​True. ​



Nice we all agree!

Note that one world is as much an hypothetical construct.

No, you can kick it and it kicks back.

That illustrates the existence of a physical reality, but that cannot count as an argument for its uniqueness, nor for its primitive or prior fundamental existence. On the contrary, QM and computationalism can both be used to argue of the consistency of either the 0 physical universes hypothesis (there would be only a first person sharable "video game") or for the many worlds hypothesis (like Everett, Dewitt, ...).

But the point is that there's ONE universe you can kick and feel it kick back. That ONE is less a hypothetical construct than all those others in MWI and eternal inflation.

That depends on the interpretation. Deustch would argue that today and tomorrow are already parallel universe in the quantized space-time, and if the theory is simpler with the many relative views, why not taking it seriously. Then in my dreams, I can also got the strong feeling that reality kicks back. It is the type of things that universal number do: making a person into believing. In video game like second-life, reality seems also to kick back, where of course the normal gamer don't forget completely the reality he started the game in, but even without the formal confirmation, the fact that arithmetic contains all universal games, makes me think that asserting the primariness of the physical reality might be ... premature. Especially when that materialist tradition is based on using authoritative arguments on the mind-body problem, or eliminating the person.
