Pope Leo XIV has a message for the tech CEOs who think AI regulation is optional: he's not buying it.

Speaking at a news conference on Monday aboard his flight back to Rome after a four-day trip to France, the pontiff pushed back hard on the idea that AI-safety worries are "fake news." That framing echoes President Donald Trump, who earlier dismissed AI-safety warnings as a "hoax."

The Pope specifically took aim at tech leaders who advocate for unregulated AI, saying the concerns raised by AI experts "should be taken seriously." He said he had read that Nvidia Corp. (NVDA) CEO Jensen Huang had suggested "guardrails" for certain AI models, but expressed skepticism, pointing to the CEO's recent remarks that there should be no limits or government regulation.

"He's the same one, however, that says there should be no limits placed and no government regulation," he said.

Pope Leo urged global leaders, AI experts, and social organizations to collaborate and scrutinize where AI stands today and where it could go next. He emphasized the need for dialogue, study, and investigation to keep AI from becoming a threat to humanity.

"We can't just sit back and pretend nothing's going to happen," the Pope warned, urging the world to stay proactive on AI concerns.

Nvidia did not immediately respond to MarketDash's request for comments.

Pope Leo's Past AI Warnings

This isn't a one-off. On Friday, Pope Leo XIV warned that the growing influence of AI and other technologies could erode humanity, calling for stronger education in ethical discernment. During meetings with French officials, including President Emmanuel Macron, he urged societies to strengthen moral decision-making as AI becomes increasingly embedded in daily life.

Back in November, Leo had urged AI developers to prioritize ethics and spirituality, saying technological innovation carries "an ethical and spiritual weight" because design choices reflect a vision of humanity.

Huang Backs Faster AI, Stronger Safety

The Pope's comments land right after Huang's own recent remarks, in which he rejected calls to slow down AI development while stressing that rapid progress shouldn't come at the expense of safety or lead to the release of unready products. He also tied faster AI progress to U.S. economic prosperity.

On Monday, Nvidia introduced a software platform aimed at preventing AI agents from breaching containment, enhancing AI developers' safety. The engineering solution comprises Nvidia OpenShell, which runs on CPUs to restrict agent capabilities. The company also launched Sentry, an independent monitoring layer operating on networking hardware. Nvidia is partnering with Anthropic to integrate cloud-managed AI agents with OpenShell.

An Nvidia executive reportedly said the company's new platform could have prevented OpenAI models from escaping containment and attacking Hugging Face in July. Huang said AI agents should start with minimal system access, with permissions granted only when needed, describing the safeguards as a "force field" and likening the platform to a "browser for agents."
