The aimless, constant dopamine hits are incredibly scary. Especially because people who tend towards using it are the ones who need it least. Especially in children.
I guarantee this: children who use TikTok (and YouTube to an extent, etc), will have issues in the future keeping attention on work, and other forms of important and difficult problems and introspection.
Our roommate who used it in our house is a dopamine addict. He never reads, is by far the laziest and sloppiest, he’s also unapologetic about it and unwilling to acknowledge it, sucks at conversation generally because he has nothing to add because all he does is game, YouTube, TikTok and work, and they all feed into each other. And worst - he’s just totally comfortable being the laggard. Everyone else is happier. They contribute more. They clean, they maintain. They do more and have more to talk about because of that.
I fear a generation of children raised on constant dopamine drip. I already see how hard it’s become for me to sit and read or sit and meditate and I try and avoid all that (Twitter is my vice). But I have a friend with a daughter who is addicted to YouTube/TikTok and I fear greatly for a generation raised like that.
