"The “collapse of the wavefunction” was never part of the
Copenhagen interpretation because the wavefunction isn’t
interpreted realistically." I have been trying to get this point
across for ages; I really hope Jim has more success.

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.

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.
