美国专家来中国转了一圈：AI比赛已经结束了

Core Viewpoint - The article discusses the significant gap between the AI capabilities of China and the United States, suggesting that the competition may have already concluded in favor of China due to its superior energy infrastructure and investment in sustainable energy sources [2][6][26]. Group 1: Energy Infrastructure - The article highlights that energy is a critical factor in AI competition, with China having resolved its energy issues through substantial investments in nuclear and hydropower, resulting in a stable and low-cost electricity supply [22][30]. - In contrast, the U.S. faces challenges with an aging power grid, where 70% of transmission lines are over 25 years old, making it difficult to meet modern energy demands [31][32]. - The U.S. struggles with slow approval processes for energy infrastructure projects, often taking over a decade to complete, which hampers the development of renewable energy sources [33][36]. Group 2: AI Development and Market Dynamics - Chinese AI companies are noted for their strong capabilities, but they face challenges in profitability due to lower pricing of products and services [17]. - The article emphasizes that the U.S. tech companies prioritize short-term profits over long-term infrastructure investments, which could hinder the advancement of AI technologies [46][48]. - The disparity in government involvement in energy and AI infrastructure between China and the U.S. is highlighted, with China benefiting from centralized planning and investment [45][46]. Group 3: Expert Opinions - Rui Ma, a prominent AI expert, expressed that energy supply is taken for granted in China, while in the U.S., there is ongoing debate about the impact of AI on energy consumption and grid limitations [23][24]. - The article references AI pioneer Geoffrey Hinton's criticism of U.S. tech companies for their short-sightedness regarding AI development and safety, indicating a potential shift in focus towards more responsible AI practices [50][56].
