Good point. Reading this article, it also crossed my mind that the level of detail is always arbitrary. There is no "right" level of detail, that explains everything. We can keep going infinitely more into detail, explaining each step in more and more detail.
This article could just as well have included an explanation of how and why electrons travel from one point to another, or "the quantum effects that govern this" (a figurative example).
A metaphor for this that references the world of electronics is the ability to always increase the resolution of a display. We can keep going on, although the human eye might not be able to pick up a difference after a certain point.
Perhaps there is also a limit to the usefulness of increasing the level of detail in an explanation, as this article does, just as there's a limit to the usefulness of increasing display resolution.
