Pope Leo Warns Silicon Valley Is Building a New Tower of Babel – 5 Key Warnings from Vatican Encyclical AI | Today’s news
Pope Leo XIV has issued the Catholic Church’s most important statement on artificial intelligence, comparing the unchecked ambitions of the global tech industry to the biblical builders of the Tower of Babel – and calling for a fundamental reckoning with human dignity in the age of artificial intelligence.
What is Magnifica Humanitas? Historical encyclical on artificial intelligence of Pope Leo XIV

The Vatican issued Magnifica Humanitas — Latin for “magnificent humanity” — on May 19, 2026, making it the first papal encyclical devoted primarily to artificial intelligence. Pope Leo XIV, the first American pope, signed the 42,300-word document in St. Peter’s Basilica on May 15, 2026, exactly 135 years after his namesake, Pope Leo XIII, issued Rerum Novarum, the seminal 1891 encyclical on labor rights during the Industrial Revolution.
The parallel is intentional. Like Leo XIII. dealt with the upheavals of mechanized work in the 19th century, Leo XIV. he stakes out the moral position of the Catholic Church at what he sees as a civilizational inflection point. The document is addressed to the world’s 1.4 billion Catholics, but its arguments reach far beyond the pews.
The Tower of Babel: Pope Leo’s Central Warning About Artificial Intelligence and Power
The encyclical’s most arresting image is the Tower of Babel, the biblical account from Genesis in which a united humanity attempts to build a structure “whose top reaches to the heavens” — only for God to scatter them across the earth in many languages and cultures.
Leo uses this story to warn against the homogenizing tendencies of artificial intelligence: the concentration of power in the hands of a few, the erosion of cultural diversity, and the arrogance of believing that human-made systems can replace deeper moral and spiritual truths. As global culture homogenizes and technology becomes a sort of universal language, the Pope’s call for humility and pluralism stands in stark contrast to the ambitions of the world’s leading technology companies.
The link also serves as a reminder that the ethical and social dilemmas posed by AI are not new. Humanity has previously navigated the tension between technological ambitions and human limitations.
Artificial intelligence is not human: The basic argument of the encyclical
At the heart of Magnifica Humanitas is a firm philosophical statement: artificial intelligence is not human. However much artificial intelligence systems approach human cognition or even seem to copy emotional life, they remain categorically different from persons in Leo’s view.
This is not a trivial point. Some researchers and prominent thinkers in the field have begun to question whether artificial intelligence systems can actually experience or express human emotions. The encyclical directly contradicts this view and draws a clear line between machine and person – a line that the Pope sees as the basis of any coherent ethics for the digital age.
The document uses the word “dignity” 100 times.
Pope Leo’s five key warnings about artificial intelligence
The encyclical sets out a structured set of risks that, according to Leo, a global race of AI poses to human society:
1. AI distorts human judgment
By providing immediate answers, AI systems risk undermining creativity, discernment and what the Pope calls the patience needed to seek the truth.
2. AI simulates relationship-less care
Vulnerable users, especially those who turn to chatbots for emotional support or spiritual guidance, can mistake artificial empathy for real human connection.
Data, computing power, and regulatory influence are concentrated among a small number of actors, exacerbating existing differences rather than resolving them.
4. AI destabilizes democracy
The amplification of disinformation and the obfuscation of fact and fiction directly threatens democratic societies.
The sharpest line of the encyclical deals with autonomous weapons and lethal decision-making with the help of AI: “No algorithm can make war morally acceptable.”
Workers, wages and the new digital serfdom
Magnifica Humanitas pays considerable attention to the world of work and reflects the tradition of Catholic social teaching that goes back to Rerum novarum. Leo acknowledges that economic and technological systems have always undergone radical transformation, but insists that the basic dignity of the worker—including fair wages—must remain central to any new economic order.
He is particularly emphatic about what he calls the “new forms of slavery” associated with the digital economy. These include young people employed at minimum wage in data tagging and content moderation roles, and children working in hazardous conditions to extract the rare earth materials that underpin the artificial intelligence industry.
“The bodies of these people are scarred, wounded and worn, so that the computational flow can continue without interruption,” the Pope writes.
About power, morality and who gets to define the values of artificial intelligence
One of the most politically charged passages of the encyclical deals with the question of whose moral framework will be built into artificial intelligence systems. Leo acknowledges that AI “can be a valuable tool” and warns that the technology “tends to amplify the power of those who already have economic resources, expertise and access to data.”
Without sufficient oversight and transparency, “those who control AI impose their own moral vision, which becomes the invisible infrastructure of these systems.”
His conclusion is unsparing: “A more moral AI is not enough if a few people determine that morality.”
Children, Screens and AI: The Pastoral Dimensions of Magnifica Humanitas
The encyclical is not just a document of extensive moral philosophy. It also deals with the practical realities facing Catholic families around the world. Leo conducts research on the impact of technology on children’s development and warns that early and uncontrolled access to smartphones leaves children vulnerable to addiction, bullying and sexual exploitation.
It also raises concerns about young people using AI chatbots as a substitute for human friendship or professional mental health support — a phenomenon that observers have noted is already widespread outside Catholic communities.
No technology can deprive man of his dignity: The humanistic core of the encyclical
We run through each section of Magnifica Humanitas with a single insistence: the value of human beings cannot be measured in units of productivity or computing power.
“However, the value of persons does not depend on what they achieve or produce,” writes Leo. “There are rights that apply to everyone simply by virtue of being human.”
Humans, the Pope acknowledges, are increasingly outmatched by the technology they’ve created — if performance is measured in cold, narrow terms. But Leo writes with love for human vulnerability and finitude. The document ends with the wish “that we may bear witness to the greatness of humanity in which God dwelt.”
The reaction of Silicon Valley and the strategic position of the Vatican
The Vatican’s decision to invite Christopher Olah, the co-founder of Anthropic, to attend Monday’s formal presentation of the encyclical was widely seen as a signal of the church’s intent.
Unlike Pope Francis’ 2015 climate encyclical Laudato Si’, where no oil company representatives were present, Magnifica Humanitas was unveiled with a prominent AI industry figure in the room.
“With this document, Pope Leo has now established himself as one of the leading figures on the ethics of artificial intelligence,” Axios quoted Meghan Sullivan, director of Notre Dame’s Institute for Ethics and the Common Good, as saying.
According to an Axios report, Mirela Oliva, a philosophy professor at the University of St. Thomas, said Leo’s encyclical should be read less as a rejection of artificial intelligence than as a call to shape an “artificial intelligence era” around human dignity. “The Pope is calling for new guidelines for artificial intelligence, and these new guidelines are to be developed from the bottom up rather than the top down.”
Axios quoted Dan Rober, a professor of Catholic studies at Sacred Heart University, who suggested that the encyclical’s most lasting impact may lie in whether Leo’s language begins to shape debates over the regulation of artificial intelligence. He added that the Pope’s warnings about children, screens and artificial intelligence platforms may “resonate beyond Catholic circles”.
How does the magnificent humanity compare to the new things?
The 135-year parallel between the two encyclicals is the document’s most ambitious historical claim. Rerum Novarum didn’t immediately transform labor law—but for decades its vocabulary of “fair wages” and workers’ rights permeated political debate around the world.
According to a New York Times report, Luke Burgis, founder of the Cluny Institute, which studies the relationship between faith, reason and technology, said: “This encyclical is a live wire that really has the potential to change what is being built in Silicon Valley. It could help give people the vocabulary to understand new things, just as Rerum Novarum helped people understand the concept of a fair wage.”
However, he warned that the change would not be quick. “The Church is just beginning its work here. It needs to connect with a powerful counterforce that currently has the upper hand, both in capital and calculation.”
Key things
- AI is a tool, not a person, and should never be treated as such.
- The dignity of every human being is non-negotiable, regardless of economic productivity.
- Workers in the AI supply chain deserve protection and fair wages.
- Power over artificial intelligence systems must not be concentrated in the hands of a few corporations or states.
- Children require protection from unsupervised exposure to artificial intelligence and digital platforms.
