Boggles my mind how. Unless it is an arts and crafts or mechanical or some other hands on video, it is so inefficient to watch someone talk rather than just read the transcript.
It's well known that not everyone does best with text. It's why most college lectures have a text/notes, a lecture, and a discussion component. Some value the interactivity of the discussion, some the audio of the lecture, and others the text itself. For the longest time the internet mostly gave value to people who preferred to interact in text. Now the internet is wide open to give value to people who prefer interacting in discussion, video, audio, and more.
I do. My time is valuable. And text is also much easier to archive for future reference.
It's also much easier to skip through parts in a written document because you can see the context before and after easily on a written text. Whereas with video you have this kind of catch up every time you skip.
It’s not the only difference. If I think along with a video/audio, I lose tracks quickly and have to rewind, but there is no obvious cue to where. Text has a fundamental property of being in sync with whatever level of attention I’m paying to its parts. Talk doesn’t have it.
TikTok and IG are mostly for entertainment not for learning, not sure how efficiency apply. Also we are talking about an instant stream of short clips, not old school YT where launching a video requires clicking and waiting.
