就像短视频和碎片化信息会削弱人类的注意力一样,垃圾数据也教会了 AI 模型“偷懒”,放弃思考!这两天 X 上很火的一篇论文 LLMS CAN GET "BRAIN ROT",用 X 的社交内容,验证了语言模型也会得“大脑腐烂”🧠
“大脑腐烂”在 2024 年被牛津大学出��社评为年度词汇,这是一种因沉迷互联网,大量消费低质内容,而对我们认知产生伤害的现象。研究者从第一性原理出发,将“垃圾数据”定义为那些“能够以琐碎的方式最大化用户参与度的内容”,他们从两个维度在 X 上筛选这些内容:
1. 短小 (长度 < 30个token) 且高热度 (点赞、转发、回复等 > 500次) 的帖子,利用了社交平台推荐算法的核心逻辑;
2. 包含阴谋论、夸大其词、标题党、虚假信息或肤浅的生活方式炫耀等内容;
通过喂给 AI 模型这些“垃圾内容”,实验显示它们会系统性地损害模型,导致其认知能力下降 。最核心的伤害机制是,模型学会了一种叫做“思维跳跃”(thought-skipping)的坏习惯 。就像它所学习的垃圾内容一样,模型开始放弃深度、连贯的思考,倾向于给出简短、未经推理的答案 。
这最终导致了模型在推理、长文理解和安全方面的能力全面衰退,甚至催生出如自恋和精神变态等负面人格特质 。并且这种伤害是持久的,即使之后用大量干净数据也难以完全修复 。。。
这篇论文不仅揭示了 AI 模型的一种新型脆弱性,更像是一面镜子,照见了人类自身在当前信息环境下面临的认知挑战。“精神食粮”的质量决定了认知能力的健康水平,这一点,对人类和 AI 同样适用🤔
Nvidia, Microsoft, BlackRock, and Elon Musk’s xAI are joining a consortium to buy Aligned Data Centers for $40 billion—the largest data-center deal ever.
Aligned, owned by Macquarie Asset Management, operates sites across the Americas.
The purchase is the first investment of the Artificial Intelligence Infrastructure Partnership (AIP), formed in 2024 by BlackRock, MGX, Microsoft, and Nvidia to fund AI infrastructure, with Kuwait’s KIA, xAI, and Temasek later joining.
AIP plans to deploy $30 billion in equity capital.
Announcing my new course: Agentic AI!
Building AI agents is one of the most in-demand skills in the job market. This course, available now at https://t.co/zGHUh1loPO, teaches you how.
You'll learn to implement four key agentic design patterns:
- Reflection, in which an agent examines its own output and figures out how to improve it
- Tool use, in which an LLM-driven application decides which functions to call to carry out web search, access calendars, send email, write code, etc.
- Planning, where you'll use an LLM to decide how to break down a task into sub-tasks for execution, and
- Multi-agent collaboration, in which you build multiple specialized agents — much like how a company might hire multiple employees — to perform a complex task
You'll also learn to take a complex application and systematically decompose it into a sequence of tasks to implement using these design patterns.
But here's what I think is the most important part of this course: Having worked with many teams on AI agents, I've found that the single biggest predictor of whether someone executes well is their ability to drive a disciplined process for evals and error analysis. In this course, you'll learn how to do this, so you can efficiently home in on which components to improve in a complex agentic workflow. Instead of guessing what to work on, you'll let evals data guide you. This will put you significantly ahead of the game compared to the vast majority of teams building agents.
Together, we'll build a deep research agent that searches, synthesizes, and reports, using all of these agentic design patterns and best practices.
This self-paced course is taught in a vendor neutral way, using raw Python - without hiding details in a framework. You'll see how each step works, and learn the core concepts that you can then implement using any popular agentic AI framework, or using no framework. The only prerequisite is familiarity with Python, though knowing a bit about LLMs helps.
Come join me, and let's build some agentic AI systems!

The Core Principle: Defense First
For 30 consecutive years, I've maintained a never-decreasing net worth. Somehow, each year I figured out a way to make net progress. And I can tell you that it wasn't by always hitting home runs. It was by rarely striking out in a catastrophic way. Most people think wealth-building is about the big score. When in reality, it’s about minimizing drawdowns, consistently chipping up, and occasionally making a big score. By keeping losses small when you’re wrong, you make it far easier to climb back and set new highs. And by consistently making progress, you always keep your capital in tact ready for opportunities. The secret is to compound capital, not mistakes.
