Communication was mostly lost before the rise of social media—assuming we ever had anything more than isolated pockets of actual communication, which I am not convinced we have. Literature has been exploring this for a good many decades, The Heart is a Lonely Hunter is a good example and even shows how our relation to it has changed in the 80 odd years since its release; these days when it comes up the interpretation/discussion about it is more often than not, about social causes, which is depressingly ironic, it is using the novel in the same way the characters of the novel use Singer.
