The actual forces promote toxic platforms like TikTok, Sora, Twitter, BlueSky with no real productive value at all. Even HN is a waste of our lives yet here we are.
I have a great time on the internet. I meet new people all the time, and I have met many of them in real life, and many of them have become good friends. I am sorry you're having such a bad time, but if you looked around, you'd see there are many healthy communities built around all sorts of interests.
Some of them even live on TikTok. I don't use TikTok, but my girlfriend uses it quite a lot and while there is plenty of brainrot, she also learns a lot from it, too.
