(I had to go double check my recollections on this!) It's not at all a new process. DeBroglie proposed it as early as 1925, but abandoned it, ironically enough, precisely because Bohr pointed out to him that it's non-local.
Correct me if I'm missing something, but the fundamental difference between Bohm's (pilot wave) and Bohr's (standard) interpretation is Bohm's claims that a particle exists between the time it's created and the time it's observed and Bohr's claims that it doesn't. Which one strikes you as requiring more black magic?
I think that's a mischaracterization of the Copenhagen Interpretation. It would be more correct to say that (according to the CI) a particle's properties don't exist before they're measured.
Which one strikes you as requiring more black magic?
Neither. The nonlocality itself is the black magic, in my mind. There's a retroactivity about it, if you will, and that's what leads to all the counterintuitive shenanigans of objects at the quantum scale.
