Einstein's Worries and Actual Physics: Beyond Pilot Waves

Tim Maudlin has argued that the standard formulation of quantum mechanics fails to provide a clear ontology and dynamics and that the de Broglie--Bohm pilot-wave theory offers a better completion of the formalism, more in line with Einstein's concerns. I suggest that while Bohmian mechanics improves on textbook quantum theory, it does not go far enough. In particular, it relies on the "quantum equilibrium hypothesis" and accepts explicit nonlocality as fundamental. A deeper completion is available in stochastic mechanics, where the wavefunction and the Born rule emerge from an underlying diffusion process, and in a contextual, category-theoretic semantics in which measurement and EPR--Bell correlations are reinterpreted as features of contextual truth rather than of mysterious dynamics. In this framework, the measurement problem and "spooky action-at-a-distance" are dissolved rather than solved. Finally, a dynamics based on Rosen's "classical Schrödinger equation" provides a continuous passage between quantum and classical regimes, eliminating any sharp Heisenberg cut.
