How can a reality whose subsistence is only digital and whose existence is only online have ontological consistency? Yet experience shows how the pervasiveness of communication in human life today and the new possibilities of data analysis, made possible by AI, open up real and crucial ethical questions, in the etymological sense of crux. This, in fact, is tied to a “judgement”, through the Greek term krisis from which the words “crisis” and “critical” descend. A crux represents an interpretative passage in which the attribution of meaning is difficult, if not impossible. And this concerns not only philological investigations, but also every “critical” reading of reality. These ethical challenges call into question, at the same time, metaphysics, anthropology and even theology, through the question of what reality can be recognized in virtual relations, and what epistemological criteria, consequently, are required for a conscious manipulation of big data. AI and social media to actually work and make a profit from human relationships, which are the real product at stake. But to whom does a relationship belong? Who can own symbols and language? The point of access to such questions is the symbolic, anthropological and metaphysical bearing of the relationships themselves.
