@Daojoan You are onto the truth. I love the convenience and art of video/film. However, "educational film and tv" are time consuming and frequently/usually unclear. While I use maps for navigation instead of a list of directions, I much prefer a guide with good clear drawings to a video tutorial. The latter are to keep viewers online while data harvesting. It's the tyranny of the filmmaker to control how viewers are fed information. As kids, we mocked "educational films" as time out.
