The method addresses a growing concern among policymakers, data center operators, and sustainability planners as AI's electricity demands surge and strain power grids in major markets.
UN University: 'Politics of Speed' — Governing AI in the Age of Algorithmic Conflict
The United Nations University published a major policy essay arguing that AI's pace of development has outrun governments' capacity to govern it, introducing the concept of "algorithmic conflict" — where AI systems themselves, not just the actors using them, drive geopolitical and social tensions. The paper calls for urgent international coordination to close regulatory gaps before they become permanent features of the global AI landscape.
