This article strikes at a very salient set of points about smartphones and social media. As someone that specifically tries to only use federated social media because it avoids some of these dark patterns, I certainly agree with. I also use my smartphone without any notifications turned on, ever.
Unfortunately the author has a few paragraphs that miss the mark and strike me as coming from more of a centrist or right-wing "kids these days are too soft" which feels very off-base and disconnected from the issue. For example:
This is why life on college campuses changed so suddenly when Gen Z arrived, beginning around 2014. Students began requesting “safe spaces” and trigger warnings. They were highly sensitive to “microaggressions” and sometimes claimed that words were “violence.”
The scare quotes around microagressions, a genuine issue faced my marginalized communities, is really uncomfortable and gives an unfortunate perspective on some of where this author is coming from.
Putting that aside, I really do feel like most of what is said here is on point. Reducing social media use is imperative. Designing smartphone UX that doesn't shove notifications at you would also be a good idea. Getting younger people involved in communities and forming friendships is incredibly important.
Hey, don't just blame the parents. In the back half of this article the author points out that social media harms youth no matter if their parents let them use it or not because of the social webs it creates. If you choose to keep your child off social media then they could just as easily end up isolated from their peers because everyone else IS using it.
