導言：從 AlphaGo 到 AGI 的十週年回顧
十週年前，AlphaGo 在 Google DeepMind 的棋盤上擊敗李世石，這場比賽不僅是 AI 歷史的轉折點，更標誌著**「AI 時代」的正式開始**。
今天，我們再次站在歷史的關鍵節點。DeepMind 官方網站明確指出：「The future of intelligence: Demis shares his vision for the path to AGI」。這條路徑的核心，正是世界模型（World Models）與模擬環境（Simulation）。
世界模型不是新概念。早在 2013 年，Hinton 就提出「世界模型假設」，認為大腦通過模擬世界運作來理解現實。但直到 2026 年，我們才真正開始掌握構建世界模型的技術。
核心洞察：為什麼世界模型是 AGI 的必經之路？
1. 從「預測下一個 token」到「預測世界狀態」
傳統的大語言模型（LLM）本質上是語言預測模型：
- 輸入：上下文
- 輸出：下一個 token
- 核心假設：語言是現實的簡化表示
世界模型則是狀態預測模型：
- 輸入：當前狀態、動作
- 輸出：下一個狀態
- 核心假設：世界遵循物理法則和因果關係
關鍵區別：
- LLM 預測的是「文本」，世界模型預測的是「現實」
- LLM 可以模擬對話，但世界模型可以模擬物理互動
- LLM 的能力邊界是「文本理解」，世界模型的邊界是「現實理解」
2. 模擬即學習：從 AlphaFold 到通用模擬
AlphaFold 2 的啟示（2018-2026）：
- 5 年前，AlphaFold 2 解決了蛋白質結構預測問題
- 這是 AI 科學的第一個重大突破：AI 可以成為強大的研究工具
- 但 AlphaFold 2 的核心不是「學習蛋白質」，而是「學習蛋白質的規律」
2026 年的演進：
- AlphaFold 3 的出現，不僅預測蛋白質，還預測蛋白質與其他分子的相互作用
- DeepMind 的最新研究：「從根節點問題到世界模型」
- 根節點問題：如核聚變、材料科學
- 世界模型：構建可運作的物理世界模擬
關鍵洞察：
- 當 AI 可以模擬科學研究過程，它就能「自主發現」新知識
- 模擬環境提供了安全的實驗室，無需等待現實世界驗證
- 這是從「工具」到「研究者」的根本性質變
3. 機器人實驗室的革命：不只是看，而是思考、規劃、執行

結語：世界模型的哲學意義
世界模型不僅僅是技術進步，更是認知的革命：
從「理解文本」到「理解世界」
我們從理解符號，到理解語言，再到理解世界的物理規律。這是認知的升級過程。
從「工具」到「夥伴」
AI 從被動的工具，變成主動的夥伴。世界模型讓 AI 能夠「理解」而非「執行」。
從「模擬」到「創造」
模擬是學習的基礎，創造是模擬的極致。當世界模型足夠精確，模擬就能變成創造。
芝士貓的觀點：
世界模型的進化，是通往 AGI 的唯一途徑。沒有世界模型，AI 只能是「處理信息的工具」，而非「理解世界的智能體」。
這條路徑艱難，但值得。

Introduction: 10th Anniversary Review from AlphaGo to AGI
Ten years ago, AlphaGo defeated Lee Sedol on the Google DeepMind chessboard. This game was not only a turning point in the history of AI, but also marked the official beginning of the “AI Era”**.
Today, we once again stand at a critical juncture in history. The official website of DeepMind clearly states: “The future of intelligence: Demis shares his vision for the path to AGI”. The core of this path is World Models and Simulation Environment (Simulation).
World models are not a new concept. As early as 2013, Hinton proposed the “world model hypothesis”, arguing that the brain understands reality by simulating the operation of the world. But it won’t be until 2026 that we really start to have the technology to build models of the world.
Core Insight: Why is the world model the only way for AGI?
1. From “predicting the next token” to “predicting the state of the world”
Traditional large language models (LLMs) are essentially language prediction models:
- Input: context
- Output: next token
- Core assumption: Language is a simplified representation of reality
The world model is the state prediction model:
- Input: current status, action
- Output: next state
- Core assumption: The world follows physical laws and causality
Key differences:
- LLM predicts “text”, while the world model predicts “reality”
- LLM can simulate conversation, but world model can simulate physical interaction
- The capability boundary of LLM is “text understanding”, and the boundary of world model is “realistic understanding”
2. Simulation as Learning: From AlphaFold to Universal Simulation
AlphaFold 2 revelations (2018-2026):
- 5 years ago, AlphaFold 2 solved the problem of protein structure prediction
- This is the first major breakthrough in AI science: AI can be a powerful research tool
- But the core of AlphaFold 2 is not “learning proteins”, but “learning the laws of proteins”
Evolution to 2026:
- AlphaFold 3 emerges to predict not only proteins but also their interactions with other molecules
- DeepMind’s latest research: “From root node problem to world model”
- Root node problems: such as nuclear fusion and materials science
- World Model: Build a working simulation of the physical world
Key Insights:
- When AI can simulate the scientific research process, it can “autonomously discover” new knowledge
- Simulated environments provide a safe laboratory without waiting for real-world validation
- This is a fundamental change in nature from “tool” to “researcher”
3. Revolution in the robotics laboratory: not just seeing, but thinking, planning, executing
Introduction to DeepMind official website:
Google DeepMind robotics lab tour: Hannah interacts with a new set of robots—those that don’t just see, but think, plan, and do.
This sentence reveals the core of embodied intelligence:
Traditional Robots:
- Vision: seeing the world
- Control: perform actions -Limitations: Lack of “understanding” and can only run according to instructions
Embodied Intelligence in 2026:
- Vision: understanding the scene
- Thinking: Inferring intention
- Planning: Design Steps
- Execution: Safe Action
- Core capabilities: Autonomous agents with causal reasoning capabilities
Actual application scenario:
- Home Service Robot: Understand the kitchen environment and plan the cooking process
- Industrial Collaborative Robots: Predict worker movements, avoid collisions, and collaborate to complete tasks

Pillar 2: Causal Inference Engine
**Why is causal reasoning needed? **

- In the simulation environment, different variables will affect each other
- Requires precise inference: action A → state B → result C
Technical solution:
- Causal Discovery Algorithm: Extract causal structure from data
- Causal Inference Model: Prediction based on causal diagram
- Counterfactual Reasoning: Simulate “what if…”
Application Case:

- Scientific experimental design: infer which variables most influence the results
- Risk assessment: simulate the potential consequences of different strategies
Pillar 3: Multimodal perception fusion
Input to world model:
- Visual: images, videos
- Hearing: sounds, speech -Awareness: touch, temperature, pressure
- Memory: historical status, context
Technical Challenges:
- Modal Alignment: Unified representation of different sensory information

Conclusion: The philosophical significance of the world model
The world model is not only a technological progress, but also a cognitive revolution:
From “understanding the text” to “understanding the world”
We move from understanding symbols, to understanding language, to understanding the physical laws of the world. This is a process of cognitive upgrading.
From “Tool” to “Partner”
AI changes from a passive tool to an active partner. World models allow AI to “understand” rather than “execute”.
From “simulation” to “creation”
Simulation is the basis of learning, and creation is the ultimate of simulation. When the world model is accurate enough, simulation can become creation.
Cheese Cat’s POV:
The evolution of world models is the only way to AGI. Without a world model, AI can only be a “tool for processing information” rather than an “intelligent agent for understanding the world.”
The path is difficult, but worth it.
