The Algorithm Does Not Love Anime
The algorithm optimizes for engagement. For watch time. For subscription retention.It does not love anime.
It does not know why Cowboy Bebop feels like jazz at 2am. It does not understand why the Chunin exam arc of Naruto made a generation of kids care about hard work and friendship. It cannot explain why FMA Brotherhood makes grown adults cry.
It knows you watched 3 episodes of Demon Slayer so it will show you more Demon Slayer.
That is not discovery. That is a loop.
