Right, consider the thousands of hours of online technical training content on Udemy, etc. Much of that is very clear, well-paced, and precise. Conversely, watching any number of peppy newsreels on e.g. British Pathe[1]. They're just as blaring and superficial as any contemporary correlate.

My father taught English, and had a long-standing rant about how universities since about the 80s or so produced writers that were amazingly talented at using a thousand words to say absolutely nothing.
