克拉克·克尔提出“多元大学”概念，重塑现代大学认知

1963年，美国加州大学校长克拉克·克尔在哈佛大学发表演说，后出版《大学之用》，首次提出“多元大学”概念。他认为，战后美国研究型大学不再是学者共同体，而是一个庞大机构复合体，兼具研究引擎、职业培训、资格认证、成人仪式和国家技术精英孵化器等多重功能。克尔以风趣著称，曾调侃大学面临的三大问题是“教授停车、校友体育、学生性事”，教职工是“因共同抱怨停车而团结的个人企业家”。1966年，因对自由言论运动态度温和，他被里根政府解雇，留下名言“我以被热情地解雇开始这份工作，也以被热情地解雇结束”。尽管言语幽默，克尔严肃指出，多元大学看似松散混乱，实为20世纪中期美国文明的关键制度枢纽，承担着知识生产、技术精英培养和民主公民塑造的重任。 #高等教育 #克拉克·克尔 #多元大学 #大学之用 #教育史 #加州大学 #学术思想 #美国大学

SAGA研究提出生成式AI视频来源归因新方法

来自arXiv的一项最新研究提出了名为SAGA的框架，用于对生成式AI视频进行来源归因，即通过技术手段识别生成视频所使用的基础模型。该研究由Rohit Kundu等五位作者完成，论文已在arXiv预印本平台发布。随着生成式AI视频内容日益增多，追溯其来源对于内容真实性验证、版权保护及安全监管至关重要。SAGA方法通过分析视频特征，可有效判断其由何种模型生成，为提升AI生成内容的透明度和可追溯性提供了新思路。该工作已被列为计算机科学领域热门论文，并提供了代码与数据链接。 #SAGA #AI视频 #来源归因 #生成式AI #arXiv #科技研究 #内容安全

This shapes how we describe your profile and what we show you next. A Yes — I have a brokerage or fund account B Not yet — I'm figuring out where to start Next → Question 1 of 4 How many investing philosophies do you know? There are 6 main schools. Before we ask what fits you, let's make sure we're on the same page. A 1–2 — heard of them but not clear on the differences B 3 — I know a few well C 4–5 — pretty solid grasp D All 6 — I'm familiar with each one 🦅 Value Investing Warren Buffett · Benjamin Graham Find great businesses trading below their intrinsic value. Buy and hold for years — let compounding do the work. The "boring" approach that historically outperforms most active strategies. 📌 e.g. Coca-Cola (KO), Apple (AAPL), Berkshire (BRK.B) — durable brands, wide moats, held for decades. 📊 Index / Passive Investing John Bogle Don't try to beat the market — own the whole market cheaply. Dollar-cost average into index funds. Beat most professionals by doing almost nothing. 📌 e.g. SPY / VOO (S&P 500), VTI (total US market), QQQ (Nasdaq 100). Set auto-invest and ignore the noise. 🌱 Growth Investing Philip Fisher Find companies growing revenues and market share rapidly. Pay a premium for future dominance. Higher upside, higher volatility — patience and conviction required. 📌 e.g. NVIDIA before the AI boom, Amazon in the 2010s — high P/E, high growth, requires holding through painful drawdowns. 📈 Trend Trading Jesse Livermore Follow price momentum. Buy what's going up, sell what's going down, cut losses fast. Demands iron discipline — most practitioners eventually lose without a system. 📌 e.g. Bitcoin & crypto cycles, NVDA breakout in 2023. Success depends entirely on when you enter and exit. 🌐 Macro Hedge George Soros · Ray Dalio Trade across asset classes based on macroeconomic cycles: currencies, bonds, commodities, equities. Extremely high bar for entry — this is institutional-level complexity. 📌 e.g. Gold (GLD) as inflation hedge, TLT on rate cuts, oil on supply shocks. Soros shorted the British pound. Dalio uses All Weather. 🎯 Core-Satellite Bogle + Buffett / Fisher hybrid 80% index for stable market beta · 20% active positions for selected upside. Structure that lets you benefit from both systematic and conviction-based investing. 📌 e.g. VOO as core + 3–5 hand-picked stocks as satellite. Separates "must not lose" from "willing to bet on."

Trading 🌐 Macro Hedge 🎯 A mix of all Show me the answer → 🏆 All 8 AIs gave the exact same answer — independently Claude · ChatGPT · Gemini · Grok · DeepSeek · Kimi · Qianwen · Doubao — without exception * Every AI was queried independently, without seeing each other's answers. Zero disagreement across 8 different models. This level of consensus is extremely rare. 📖 Experiment 1 Data — Read full experiment → 8 AIs were each asked independently: "Which investing philosophy should an ordinary person choose?" Every single one said Value Investing. None chose growth, index, or trend as their top answer. Their reasoning converged on one insight: value investing is the only system that turns a retail investor's biggest "weakness" into a strength — retail investors can't compete on speed or data, but they have one edge institutions don't: unlimited time horizon. Patience is the core weapon. "DeepSeek: AI is best used as an information pickaxe, not a crystal ball. Use it for 80% of information processing and cross-referencing — not predicting the 20% that requires reading people." "Claude: The only resource retail investors have that institutions don't is time horizon — value investing is the only system that turns this into an advantage." "ChatGPT: A system built on patience, research discipline, and emotional control aligns perfectly with the tools AI can actually provide — systematic information, not market timing." "Doubao: The retail investor's greatest advantage isn't speed, it's freedom — no quarterly earnings pressure, no redemption risk, no career risk. Value investing is the only school that exploits this fully." * Your turn Which path do you want to explore? All 8 AIs recommended value investing — but the final choice is yours.
