(I didn't downvote you)

Surely "tutorial videos" are only a tiny fraction of YouTube videos? And also, some tutorial videos cannot be replaced by a textual (or even graphical) LLM description, especially if the topic being described is visual in nature and it helps to see the other person doing it.

Yeah, I'd think if an LLM's instructions are sufficient, one would have used a written tutorial in the past and not watched a video.
