As near as I can tell, physicists worth their salt look at the math of QI and literally see flying saucers because QI asserts that gravitational mass is not equal to inertal mass.
This is weird, as the equality of both masses is not a fact. There are many experiments trying to proof both masses are inequal. For now, they only have managed to demonstrate that the inequalities should lie at the 14th digit level, if any (see here for instance).
I believe the only thing pilot-wave doesn’t explain very well is quantum teleportation.
The pilot-wave interpretation relies on a non-vanishing potential at infinity. This consists in a very non-intuitive thing.
Somehow, it does not like the non-locality behind quantum mechanics, and get rid of it in a way closer to classical mechanics at the price of a potential,... that is non local. Therefore, all the non-intuitive aspects of quantum mechanics are still there. At the end, only data will tell us on which one (the quantum mechanics or pilot wave interpretation) is correct. For now, both agree and there is no way to disentangle them. If interested, I may try to free some time to write a full post about that (I discuss this topic in my book, but it is in French :p )
Thus, its funny. There are two things Einstein said, mass equivalencies (against QI) and spooky action at a distance (for pilot-waves), that are both in play.
The EPR paradox has been solved since them (cf. Bell inequalities) and there is no spooky action at distance (this is proved and well established). This contrasts with pilot wave interpretation that is neither proven correct or wrong.
