Leo in new AI text condemns ‘culture of power’ that fuels war

Pope Leo XIV issued his most significant document to date, *Magnifica Humanitas*, on May 25, warning of a 'culture of power' where violence and limitless technological advancement threaten human dignity, especially for the poor. The encyclical argues that war is no longer a justifiable solution to disputes and that humanity must prioritize dialogue, diplomacy, and forgiveness instead. Leo XIV stated that the 'just war' theory, often used to justify military action, is now outdated and called for greater regulation of AI technology, emphasizing transparency and checks on private companies controlling its development. The pope framed AI’s rise as a moral choice for humanity, either to 'construct a new Tower of Babel'—dominating technology like a god—or to 'rebuild Jerusalem,' fostering fraternal coexistence under divine guidance. He condemned the concentration of AI power and profits in the hands of a few, urging states to impose stricter standards. Leo XIV also addressed AI’s environmental impact, labor effects, and gender equality, calling for equal pay and rights for women. In the final chapter, the encyclical links the digital revolution to modern conflicts, highlighting cyberattacks, disinformation, and automated warfare as growing threats. Pope Leo XIV urged the construction of a 'civilization of love' as an alternative to domination, arguing that technology must serve humanity’s well-being over economic or private interests. The document was signed on May 15, marking the anniversary of Pope Leo XIII’s landmark encyclical *Rerum Novarum*. Leo XIV’s critique may provoke controversy, particularly among U.S. officials like Vice President JD Vance, who have invoked the 'just war' theory to defend military actions, including the Iran conflict. The pope has repeatedly condemned U.S. military operations in Iran and other regions, framing peace as a shared responsibility rather than a temporary respite between wars.
