Specific educational videos and video courses are excluded.
These works well to. That said if same material is available in text format - it would be preferred.
> I'll be surprised if more people prefer video form of content.
Not so much video as audio. I work for a company that provides digital lending services for libraries. Guess what type of content is by far the most popular? Audiobooks. It's not even close. Most of the "videoification" of blog posts I see on youtube are basically just podcasts with somebody talking into a video camera instead of a microphone.
I saw Youtube "educational" video from a low life marketing guy recorded himself speaking to camera and teaching others how to record videos of them scrolling PPT slides with affiliate links and make money out of it
Nothing irritates me more than google pimping me spammy videos as an answers on simple questions.
Videos forces you to consume information slowly in a sync manner. Videos are good for sense-rich entertainment.
Information is perfectly and efficently can be (and always were) delivered at text.
