In his first major encyclical, Pope Leo XIV issues a crucial warning about artificial intelligence, presenting it as a real risk to human dignity and a potential catalyst for global conflict. The document, titled Magnifica Humanitas, spans more than 40,000 words and marks a significant contribution from the Catholic Church on technology’s impact on society.
At the heart of the Pope’s message is the insistence that technology must remain subordinate to human beings. “Technology is never neutral,” he states, underscoring that it reflects the values and intentions of its creators. This assertion serves as the basis for his critique of AI, which he sees as increasingly molded by entities lacking moral accountability—namely, large corporations and influential governments.
Pope Leo specifically highlights a dangerous shift in power, where democratic institutions are losing control to major economic and technological players. This critique is particularly pointed toward Silicon Valley and the tech elite, who, according to the Pope, now possess unprecedented control over critical systems of information, warfare, and the economy. The implications of this power dynamic are troubling, especially regarding military applications of AI. The Pope warns that entrusting algorithms with lethal decisions raises serious ethical issues, emphasizing, “It is not permissible to entrust lethal or otherwise irreversible decisions to artificial systems.” This declaration vividly illustrates the Church’s commitment to human oversight in matters of life and death.
The encyclical doesn’t just stop at war; it delves into broader societal consequences. The Pope indicates that contemporary conflicts are shaped not only by traditional combat but by narratives and media, making technology and its use a salient issue in international politics. He narrates a concerning resurgence of war as a political tool, driven by geopolitical competition and rapid technological advancement. With this context, Pope Leo calls for strict international regulations on AI, insisting that nations must unite to prevent a dangerous arms race rooted in autonomous technologies. “To disarm does not mean rejecting technology,” he writes, “but preventing it from dominating humanity.” This statement reflects a measured stance that recognizes technology’s potential benefits while urging responsible oversight.
The encyclical also addresses economic ramifications. The potential for widespread job displacement due to AI automation is significant, with nearly 12 percent of jobs projected to be affected. Pope Leo frames this issue not solely as an economic concern but as a moral imperative. “The pursuit of greater profits cannot justify choices that systematically sacrifice jobs,” he asserts, reaffirming the Church’s view that the economy should serve individuals, not the other way around.
The Pope draws parallels between today’s digital challenges and historical upheavals, such as those described in Rerum Novarum during the industrial revolution. Just as previous generations grappled with the moral complexities of industrialization, so must current society confront the fast-evolving digital landscape.
Moreover, he highlights essential yet often overlooked labor behind AI innovations, such as data labeling and resource extraction, referring to these workers as part of a modern “digital underclass.” Their essential contributions, he suggests, deserve recognition and valuation in the broader fabric of society.
Pope Leo’s encyclical also addresses the troubling rise of AI-driven disinformation that threatens the foundations of democratic life. He warns, “Indifference to the truth leads… to a descent into totalitarianism.” This concern is particularly relevant for younger generations, who risk losing the ability to engage in critical thinking due to overreliance on technology. The Pope urges reforms in education to nurture reflection and moral upbringing, stressing the importance of human judgment in the age of AI.
Philosophically, the encyclical draws a stark line between the nature of humans and that of machines. As Leo points out, “So-called artificial intelligences do not undergo experiences… do not know from within what love, work, friendship or responsibility mean.” This sharp distinction defends human uniqueness and underscores the risks posed by transhumanist ideologies, which threaten to diminish the sanctity of human life. He warns that if people are viewed as mere entities to be surpassed, it becomes easier to justify the notion that some lives are less valuable.
In conclusion, Pope Leo XIV’s encyclical is a clarion call for a balanced approach to technological advancement—one anchored in ethics and responsibility. His concerns resonate beyond the boundaries of the Church, echoing the sentiments of some in the tech industry who acknowledge the misalignment of current incentives with ethical outcomes. Through ongoing dialogue with tech leaders, the Vatican aims to bridge these gaps, yet significant tensions remain.
Ultimately, the Pope’s message is cautionary, urging humanity to retain its moral compass amid swift change. The call to integrate ethical scrutiny into the narrative of progress offers a challenge as society navigates the complexities posed by artificial intelligence. As these critical discussions unfold, they compel a reevaluation of how technology aligns with human values and the essence of humanity itself.
