I feel we can't make laws against the subject of moral panic every generation. People have felt the same way about the activities of youths since forever. But ultimately it often turns out fine. Change can bring new problems, but it also brings positives that are hard to understand and even formulate, that's culture. Trying to be the arbiter of that is foolish.
Is ticktock addictive because of it's design, or is it addictive because it brings thousands of people and experiences and emotions right to you? Probably both, but it's hard to separate one from the other. Apps are not opium, it's not as clear cut.
Instead of micromanaging technology and culture they should make sure that society is kind, that there is slack in the system, that people don't have reason to want to flee their real lives, that those hurt by new technology get support.
Of course truly malicious dark patterns and fraud should be punished. But that feels like a different category.
