It would help if these weren't all from the same single source: Zeilinger's Vienna group and friends.

On the other hand formalism works seamlessly mathematically, which cannot be said of standard quantum mechanics. Even this year's Fields medalist Figalli has a paper on how good things are in Bohmian land.

Fine, here's another from Ronald Hensen at Delft:

Experimental loophole-free violation of a Bell inequality using entangled electron spins separated by 1.3 km 2015 https://arxiv.org/abs/1508.05949v1

"...This result rules out large classes of local realist theories, and paves the way for implementing device-independent quantum-secure communication and randomness certification. "

[akvadrako]

This isn't relevant because Bohm's theory isn't local. There are much stronger results like PBR ruling out a large class of non-local realist theories, but that also doesn't include pilot wave theory.

No known experiment can rule it out because it's predictions equal those of Copenhagen.

[thraway180306]

This is something different. Zeilinger paints himself disproving realism alone and has a well known philosophical stance/bias here. Local realism testing here however is about being both local and realist, and pilot waves aren't local to begin with.

[jmcmichael]

Yeah, that makes sense. Do you have an example of Zeilinger's writing where he discusses his philosophical stance?

Is a philosophical stance something you believe that a physicist shouldn't have?

[millstone]

Isn't special relativity a serious mathematical problem for Bohmian mechanics?

[thraway180306]

Relativistic extensions aren't pleasant in standard QM either.

Bohmian formalism would require something perhaps no less aesthetically repulsive, but surely more alien: a preferred foliation of spacetime to avoid a preferred reference frame. Turns out it wouldn't have to be an artificial choice, as it can be derived from the wave function itself https://arxiv.org/abs/1307.1714 (that would also mean this preference existing within QM irrespective of any interpretation).
