I'm curious if the question posed my Smolin
Could quantum mechanics be an approximation to another theory?
"We consider the hypothesis that quantum mechanics is an approximation to another, cosmological theory, accurate only for the description of subsystems of the universe. Quantum theory is then to be derived from the cosmological theory by averaging over variables which are not internal to the subsystem, which may be considered non-local hidden variables. We find conditions for arriving at quantum mechanics through such a procedure. The key lesson is that the effect of the coupling to the external degrees of freedom introduces noise into the evolution of the system degrees of freedom, while preserving a notion of averaged conserved energy and time reversal invariance..."

Has been reflected/discussed here in some past thread? I'm curious to here how others reflect on this?
First, how do you reflect over the relevance of the first overall question? and second, how do you reflect over the suggested reasoning
"Quantum theory is then to be derived from the cosmological theory by averaging over variables which are not internal to the subsystem, which may be considered non-local hidden variables."
(I tried to use the search function on where with a string in quotes, but it seems to interpret it as a collection of single search words? and thus I get all kind of bogus hits? or how do you search a string?)
