Yep; it is explicitly is talking about either active devices or literally cases where the topic of focus is control/behaviour of electrons.
> If you are physicist you might envision electronics as control of emission of electrons. If you are an actual engineer you will have very different definition and understanding of what electronics is.
It has nothing to do with the level of abstraction at which you're working, which is my entire point; whilst an engineer may very well not be considering the behaviour of electrons in day to day work, if she is doing electronics, she is working with devices/technologies which involve the control/emission of electrons. If she is working on, for example, an induction machine, she is not doing electronics.
Again, I'm not contesting that people work at different levels of abstraction within a field, just pointing out that the term "electronics" as opposed to "study of electricity" has absolutely nothing to do with abstraction; it refers specifically to whether <active devices/transistors/semiconductors/control and behaviour of electrons/whatever you want to call it> is involved.
