I suppose it boils down to why the Feynman lectures are generally considered a gold standard in technical presentations.
His explanations focus on the most important bits (which he has skillfully prioritized based on his expert knowledge) and avoid highly domain specific nomenclature i.e. he gives a thorough-yet-concise explanation in a way that a reasonably intelligent lay person can understand.
Agreed. This is also why I adore the SICP lectures from the 1980s [1] (and the book in general).
It broke programming down to its most fundamental and important building blocks without all the baggage of machine/operating system/application/dependency/etc specific stuff.
His explanations focus on the most important bits (which he has skillfully prioritized based on his expert knowledge) and avoid highly domain specific nomenclature i.e. he gives a thorough-yet-concise explanation in a way that a reasonably intelligent lay person can understand.
Does that make sense?
