I believe, at its best, it’s an incomplete model suitable for low-level understanding (which may be enough for most people). But it leaves out important aspects like magnetic field work and probably a host of aspects from quantum theory.

Ok, yeah, I'll agree with incomplete. Only useful for considering the bulk flow of electrons assuming no bulk EM field.

Thanks for the read.
