  We formulate Bohmian mechanics (BM) such that the main objects of concern are
macroscopic phenomena, while microscopic particle trajectories only play an
auxiliary role. Such a formulation makes it easy to understand why BM always
makes the same measurable predictions as standard quantum mechanics (QM),
irrespectively of the details of microscopic trajectories. Relativistic quantum
field theory (QFT) is interpreted as an effective long-distance theory that at
smaller distances must be replaced by some more fundamental theory. Analogy
with condensed-matter physics suggests that this more fundamental theory could
have a form of non-relativistic QM, offering a simple generic resolution of an
apparent conflict between BM and relativistic QFT.
