A recent article describes how the open internet is transitioning towards deglobalization due to policy shifts among leading AI powers, manifesting as an "algorithmic iron curtain" through targeted restrictions on frontier AI models. The United States has moved from open science to strict containment, with labs like OpenAI and Anthropic implementing aggressive geo-blocking that cuts off cloud API access to advanced models for users in adversarial nations. Beijing has erected strict ideological barriers under its generative AI regulations, requiring models to reflect socialist core values, blocking foreign players like OpenAI, and operating domestic giants like Baidu’s Ernie Bot within a controlled national intranet. The European Union AI Act has created a defensive wall of compliance through stringent copyright rules and data audits, prompting Western tech firms to delay or withhold advanced multimodal tools in Europe. This shift is driven by frontier AI's reliance on highly concentrated, resource-intensive, and significantly expensive computing power, leading governments to view advanced software as a sovereign weapon rather than a bridge for global connection. The reversal is attributed to intense competitive anxiety surrounding intellectual property, as AI models cost billions of dollars and are vulnerable to digital piracy.
