They keep needing to adjust their interpretations based on new results, and I haven’t yet seen a compelling adjustment that explains the results of A strong no-go theorem on the Wigner’s friend paradox (2020). That conflicting measurements of a superposition can be made seems to go against the inherent realism of pilot wave theories.
There have been a few attempts to address the classical Wigner setup from a Bohemian point of view, but the experiment above was more “a two layered Bell” than Wigner’s friend despite being inspired by the latter.
It actually looks like there’s already just a paper from two weeks ago (Li, Wigner’s friend scenario and a new interpretation
of quantum mechanics (2023)) attempting to rework the pilot wave theory into a new interpretation predicted on a different interpretation of Born’s rule to square it with the no go experiments.
So while I agree that it’s too early to call realist interpretations misunderstandings, I suspect the writing is on the wall and over time we’re going to see them drop off more and more, especially if the recent trend in experimental results throwing objective measurements into question continues.
Eh, maybe.
