Heartily agreed! While _some_ things benefit from video (like "How do you take apart this thing?", though well made photos do the same), most things really don't need a video and bad voice over.
FWIW, there is this script:

which converts YT videos to a series of screenshots along with the subtitled text. I have not tried it, so I don't know how well it works.
