The whole vibe is so wholesome that it's truly the first social network that feels social in a wide sense.
On top of that it is designed to be addicting for the sake of addiction. It doesnt matter what the video is about once it will keep the user on the app. The algorithm will work out the perfect way for each person to be sucked in. We all know that these addicting videos won't be educational or even worthwhile. This type of stuff trends towards really useless content.
Of all the social media out there I would not let my kids use tiktok.
But maybe tiktok is better in this regard, heard much praise about their algorithm.
