Here's another perspective: are there socially well-adjusted adults who get sucked into it and ruin their lives? We're inclined to care about the kids most, but kids are resilient and continue to grow and adjust and change over the years. What about their parents? Are there adults who get sucked into social media addiction and it ruins their lives? If yes, how common would you say it is?
(I'm not trying to lead an answer here. I thought about it for a couple minutes and I haven't decided for myself.)
