Reactions to an interview with Tulong (Yang Ying) — Tsinghua biology, a Pittsburgh PhD decoding the brain for the US military, who came home and built four companies in a world of "accountants driving Ferraris and influencers showing up with gangster bosses." The title asks why she makes money at everything; she's the one who admits the jewelry line sold zero. What's actually valuable isn't a Midas touch — it's an operating system she can carry from neuroscience into skincare, books, and courses.

课代表立正这期访谈，嘉宾是屠龙（杨滢）——清华生物、匹兹堡脑科学博士、给美军解码大脑，回国后却在一个"会计开法拉利、网红带黑社会大哥上门"的江湖里连开四家公司。标题问"为什么她干啥啥赚钱"，但她自己交代过卖首饰一件没卖出去。真正值钱的不是某种点石成金的天赋，是一套能从科研搬到美妆、图书、课程的操作系统。我顺着完整字幕又抠了一层：她到底带了什么下场。

I listened to an episode on AI and wealth redistribution — the finance podcast 十分吸引 crossed with 听懂涨声 — and the best part was the history: how railroads, electricity, and the internet each reshuffled wealth. I dug a layer under their account and made it harder: the reshuffle runs one logic every time — technology rewires the economic network, the old bottleneck fails, a new one gets priced, and wealth follows the bargaining power. Railroads rewired the goods network, electricity the energy network, the internet the information network, AI the task network. The first three eventually grew a new middle class, because those production modes needed armies of ordinary people. AI is heavy-asset and dispersive, so it may run only the concentration half and skip broaden-the-middle.

听《十分吸引》串台《听懂涨声》聊 AI 财富再分配，最有意思的是他们把铁路、电力、互联网三轮洗牌的机制层层拆解。每一次生产力基础设施的革命都是一次财富大洗牌：技术重写经济网络，旧瓶颈失效，新瓶颈拿到定价权。前三轮都是先集中、后扩散，靠的是新生产方式需要海量的人；AI 是重资产、离散型的，可能只走完集中那一半。这是我对这轮最不乐观的判断。

A group chat landed on a heavy question: once AI and embodied robots do most of the work and productivity explodes, do ordinary people actually get freer? Or do the gains flow to a few platforms, capital pools, and states, while everyone else goes from worker to managed case? The more I sat with it, the less I believed in an automatic utopia. The likely future is three paths braided together — AI dividend society, platform feudalism, and high-automation governance — and which one dominates decides whether AI frees people, or just frees productivity while people stay stuck.

A friend pinged me at midnight asking whether we should build a bot to follow Serenity, the supply-chain researcher who blew up on X, in and out of his trades. My first reaction was that it was pointless: a strategy that actually compounds gets quietly levered up, not broadcast. But by the end of the night I'd changed my mind. There is something worth distilling here — it just isn't in his holdings, it's in the order he asks his questions. So we turned that process into an open-source skill.

群里聊到一个很沉重的问题：AI + 具身智能把活都干了、生产力大涨之后，普通人会因此更自由吗？还是说红利全被大公司、大平台、大资本拿走，普通人只是从打工人变成被系统管理的人？我越想越觉得，未来不会自动走向乌托邦，而更可能是三条路线混在一起——AI 红利社会、平台封建主义、高自动化治理社会。决定 AI 时代是人被解放，还是生产力被解放了、人没有。

一个朋友半夜问我，要不要也做个工具去跟 X 上很火的 Serenity 买进卖出。我的第一反应是没意义：一个策略真能稳定赚钱，最理性的做法是闷声加仓，不会拿出来开直播。但聊到后面我改了主意。值得蒸馏的东西确实有，藏在他提问的顺序里，跟他的持仓没关系。我们把这套研究流程做成了一个开源工具。

你的优势是你的问题。二十五年真正会复利的不是信息量，是问出更好问题的能力。最后一个 workshop 是全课程唯一不用 agent 做的。

前八章的全部内容压缩成一个端到端流程。三家公司，一个决定。这一章本身就是 workshop——预计 4 到 8 小时，分多次完成。

单个 agent 是工具。有明确角色、交叉验证和显式交接的一组 agent，才能产生质变。五个模式覆盖 90% 的投资研究流程。

大部分投资者有的是信念，不是论点。把判断写下来、附上止损条件，是对自己记忆的问责——因为记忆会自我美化，信念会悄悄变形。

LTCM 1998 年清盘的时候，波动率指标从头到尾都很漂亮——它量的东西和真正杀死它的东西压根不是一回事。这一章讲波动率骗人的三个地方、四种真正的风险，还有怎么用 agent 做事前验尸。

DCF 里每个数字都是一个故事选择。Agent 算得又快又准，但它默认讲共识。你的工作是带自己的故事进去——以及找到估值暗中依赖的那个假设。

年报不用一行一行读，你要认的是形状。三张报表各管一件事，对不上的地方才值得你花时间。

股票是对未来现金流的权利——不是代码，不是图表。三种回报来源，五种优势类型，以及你在判断 agent 输出之前必须有的词汇。

投资场景里 agent 有四个角色——分析师、红队、导师、执行者，你怎么问决定激活哪一个。「能不能买」这种问法只用到了其中一个。

Your edge is your questions. What compounds over twenty-five years is not information — it is the capacity to ask better questions. The final workshop is the only one you do without an agent.

Everything from chapters 1 through 8 collapses into one end-to-end workflow. Three companies, one decision. This chapter IS the workshop — expected time: 4 to 8 hours across multiple sittings.

A single agent is a tool. A fleet with defined roles, cross-verification, and explicit handoffs is transformative. Five patterns cover 90% of investment workflows — but over-engineering the fleet is itself a form of procrastination.
