I can't disagree with an opinion like that coupled with an anecdote like that.

I disagree that it's the federal government who should be stepping in to limit screen time though.

In fact, tiktok is the only app I've seen that has a "why don't you go touch grass" timer, so in that regard, it's got less nefarious design patterns than, say, Facebook.

I don't think I understand what you mean by dangerous in this context, honestly. When I think danger, I think of bodily harm. What does your definition of dangerous entail when it comes to social media apps that physically can't cause harm? Is my understanding of danger too simplistic?
