is that it’s a video (and that long) when the information could have been more succintly and practically displayed in a text tutorial or a blog format. Basically “this could have been an e-mail”.

Or it's a lot of information to digest and an "e-mail" or blog article would have been too long and visually-unappealing to properly convey the information. Videos have words, pictures, and sounds. Even if it was in article form, they just want it so that they can skim parts of it, and pretend to read it, while not digesting a damn thing. Why bother with actually reading anything when you can shove it in an AI summarizer and get the best possible summary that takes 5 seconds to read?

Not to mention that way people avoid having to go to YT which is yet another cesspit community-wise.

It entirely depends on the channels you watch. All of the comments I read on the channels I follow are fine. I don't know what other people are having a problem with, but maybe they shouldn't be following Mr. Beast or Logan Paul bullshit.
