Everett-DeWitt-Wheeler MWI and quantum electrodynamics taken together seem to basically add up to an event/process ontology with no concrete difference between subjects or objects outside the hyperflawed ideologically-individual neuronal world-simulation, only difference in relation half-assedly summed up by the idea of some high-dimensional manifold X's topological/geometric perspective(s) on itself. Maybe defeating almost all the arguments against some kind of panpsychism probably in the realm of some flavor of neutral "meta-monism" or like a monism of quantum fields, that gives a platform for the co-arising of a second order corresponding to dualism which may or may not be dual-aspect monism or whatever the kids are calling it these days. Brainstorming at work to kill time and record some thoughts....
There is a meaningful sense in which the many worlds interpretation is in fact the quantum theory with zero assumptions or conserved attributes...every other theory is in some regards Everett's math adjusted to conform to certain qualities of the "real world" that the designers of whatever theory don't wish to lose. I believe this lack of assumptions, this Occam's physics, to be isomorphic to the way panpsychism of some as yet un-formalized variant is the theory of consciousness with minimal assumptions and conservations. It answers maximum questions while treating adjusting the rules to account for certain expectations as a violation, regardless of how we feel about the necessity or lack thereof of certain components of our picture of reality.
QED=semper aliquid ex nihilo
Galen Strawson makes an interesting point in the linked article, that we must actually practice thinking process physics else we slide toward object dualism.
