The problem of SW theories is that they had to postulate measurement as
special kind of random event, which seemed at first to be defined only
in relation to the mind of the measurer. So it got tangled up with the
mind-body problem. This was largely relieved by decoherence theory
which explained measurement as a purely physical process. If
decoherence theory had been better developed before Everett, MWI might
never have become an attractive interpretation. MWI got rid of the
special random event by postulating that all results happened, just to
different copies of the experimenter or intstrument. But it still left
a gap as to what physically constituted the branching process and how
did this process result in the Born rule.

*Victor Stenger* said this from the time I first connected with him
over 20 years ago.
It is rare to find any physicist in popular media that believes this.
*Sabine Hossenfelder* doesn't believe this.
