（旧金山/北京，综合报道）在近日接受本报专访时，全球 AI 芯片巨头英伟达首席执行官黄仁勋直言不讳，指出美国对华半导体出口管制政策已显示出严重的适得其反的效果。这位掌舵市值超万亿美元的公司的科技领袖警告说，不当的限制正在导致美国企业失去在全球最大人工智能市场的主导地位，而中国的技术实力正在加速在自主创新的轨道上取得突破。 ■ 政策反思：监管对美国企业 适得其反在两个小时的深度对话中，黄仁勋首次披露了关键数据：自2020年美国对中国发起技术管控以来，英伟达在中国AI芯片市场的份额从95%暴跌至50%。“这项政策不仅没有减缓中国的人工智能发展，还给美国公司造成了巨大损失，”黄仁勋透露。仅 H20 芯片的库存减记就达数十亿美元，相当于许多半导体公司的总市值。 这位硅谷传奇人物强调，中国拥有全球 50% 的 AI 研究人才和完整的产业生态系统。他特别提到了中国企业的突破性创新：DeepSeek 的原创研究正在被全球学者广泛研究，阿里巴巴的“Qwen”大模型展示了国际标准，华为甚至推出了性能超过英伟达的 AI 超级计算机系统。 ■ 6G 时代：中美 新战场在讨论未来技术格局时，黄仁勋将注意力转向了 6G 通信标准的竞争：“AI 和 6G 的深度融合将重塑全球通信基础设施。本次比赛的获胜者将拥有下一代技术的话语权。他指出，华为在 5G-AI 融合领域已经做出了超前布局，NVIDIA 必须加快创新步伐才能保持竞争力。 注意：术语 “话语权” 在英语中翻译为 “话语权”，这是一个音译，因为在英语中没有直接的对应物。然而，在上下文中，它可以理解为“发言权”或“影响的力量”。 面对失去价值 3 万亿美元的中国市场的可能性，黄仁勋坦言：“试图用其他市场来弥补在中国的损失，这是一个错误的命题。在这里，每年有 50 多家 AI 初创公司诞生。没有一家全球科技公司能够承受提款成本。 ■ 未来十年：AI 代理革命 从技术角度来看，黄仁硕预测，未来 5 到 10 年将见证“数字机器人”的全面崛起。这些具有自主推理能力的 AI 代理将渗透到所有行业，并重塑人类的工作范式。“真正的风险不是被人工智能取代，而是被掌握人工智能工具的人超越，”他强调。大多数 i全球…
