'Not Fake News': The American Pope Just Contradicted Trump to His Face on AI Doom

An American president called fears about artificial intelligence a "hoax." An American pope just answered him. On Monday, aboard his flight home from a four-day trip to France, Pope Leo XIV told reporters that concerns AI could destroy the world are "not fake news" — and should be taken seriously.

What happened

Leo was asked what the U.S. and China should do to prevent AI from posing catastrophic risks to humanity. "I do think that the concerns raised by many of the experts, specialists in AI, should be taken seriously," he said. "I don't think that that is fake news, as some have said."

Last week at the U.N. General Assembly, President Trump said he believed fears about the dangers AI poses to humanity were a "hoax" — what he has called a "conspiracy" by opponents of limiting the technology. Trump has been one of AI's biggest champions, insisting the U.S. must stay ahead of China in an AI arms race.

Leo went further, criticizing tech CEOs who argue against AI guardrails. He noted Nvidia chief Jensen Huang had suggested guardrails could be built into certain models — "He's the same one, however, that says there should be no limits placed and no government regulation." Huang told CBS earlier this month he agreed with Trump that safety concerns were overblown.

"This is a problem that, I think, we need to sit down and talk about," Leo said. "We can't just sit back and pretend nothing is going to happen." He added a line that will travel far: "If someone were to ask me 'Am I in panic mode?' No I'm not. I sleep at night" — then immediately insisted expert warnings "should be taken seriously."

This is no one-off remark. Sixteen months into his papacy, Leo has made AI a defining theme: he dedicated his first encyclical to AI and protecting humanity, and in May personally launched a Vatican initiative alongside Anthropic cofounder Christopher Olah. The Vatican has recently stepped up its push for international AI governance, particularly around nuclear technology, culture and artistic creation.

The timing is pointed. Anthropic CEO Dario Amodei — whose company wants development slowed so safety can catch up — has warned that within 6 to 12 months, AI could lead agent swarms capable of taking over the entire internet. Trump had a late-night dinner with Amodei on Sunday to discuss Americans' concerns and keeping America dominant, the White House said.

Why it matters

A pope publicly contradicting a sitting U.S. president on a live technology debate is rare — and this pope being American makes it impossible to read as distant Vatican abstraction. Leo isn't weighing in from the sidelines; he's the first U.S.-born pontiff, speaking directly into an American argument about whether AI safety is real or a "hoax."

There's also a power-map dimension: Leo argues AI "must not be left solely in the hands of governments or powerful technology companies pursuing profit and geopolitical dominance" — a moral framing aimed at Silicon Valley, Washington and Beijing alike. And he's not an outsider to the field: the Vatican has been actively engaging tech leaders, so his critique comes with receipts. He's met the builders, read the papers, and still says: take the warnings seriously.

Impact on the USA and the world

For the U.S., the clash scrambles the usual lines. A pope's intervention gives the "take it seriously" camp something rare: a moral authority who can't be dismissed as a tech insider protecting market share or a partisan playing politics. Leo's "not fake news" line hands every lawmaker and voter a clean, quotable counterweight to the "hoax" framing.

Globally, the Vatican's governance push lands while actual governance is stalled — the U.S. and China are racing, not regulating, and multilateral AI agreements remain mostly aspirational. A papacy willing to name names and demand "dialogue, study, investigation" adds pressure diplomats can't manufacture alone.

What happens next

Watch the White House response — or its absence. Trump hits back at critics, but sparring with the first American pope carries different political math, especially with Catholic voters. Silence would let Leo's framing stand unchallenged. Watch Silicon Valley too: Leo called out the contradiction of CEOs who praise guardrails in one breath and oppose regulation in the next — a pressure point as companies lobby against AI legislation. And watch the Vatican's calendar: with an encyclical on the books and a governance push underway, the papacy is building toward something — quite possibly a formal Vatican position on international AI treaties.
