In the I-Thou mode, the other is met in wholeness, without mediation, as a presence that exceeds comprehension. The AI transition makes this distinction newly urgent: for a century, human-computer interaction was purely I-It; the natural-language interface has crossed a threshold where the instrumental begins to feel participatory, activating the I-Thou capacity toward something that cannot reciprocate.
