The purpose of the tread is to provoke varied opinions and to allow those who obtain such views to offer supporting evidence. The question is this: "to what extent is QM an intrinsic physical theory?"
"Intrinsic physical theory" is not clear enough to start a productive conversation, so this thread is closed. Send me a PM proposing more clear wording and the thread can be reopened.
After some offline discussion, this thread will remain closed.
There's nothing inherently wrong with the question, but it is not one that can be productively discussed or moderated within the bounds of this forum.
