory workshop sorta flirt with now and then).

Flesch-Kincaid grade 37. Congratulations, I don't think many people regularly pull that off without deliberate intent.
