AI must be “disarmed” in order to free it from the mentality of military, economic, and cognitive competition. “To disarm means discrediting the assumption that technical power automatically confers the right to govern,” he says. “To disarm does not mean rejecting technology, but preventing it from dominating humanity” (110). He devotes ample space to a critique of transhumanism and posthumanism, which interpret progress as the overcoming of human limits. Instead, limitations are not defects to be eliminated, but a constitutive dimension of the human person, because it is in fragility and finitude that relationship and openness to God and to others mature. He says we must remember that “humanity flourishes not despite limitations, but often through them” (118).

Pursuing technological innovation at the expense of eliminating human limitations, he says, would cause an anthropological regression. “Humanity—in all its grandeur and woundedness—must never be replaced or surpassed,” he says. Technology can alleviate humanity’s sufferings and open new possibilities, but it must not deny the essence of humanity, which is our “capacity for relationship and love” (126). In the face of AI, says the Pope, “the true alternative is not between enthusiasm and fear, but between two paths of development: a progress that serves individuals and peoples, or a progress that subjects them to the mentality of power” (129).
