Quite interesting talk. I don’t see, nor does she, select one history, but that is not troubling for a digital mechanist, as if they found the measure, it has to be a first person one, and that justifies the apparent unicity of our personal experience. She could have cited Omnes and Griffith consist histoires, but it is the right direction. It gives me the feeling that the remand of non locality in the MW might be due to the use of Hamiltonian, instead of Lagrangian. Nice to see that GHZ implies no classical histories at all. One mind. Many dreams.
