Pope Leo XIV challenged Nvidia CEO Jensen Huang’s opposition to new AI regulations during a September 28, 2026, press exchange aboard the papal flight returning from France. Leo said warnings that artificial intelligence could pose serious risks to humanity should not be dismissed as "fake news," a position contrasting with President Donald Trump’s recent description of such concerns as a "hoax" at the United Nations. The Pope pointed to Nvidia’s Sentry monitoring system for AI agents as evidence of the tension between developing internal guardrails and rejecting government oversight. His position extends the themes of Magnifica Humanitas, a 42,300-word encyclical published May 25, 2026, calling for oversight of private AI developers, worker protections, safeguards for children and human control over weapons systems. A White House meeting scheduled for Tuesday will bring Trump together with Huang, Mark Zuckerberg, Dario Amodei and Greg Brockman to discuss AI policy, with House Speaker Mike Johnson warning that excessive regulation could weaken the United States’ position against China.
