  I present a simple baby-steps reconstruction of quantum mechanics as a fully
classical theory. The most radical conceptual leap required is that there are
many coexisting classical worlds, but even this is justified by the necessity
of objective probabilities. These baby steps lead to a version of the
many-worlds interpretation of quantum mechanics with built-in probabilities,
built-in classicality at the macroscopic level, and an explanation of the
complex numbers in quantum mechanics. Despite its simplicity and minimalism of
radical concepts, this is not a toy model, being equivalent with quantum field
theory.
