I have been trying to get this point across for ages; I really hope Jim has more success. Quote Tweet Jim Baggott @JimBaggott No, the Copenhagen interpretation does not entail the collapse of the wavefunction.Then, if I look at a spin in the 1/sqrt(2) (up + down), with a {up, down} measuring device, I am myself in a superposition state, if the wave does not collapse. Non collapse entails many world, or better many dreams. In that case there is no collapse, but also no waves needed, as it has to be explained by 2+2=4 & Co. Bruno The best comment by a physicists (Associate Professor, Monash University) in the discussion thread: The wavefunction is not a physical thing - so whether it collapses is irrelevant. At least one physicist not brainwashed into the current religion.Baggott and also Hosenfelder seem to be endorsing an epistemic interpretation like QBism, but they don't directly discuss the problems with it. Brent Can you list some of these problems? AG
It makes the wave-function a description of personal knowledge of the system according to the PBR theorem https://arxiv.org/abs/1111.3328
