This is an interesting discussion of YT Kids and the role of algorithms. This is an issue that came to light through James Bridle’s post last year.
I must admit that I still use the YT Kids app sometimes. For example, the other day my daughter wanted to watch a song from Little Mermaid. I used the app and it was interesting what I found:

It made me think about how that result may have been produced. I listened to the song. It was fine. It was basically a song inspired by The Little Mermaid. I just wonder why horror was allowed through.
