shut-up-and-calculate

The contemporary ‘shut-up-and-calculate’ interpretation of quantum mechanics (as the physicist David Mermin called it) denies that physics is in the business of describing a real world, in order to avoid any literal commitment to Schrödinger’s ‘magic’.
...
The [Bell] theorem turns on Einstein’s own discovery that many phenomena in the quantum world show a kind of ‘discreteness’ not present in classical physics.
...
But he didn’t see the difference between the two proposals, apparently, and threw out the retrocausal baby with the superdeterminist bathwater.

retrocausality... hmm... why would anybody prefer it over superdeterminism? or over action-at-a-distance for that matter.
We now have two reasons for taking retrocausality seriously. First, it offers an elegant explanation of the Bell correlations...
как в анекдоте: во-первых, это красиво.
