Great article. Bohmian mechanics is often dismissed with reference to the impossibility of hidden variables due to Bell. So I enjoyed reading the following bit:
> Here’s how Bell himself reacted to Bohm’s discovery:
But in 1952 I saw the impossible done. It was in papers by David Bohm. Bohm showed explicitly how parameters could indeed be introduced, into nonrelativistic wave mechanics, with the help of which the indeterministic description could be transformed into a deterministic one. More importantly, in my opinion, the subjectivity of the orthodox version, the necessary reference to the “observer”, could be eliminated. …

The way I've always understood it is that Bell's theorem eliminates theories with local hidden variables, but Bohmian mechanics has explicitly non-local hidden variables.
