I know you’re joking and that there’s a lot of garbage videos out there, but what possible value would there be in sending a novel per second? Can anyone read a novel per second? It only makes sense to use the higher bandwidth to send higher density information like video, audio, or interactive media like games.
I have watched many a video that showed how to do a mechanical thing visually in a way that wasn’t clear in text and still images. A backyard mechanic describing how tonget some rusty piece unstuck while doing it at the same time is so informative in a way that text and pictures cannot replicate.
