I think 100 years from now, we're going to look back at Social Media like we currently look back on child labor and cigarettes. "Why on earth didn't we regulate it earlier?" All the signs are there that this stuff is terrible, but we plug our ears and pretend people are rational and will do what's good for them, and insist on treating corporations with kid gloves because stock market must go up. HN has a thick, libertarian "everything government does is bad" streak running through it and we sit at a position of great privilege--the privilege of being well-off techies, having agency over our lives and the ability and choice to avoid things that are bad for us. So you're not going to get much sympathy from this crowd.
