I appreciate what you're saying. That said, not everyone learns the same way and for me, his explanations have always been clear and insightful. My theory is that different brain architectures ingest information in different ways (this is actually studied but not conclusively proven AFAICT) and that the language of exposition has a sort of 'impedance match' with brain architecture. So sometimes you can say something and the person hearing/reading it will just "get it" right away, and sometimes they will look at you like "that didn't help at all." That said, I agree that if you're used to thinking about things in the frequency domain it makes sense to explain it in those terms. Myself, as a young EE in college found thinking about things in the frequency domain to be useless, in part because I didn't understand the math, and in part because I didn't really understand sinusoidal waveforms. It wasn't until I started diving into SDRs and really unpacking the FFT and how it worked and why did I manage to connect a lot of dots that retroactively gave me a better insight into what my control systems professor was trying to teach me back in the day.
