I think you may be onto something.....a friend showed me some TikTok videos from China the kids watch there..mostly socially responsible things... Its all about the algorithms and censorship ...our kids get the bad results 1st ..... Not so in China...Don't know that its true...but it did make me think...
Children in China are limited to 40 minutes a day on TikTok. It is shut off at 10 PM. TikTok videos in China are educational, with topics like home science experiments and patriotic videos.
Chinese kids are not watching the waste-of-time stuff that the kids in the USA watch and sometimes even get addicted to. TikTok uses AI to detemine by their clicks what people outside of China like and then send them a stream of videos that they would like. This keeps some kids watching for hours on end. Of course TikTok can slip in some very harmful stuff as well as the junk.
