"But pilot wave theory could still be important, because it has a different conceptual formulation, so if you set out to modify the theory, you get different modifications. In that sense, it is a good new idea. I personally think that you can produce a truncation of pilot-wave which doesn't coincide with ordinary quantum mechanics, but which is mostly the same as quantum mechanics when you are dealing with only a few particles only slightly entangled. In this case, you need the wavefunction to be a complicated function of the hidden-variables (the particle positions) which only obeys the Schrodinger equation approximately. This type of thing is a true modification of quantum mechanics, but I was never 100% sure that it works. I described the idea roughly in my answer to one of 'tHoofts questions on physics stackexchange."

Also, determinism will be resurrected. Look at Pilot Wave theory. It explains quantum weirdness with a deterministic worldview, but everyone would prefer to hype voodoo theories.
