Marcus 和 Hassabis 点出了当前 LLM 的根本局限——文本无法替代真实体验，做 AI 研究或关注 AGI 方向的开发者值得深入理解世界模型为何是下一关键突破。
Gary Marcus 引用六年前的文章《AI 的下一个十年》，指出世界模型（World Models）的核心地位终于得到认可。DeepMind 的 Demis Hassabis 认为当前 AI 的局限在于语言只能描述世界，无法包含世界，而世界模型是他“最持久的热情”。语言模型从文本中吸收了远超预期的现实结构，但文本只是经验的压缩残渣，无法编码重量、抓握、平衡、摩擦等物理细节。世界模型旨在学习物理现实的隐藏语法——物体如何持续、力如何展开、空间如何随行动变化——这对于真正的智能至关重要，因为智能不仅是回答得好，更是知道下一步行动会带来什么后果。

six years ago world (cognitive) models were the centerpiece of my essay The Next Decade in AI. their time is finally coming. Rohan Paul @rohanpaul_ai Demis Hassabis on the limit in today’s AI: language can describe the world, but it cannot contain it - and why "World Models" are his "longest standing passion". Language models absorbed far more structure about reality from text than many researchers expected, because human language quietly carries physics, psychology, culture, tools, plans, and cause-and-effect. But text is still a compressed residue of experience, not experience itself. A sentence can say a cup falls from a table, yet it does not fully encode weight, grip, balance, friction, timing, sound, surprise, or the tiny motor corrections a body makes before it even notices them. The world is not only made of facts that can be named; it is made of constraints that have to be lived through, touched, predicted, violated, and repaired. That is why world models matter. They aim to learn the hidden grammar of physical reality: how objects persist, how forces unfold, how space changes when an agent moves, and how action creates feedback. Language models can often reason about the world because people have written so much about it. World models try to learn what the world is like before it becomes words. The difference is exactly what matters because intelligence is not just answering well; it is knowing what would happen next if you moved, reached, pushed, smelled, slipped, or failed. A mind trained only on descriptions may become brilliant at explanation. A mind trained on experience may become better at consequence. --- Full video from "Google DeepMind" and "Hannah Fry" YT channel (link in comment) Your browser does not support the video tag. 🔗 View on Twitter 🔗 View Quoted Tweet 💬 1 🔄 0 ❤️ 2 👀 115 📊 1 ⚡
