Late modernity is characterized by the emergence of a massified, technocratic society dominated by Artificial Intelligence (AI) algorithms—factors that foster the reification and dissolution of the singular person [1]. Faced with this scenario of systemic depersonalization, this essay analyzes the challenge posed to contemporary philosophy to recover the concept of the ethical and relational subject [1-6]. Integrating the foundations of French personalism by Emmanuel Mounier and Maurice Nédoncelle, the philosophy of dialogue by Martin Buber and Emmanuel Lévinas, and confronting them with the implications of cybernetics and transhumanism, it is argued that human dignity and the ethical consideration of vulnerable subjects can only be safeguarded through a rediscovery of alterity and ontological attention [1-9]. It is concluded that technological advancement must be subjected to a humanist filter, preventing technology from reducing human beings and living entities to mere manipulable data [1].
