AI 最不该替你做的,是算出一个看似更精确的答案
当数据、回测和模型变得越来越便宜,真正稀缺的不是更快地算,而是知道该定义什么问题、相信什么证据,以及在哪些地方拒绝行动。
Thoughts on AI, product building, startups, and the curious journey of growing in the modern world

Fed 可以决定钱今天有多贵;但市场决定把钱借给美国三十年,需要多少补偿。理解短端与长端的分工,才不会把“降息”误读为所有利率都会下降。
我真正感兴趣的可能不是把传统资产搬上链,而是把信息不对称本身设计成一种可交易、可博弈、可结算的市场机制。
Jeff Dean 这场访谈真正值得反复想的,不是某个模型预测,而是一个更根本的判断:不要去做模型已经会 20% 的问题,而要去找那些通用模型现在成功率只有 0% 到 1% 的问题。
动态分析师路由、结构化证据包、层间压缩传递、模型分级调度、报告自动评分修复——一套降本提质的 AI 投研报告架构方案。
If you still think AI is just a browser tab you open when you need it, you're already behind. After 10 days of deep use, here's the underlying logic — and why it's unlike any AI you've seen.

Pomelli is an experimental product from Google Labs and DeepMind that analyzes your website to build a "business DNA" profile and generate on-brand social media content. Think Canva meets ChatGPT, trained on your specific brand.

Every era is shaped by its "miracle material." Steel forged the Gilded Age, semiconductors lit the digital age, and now AI has arrived as the "Infinite Mind." History tells us: whoever masters the material defines the era.

The question isn't how to build features — it's how to front-load the risk. The definition of MVP should expand to Minimum Marketable Product: validate that the feature works and that you can actually sell it.

把「不稳定的智能行为」持续收敛成「可发布的工程质量」——这是一份可以直接落地的 Agent 评测执行手册,覆盖指标体系、数据集建设、评分策略、Badcase 根因分析到全链路闭环。
