AI 击穿了知识的生意，却碰不到改变发生的地方——杠杆最高的干预，恰是 AI 最难替代的 AI has gutted the knowledge business, yet can't touch where change actually happens — the highest-leverage interventions are precisely the ones AI can't replace

四大版图：认知生产生命周期六阶段（输入→加工→输出→习惯→反馈→身份，红黄绿三档冲击色标）、「把人当系统」六模块（能量/注意力/知识/关系/财务/意义，附杠杆排序）、症状误诊表（你以为是懒，其实是系统病因）、赛道矩阵（按「我想提升什么 × 形态 × 状态」筛选）。红＝被击穿，黄＝被重构，绿＝护城河。 Four maps: the six-stage cognitive production lifecycle (input → processing → output → habits → feedback → identity, graded red/amber/green), the six modules of the human system (energy / attention / knowledge / relationships / finance / meaning, with leverage rankings), the misdiagnosis table (you think it's laziness; it's a systems failure), and the segment matrix filterable by what you want to improve × form × status. Red = gutted, amber = rebuilt, green = moat.

Chegg 市值 39 个月的蒸发幅度（$147 亿→$1.15 亿）——被 AI 击穿的最干净对照案例Chegg's market cap over 39 months ($14.7B → $115M) — the cleanest specimen of getting gutted by AI

Duolingo 日活（+36%，营收 +41%）；AI 把内容产能提高 17.6 倍——被 AI 放大的另一端Duolingo's DAU (+36%, revenue +41%); AI lifted content output 17.6x — the amplified end of the barbell

BetterUp 用户偏好：34% 只要真人教练、15% 只要 AI、51% 两者都要——「AI 打底、真人封顶」的民意基础BetterUp user preference: 34% human-only, 15% AI-only, 51% both — the mandate for 'AI floor, human ceiling'

Khanmigo 用户数——是原预期（10 万）的 14 倍；ChatGPT Study Mode/NotebookLM 同年跟进（口径：厂商披露）Khanmigo users — 14x the 100k forecast; ChatGPT Study Mode and NotebookLM followed the same year (vendor-reported)

口径警告：效果数据多为厂商披露（Coursera Coach +9.5% 通过率、BetterUp「降本 70%」均非独立研究）；负面证据来自学术研究（MIT EEG：ChatGPT 协助组在无 AI 测试中表现最差）。得到等中国平台数据非独立审计。本页数字优先采信来源甄别过的研究口径。 Basis warning: efficacy numbers are mostly vendor-reported (Coursera Coach's +9.5% pass rate and BetterUp's '70% cost cut' are not independent research); the negative evidence is academic (MIT EEG: the ChatGPT-assisted group performed worst on later unaided tests, with lower brain activity). Chinese platform figures are unaudited. This page prefers source-vetted bases.
