This article suggests that machine learning and collaborative filtering are incapable of producing healthy recommendations. I beg to differ, the New York Times may not like the result but they work for the vast majority of users on any service with too much content to manually curate.
Yes, but you _must_ understand that most (no, ALL) of the millennial generation grew up with public content over the airwaves that was curated and had to pass certain guidelines. So many parents think that the YouTube Kids app is the same thing. it's not!
If YouTube want to be the next Television, they're going to have to assume the responsibilities and expectations surrounding the appliances they intend to replace. Pulling a Pontius Pilate and tossing the issue to another algorithm to fail at figuring out is not going to fix the problem.
Thankfully, there's much more out there than YouTube when it comes to children's entertainment, actually curated by human beings with eyeballs and brains, and not algorithms. The problem is that parents don't know these apps even exist, because YouTube has that much of a foothold as "place to see things that shut my kid up, so I can see straight."
