Contrary to the article, there is no doubt: Socrates would have no use for social media. His view is closer to Freud's, who remarked in a letter to Lou Andreas-Salomé : "In the depths of my heart I can’t help being convinced that my dear fellow men, with a few exceptions, are worthless." & Elsewhere "In my experience most of them are trash, no matter whether they publicly subscribe to this or that ethical doctrine or none at all ... If we are to talk of ethics, I subscribe to a high ideal from which most of the human beings I have come across depart most lamentably." - this is much the tone of Plato.
