Pope Leo calls for the disarmament of AI: ‘Machines are tools, not persons’

What happened

Pope Leo XIV urged the global community to disarm artificial intelligence, specifically calling for a ban on lethal autonomous weapons. In his recent Papal Address, he emphasized that AI systems are tools and not persons, asserting that humans must guide, modify, or reject AI applications when necessary. The Pope’s call targets the upcoming United Nations meeting in Geneva, where member states will discuss measures to regulate AI weaponization.

Why it matters

This is a rare intervention from a major moral authority into AI governance, putting pressure on policymakers to consider ethical boundaries for AI use in military and potentially civilian contexts. The call reinforces that lethal autonomous systems cross a critical line raising new accountability and safety questions. Businesses and governments involved in AI weapon development face heightened scrutiny and possible regulatory pushback that could slow deployment or increase compliance costs.

What to watch next

Watch for how the UN delegates respond in Geneva and whether any binding agreements or frameworks emerge restricting autonomous weapons. This could set precedent for other AI regulations affecting sectors ranging from defense to industrial automation. Funders and builders working on AI-enabled military tech should prepare for tougher standards and increased public debate about AI’s role in conflict.
