Unless and until it has a human pre-moderating all videos, I ain't trusting it and will be treating it just like YouTube. I.e. it ain't for kids and mine's going nowhere near it.
Magic algorithms still can't do what one human being can. The fact they won't use a real person for vetting children's videos is symptomatic of everything that's wrong with Silicon Valley culture.
I bet employees who do have children won't let them anywhere near it.
