I just watched a talk by Anton Zeilinger, professor of physics
at the university of Vienna, and 2022 Nobel laureate, about
quantum effects and entanglement.

 Link please? It is impossible to comment without seeing his talk.

The talk is this one: <https://www.youtube.com/watch?v=JY6UCVsiTPU>.
He had much the same talk to what looked like a class of university
students.

I'm not quite sure what he has said that annoyed JB - usually any popular science programme for a general audience dumbs down quantum mechanics to a point where it is completely unrecognisable to professional physicists.
 

What irritates me is that QM is presented as if it's a great
mystery and that no example of an experimental setup is shown,
even schematically. That denies the listeners the opportunity
to think about it for themselves. His argument using dice is
entirely empty of any useful meaning.
Some years ago, I had a closer look at a publication of his:
"Quantum imaging with undetected photons", doi:10.1038/nature13586,
in which the observed phenomenon was described as some quantum
mechanical miracle. While the experiment was certainly not easy to
conduct, what was actually going on is trivial to understand, and
in classical terms too.
The QM clique doesn't *want* to make things understandable.
