The paper has an interesting perspective but much of it felt wierd. I looked in my old Basic Circuits textbook and the phrase fundamental circuit element isn’t used at all. From an EE perspective, the usual basic groupings are passive and active, and linear and non-linear, because that directly relates to how to mathematically solve circuits including the components. They ignore diodes in the paper because they do not cleanly fit any of their categories. Also the frequency domain behavior/description of each component is perhaps more important.
