That might be obvious, but when a significant number of people don't pay enough attention to know something is AI, or simply watch it anyway and then scroll onto the next clip, so it keeps them engaged rather than bouncing them off the platform, it's still doing it's job of retaining attention to push more ads.

Most people I know will claim to not like AI, but they happily continue to scroll their Facebook, Instagram, or TikTok feed that's full of it. Until they delete the app in protest and go read a book, little will change.
