I wonder if that's part of the reason for their algorithms to push the same videos to everyone, they're already cached at the edge so it costs them nothing?
More popular works are more likely to be enjoyable to more people. There is no really objective measure of quality for any creative work, and taste doesn't scale, so publishers bias for popularity as it's one of the few things they can understand.
The majority will enjoy and like whatever is pushed on them. Decades of radio and TV should be enough evidence for this. Music or video is not popular because people like it, but because somebody decided to make it popular by pushing it on people.
