AI 把「执行」变成了大宗商品——钱正在流向两端：上游卖铲子，下游卖信任 AI has turned execution into a commodity — the money is flowing to the two ends: selling shovels upstream, selling trust downstream

三份深度研究、322 条原始路径交叉去重后的全景图。骨架是淘金热价值链十层（L0-L9）：1849 年稳定赚钱的是卖铲子、牛仔裤和船票的人，AI 时代完全复刻。核心是路径浏览器——按「你是谁 × 启动门槛 × 赛道状态」筛出你能做的那几条。★＝金色卡片为「卖铲子」高毛利位，每条路径标注传统前身、典型数字与真实风险。 Three deep-research reports, 322 raw paths, cross-checked and deduplicated into one atlas. The skeleton is the gold-rush value chain, ten layers (L0–L9): in 1849 the steady money sold shovels, jeans and boat tickets — the AI era is a perfect replay. The core is the path explorer — filter by who you are × entry barrier × segment status to find the paths you can actually run. ★ gold cards mark the high-margin shovel positions; every path carries its pre-AI ancestor, real numbers and real risks.
