I'm not sure I agree with this. Our societies globally have become hugely polarised and are manipulated daily because of social media. The damage done by social media is 100x greater than any good that came from it and the lives of adults have been affected by on it a societal level at least as much as the danger to kids.
It isn't possible, but if social media was suddenly completely unavailable I think the world would get a lot better in a very short period of time.
