I'll give my opinion though. It's not that social media apps are the ones hurting us, they are merely exposing us to the nasty nature of humans. Closing your eyes and not using social media doesn't mean the flow of likes and comments will stop. And likewise shutting down social media doesn't mean we will forget what we had before. The cat is out of the bag, humans will now chase to be the top 1% at everything, money, attractiveness, power, etc. Even without their phones they still have permanently changed their worldview.
I don't see a solution other than perhaps shut down the internet completely. And invest in better mental health coping strategies
