It is just that video content generate so much more monetization. At least compared to work done. Thus most relevant content is generated as video instead of text. And those generating text are struggling with revenue sources.
If you're a new creator and don't have family with good media connections, then YouTube is pretty much the only way that you can actually get paid for what you make. Regardless of medium.
Anybody tell me what are the other realistic options?
Maybe not books. But let's ask would they prefer video to check ingredients in a recipe or a textual article? Or maybe video instead of wikipedia page to verify some facts...
Similar things go to many things that would clearly be superior as text, but there simply isn't that much money in something user will quickly skim over. Instead of forced pre-roll adds and sponsorships.
