Almost every time I am directed to a video, I ignore it and move on. That is a method of communication for entertainment. If you want to convey information, it should be in writing.
I appreciate your sentiments; however, I believe this medium was chosen for the kiddee cohort that's been voting for Obama and his rats by 2:1 or more since 2008 at least. They have been indoctrinated with anthropogenic global warming with plenty of audio-visual support.
It also helps those with less than optimum visual acuity. They can listen to the audio monologue.
I can agree with that. I'm not their target audience.
But if they want to send information to someone like me, they need an accessible transcript as well. I don't deny the medium has its uses. But for those that think it will replace written communication, I believe they are wrong.
