To me it shows humans simply cannot (yet?) deal with such wide-reaching communication. It's fine in neatly organised and moderated forums. But those still have some sense of privacy, similar to how people at a workplace can freely talk about things that wouldn't be fine to say on live TV.

But social media turns everything into live TV, potentially analysed with more rigor than any TV show ever witnessed, and with algorithms implicitly optimised to make the things most visible which generate the most powerful emotions. And it doesn't seem like the social media concept is going to disappear soon, it's just part of everyday life for many.
