I want to ask this in the Relativity forum but thought there are more quantum experts here. So most of you Bhobba, Neumeier, etc believe the world is really classical and all the quantum things are just for calculation purposes or aids. Can you take the analogy to General Relativity? Can we say that in GR, the world is still classical and the Einstein Equations are just for calculation purposes? But then matter really gravitate.. so it's not just classical thing? And if this is true and GR is anti-classical.. then it's not at all a stretch that QM is also not just about calculations or measurement theory in classical world? It would give stronger basis if GR is also like QM that matter really gravitate and is it not a clue?
