As someone that grew up with social media and the internet from the moment I could read, I struggle to understand how social connections worked before it. Broadband become mainstream in just the last ~20 years. Social media that quantifies someone's popularity absolutely affects teenagers' mental health. But social media also means support groups on reddit and places like HN.
The surgeon general wants to explore and understand the way different social media affects mental health. But the way this issue is presented by NYT, and in general, categorizes all social media as the same. This framing is going to make younger generations ignore these "warnings" as out of touch, because it is. Similar to how my parents call every game console or video game, "playing the Nintendo". These overgeneralized discussions make most people dig in to their already held beliefs. This also gives overbearing parents fuel to invade the privacy of their children, which harms children's mental health, and leads to trust issues, more than social media ever will.
