Italy remains the focus of the global ethical debate over future technology. Nobel laureates, religious leaders, and emeritus heads of state signed the "Rome Declaration for an Unarmed Peace", a critical declaration expressing an unprecedented warning: stop the AI-related arms race before it is too late. The summit, held between Castel Gandolfo and the Italian capital, was heavily influenced by Pope Leo XIV's encyclical "Magnifica Humanitas", which positioned Italian humanitarian diplomacy and the Vatican at the forefront of a global movement to protect mankind. The Declaration explicitly compares the emergence of AI to the rise of nuclear weapons during the Cold War, establishing it as the new arena of global strategic competition. Signatories and experts urge governments and Silicon Valley titans to promptly implement stringent governance measures, including legal liability for developers and an absolute ban on initiating self-improvement processes in AI systems without human oversight capable of "pulling the plug". With this historic declaration, Italy advocates for a new digital humanism, urging superpowers to defuse the technological threat while we still have the opportunity to do so.
