Another issue, is that publicity and interconnectedness of all discourses we have nowadays, increases a homogenuity of thinking patterns, in other words it hurts the diversity of the ways of thinking, that is also something that can be improved by more people going private and having closed interest groups in chats invisible to public web.
Where is your evidence of this?
It is a mistake to think pushing everybody to talk only in private will increase the diversity and quality of discourse. It will NOT, it will collapse conversations into simpler more reductive narratives.
What? Do you not listen to music? Or enjoy art? Do you not watch theater or tv? Do you not enjoy going to local craft shows and seeing local artists? No matter what happens in the 2000s, the 1900s will be remembered as one of the most artistically prolific, free and diverse periods of human expression and art. Yeah there is censorship, yes western culture is very conservative in ways it doesn’t want to admit sometimes, but in general the shear volume and variety of art created in the 1900s is immense.
