Pope Leo's First Encyclical Challenges Market-Driven AI, Drawing Comparison to Tower of Babel

Pope Leo XIV has issued his first encyclical, titled Magnifica Humanitas, directly challenging the idea that markets alone can be trusted to guide the development of artificial intelligence, according to analysis in Project Syndicate. The document rejects what the commentary describes as "Chicago School economics"—the view that prices and profit incentives are sufficient to manage society's technological future. Instead, the pope argues that AI raises questions about human dignity and social order that cannot be answered by market mechanisms alone.

The encyclical invokes the biblical story of the Tower of Babel, in which humanity, united by a single language and ambition, attempts to build a tower to heaven. God punishes the builders for their hubris by fragmenting them into different languages and cultures. The pope explicitly uses this parable to frame the stakes of artificial intelligence: will the technology be humanity's salvation, as its advocates claim, or will it lead to damnation, as skeptics fear.

The timing and content of the encyclical signal a significant shift in Vatican messaging on technology. Previous popes have addressed scientific and technological change, but rarely with such direct opposition to market-driven frameworks. Pope Leo's intervention places the Church in explicit tension with Silicon Valley's dominant philosophy and with the economic logic that has governed AI development in the United States and Europe.
