Part of what makes YouTube’s recommendation algorithm so powerful is that it doesn’t necessarily have to be very good. I scrolled through my recommendations just now and only found one video after scrolling through fifteen that I was interested in watching — but that’s fine, since it’s easy to decide if you might like a video based on its title, thumbnail, and creator.
However, if YouTube was as good at recommending books as it was recommending videos, I would never use its book recommendation algorithm. You necessarily have to get almost every book recommendation “correct” for it to be seen as actually useful by the user.
