Computers in particular, while not special, are good examples because they

I would rather choose a speculative interpretation that turns out to be
wrong then say QM needs no interpretation, nor should we look for one, as
the paper you recently cited suggested.

If Fuchs et al operated according to this quote, they would see that a
model is not the same thing as the description/predictions of observed
phenomena that it makes.
If we identify reality only with observed phenomena, what is to prevent us
from falling into solipsism or idealism?
