Why is Bell’s theorem still considered controversial?

[danieltanfh95]

Which would be?

BM is one example but more generally, I’m referring to parts of the Quantum Information community engaging with Bell foundations through hidden-variable framings or finite-speed-causation puzzles (not the operational / device-independent folk, which is fine), and by extension some of the Holography programme (ER=EPR treats entanglement as geometrically classical wormhole connections) and parts of the entropy / thermodynamic-gravity line.

And for example the newest shiniest thing which is in a similar tradition: https://perimeterinstitute.ca/resea...d-initiatives/celestial-holography-initiative
