Will also note that the views of the author and their partners are pretty damn conservative having released a book entitled "The Coddling of the American Mind". The jist of the book is that american kids are too soft and too prone to victimhood, rather than having legitimate grievances about the capitalistic/individualistic social and emotional systems that exist. To me this completely ignores almost all of the positive advancements the younger generations have done especially in terms of stopping generational cycles of emotional, physical and sexual abuse - the current generation is the least abused generation in the history of the US.
Its with that lens that I view the opinion piece and still agree on some level that social media is harmful.
