If so then obviously "the quantum level" is not the end of the story.

They have nothing to fear from me or the truth. If retro-causality exists then things
are not local and not realistic either, so that possibility has not been ruled out
experimentally.
"Retro-causality" is always present in a deterministic system because boundary conditions
can be in the future instead of the past. Newtonian mechanics included "retro-causality"
and was still realistic (in the sense of only one definite result). MWI is the same,
deterministic and one definite result - except the definite result includes
non-communicating "worlds" including the observers. Maybe it should be called the "hidden
worlds theory".

But the common sense view that most people, including Einstein, had about reality, that
things are realistic and local, CAN be ruled out. And of all the people on the planet
John Bell would be the last to disagree that if his inequality is violated then things
are not local or not realistic or not either.
