Pope Leo XIV just dropped the Catholic Church's most explosive critique of technology in over a century. His first papal encyclical, Magnifica Humanitas (Magnificent Humanity), takes a massive swing at Big Tech, comparing Silicon Valley's relentless AI race to the biblical construction of the Tower of Babel. If you think a letter from the Vatican has zero relevance to the modern software stack or venture capital portfolios, you're dead wrong. This document is a live wire aimed directly at the economic and military forces driving artificial intelligence.
The real intent behind this sweeping 42,300-word document isn't to ban algorithms or demand a return to the dark ages. Pope Leo XIV, the first American pope, signed this text exactly 135 years after his namesake, Pope Leo XIII, published Rerum Novarum—the landmark 1891 letter that defended workers' rights during the height of the Industrial Revolution. This isn't an anti-tech rant. It's a highly sophisticated, deeply researched attack on who owns the tech, who profits from it, and who gets crushed underneath it.

The Illusion of Neutral Technology
A common defense among tech executives is that code is neutral; it's just math. Pope Leo flatly rejects this. The encyclical states that technology is never neutral because it inherently reflects the biases, financial incentives, and political motives of the people who fund and build it.
When a tiny handful of corporations control the world’s computational infrastructure, large language models, and data pipelines, they acquire massive, unchecked power. This concentration of resources creates a new form of colonial dominion. The Vatican isn't just worried about rogue killer robots; it's targeting the everyday corporate structures that use automated systems to squeeze human workers. To read more about the context here, The Verge provides an excellent summary.
To drive this point home, the Vatican invited Christopher Olah, a co-founder of the AI lab Anthropic, to speak at the official presentation of the encyclical. It was a bizarre, historic scene. A Silicon Valley pioneer standing inside the Vatican, agreeing with a pope that the systems we are building are so complex that even their creators don't fully understand them. Olah noted that AI models aren't engineered like airplanes; they are grown on vast troves of human thought, turning them into weird, unpredictable mirrors of humanity.
The Reality of Digital Slavery
We hear constantly about how AI will optimize workflows, automate boring emails, and maximize corporate efficiency. Pope Leo looks at the exact same data and sees a looming "social calamity." He zeroes in on a hidden aspect of the tech supply chain that Silicon Valley prefers to ignore: the brutal human labor required to keep the cloud running.
The text exposes what the Pope calls new forms of digital slavery. This includes thousands of young people in developing nations working for pennies under terrible conditions to label data and moderate graphic content. It also includes children mining rare earth minerals to build the hardware that processes these models. The encyclical notes that human bodies are being systematically worn down just so computational flow can continue without interruption.
When efficiency becomes the ultimate metric of human value, people start viewing themselves as projects to be optimized rather than actual human beings built for community. If an executive replaces an entire department with an API endpoint just to bump quarterly profit margins, that choice isn't just an economic calculation. It's an ethical failure.
Key Critical Risks Outlined in Magnifica Humanitas
- Erosion of Human Judgment: Automated answers eliminate the friction, patience, and critical thinking required to find actual truth, making societies incredibly vulnerable to cheap algorithmic lies.
- Simulated Empathy Without Relationship: Vulnerable, lonely people are increasingly turning to AI chatbots for emotional support or spiritual guidance, mistaking a statistical prediction of care for genuine human interaction.
- Asymmetric Power Concentration: The staggering cost of compute means data wealth sits in the hands of an elite few, driving deeper global inequality instead of fixing it.
- The Abdication of Military Accountability: Automating life-or-death decisions removes the essential human burden of guilt and responsibility from warfare.
The Demand to Disarm AI
The most politically charged language in the document centers on warfare and the Pentagon's rush to integrate machine learning into tactical systems. Pope Leo uses a deliberate, aggressive word: AI must be disarmed.
This goes far beyond standard regulatory red tape or voluntary corporate safety pacts. Disarming AI means stripping it away from pure military dominance and aggressive corporate competition. The Pope states explicitly that it is entirely impermissible to hand over irreversible, lethal decisions to an artificial system. No algorithm can ever make war morally acceptable.
This stance puts the Vatican on a direct collision course with global defense policies. The Pentagon has spent billions securing contracts with major tech firms to deploy software across classified settings. By framing autonomous systems as tools of exclusion and death, the Church is pushing tech workers to question the moral cost of the defense contracts keeping their employers profitable.
Moving Beyond Abstract Ethics
If you build software, manage data, or deploy automation, the Pope’s message isn't a vague suggestion to write a corporate code of ethics. We've seen how easily those papers are filed away and ignored. The encyclical demands hard, structural limits.
If you are an engineer or product designer, you hold a spiritual responsibility. Every single optimization choice, every dataset you select, and every guardrail you remove reflects a specific vision of humanity. If your system forces a worker to adapt to the grueling speed of a machine rather than making the machine support the worker, you're building a tool of subjugation.
Stop treating ethics as a post-launch patch. It has to be baked into the architecture from day one. Build systems that respect human limitations like aging, sickness, and rest instead of treating those limitations as bugs to be fixed through algorithmic optimization. The next step isn't waiting for governments to pass laws that tech lobbyists will inevitably rewrite. It's making the conscious, professional choice to refuse to build tools that replace human judgment, exploit hidden labor, or turn human life into automated data points.
