Not being on Tiktok is not social isolation nor is it mentally devastating. I think many here are projecting their own addictions when they make these hyperbolic assertions.
And conversely without understanding the isolations modern children experience that your counterassertions fall short explaining the current situation we're in.
If your solution is "go play outside with other kids" and the park is empty because all other kids are busy doing isolated things or on tic tok, then you have a problem.
