Personal Knowledge System

The design and practice of building a personal infrastructure for capturing, organizing, and retrieving knowledge — evolving from note-taking apps (Notion, Obsidian) toward AI-native systems that actively synthesize and connect information. The Karpathy Pattern applied to personal knowledge: instead of a static index, an LLM continuously integrates new information into an evolving graph of concepts and entities. This wiki itself is an instance of a personal knowledge system. Related to Learning as Meta-Skill, 內容護城河：AI 時代個人影響力的核心策略, and 隱性知識：無法言說的人類智慧.
