It's not just you. YouTube is littered with videos just like this one, with exactly the properties you describe. My guess is they are cheap to produce from stock footage, and the scripts rarely offer any deep insights but are mostly just regurgitated blurbs from Wikipedia. If narrated it's almost always by the same voice, presumably synthesized so no voice actors to pay.

I guess it's good business from the ad income sharing, and at the very least it's slightly more interesting than people posting reactions to reaction videos.
