True.

Also true....but then… why would you say "/I, too, would expect to
see interference bands/" if Deutsch's experiment was actually
performed?
Because no which-way measurement is actually made in the Deutsch set-up.

I stopped reading Hossenfelder sometime ago when she started
defending Superdeterminism; yes it can explain all the weirdness
in the quantum world but it requires, quite literally, the
greatest violation of Occam's razor that is possible in order to
do so. I would even go so far as to say Superdeterminism requires
an *INFINITE *violation of Occam's razor, and that is not a word I
use very often. For that reason I don't see how any rational
person could take Superdeterminism seriously.
Yet you happily swallow a theory which postulates that EVERYTHING
nomologically possible happens?

Belief in superdeterminism, or Zoroastrianism, or whatever, does not
mean that everything a person writes is nonsense. To believe so is an
example of the very worst form of argumentum ad hominem (or feminem in
Hossenfelder's case).
Besides, Sean Carroll gives essentially the same explanation from a
many-worlds perspective:
