AI 成了外置的 System 2——它接管「怎么想」，认知产业的价值从中段塌陷，涌向两端 AI has become an external System 2 — it takes over the how of thinking, and the industry's value collapses in the middle, surging toward both ends

四大版图：价值链六节点（内容生产→变现，替代分档色标）、偏误 × 心智模型自查矩阵（选你最常犯的偏误，看对应的模型补丁与 AI 用法——本图独有交互）、认知资产负债表（什么在贬值/什么在升值）、赛道矩阵（按身份与预算筛选）。姊妹图 个人成长 growth 讲 AI 如何改造行为系统，本图讲 AI 如何接管思维本身。 Four maps: the six-node value chain (production → monetization, graded by substitution), the bias × mental-model self-check matrix (pick your usual bias, see its model patch and AI usage — this map's unique interactive), the cognitive balance sheet (what's depreciating, what's appreciating), and the segment matrix filterable by identity and budget. The sibling map growth covers AI rebuilding your behavior system; this one covers AI taking over thought itself.
