一个Youtube视频总结工具和一些思考

我发现最近几年视频正在取代文字成为主要的获取信息的渠道随着视频制作的门槛越来越低估计未来绝大部分内容都会来自视频但是高效地获取视频内容是一件比较困难的事情因为时间轴的限制无法像文字那样被快速浏览反复回看总结

而且比起文章来视频更能分散注意力使得我们不断地在视频标题之间横跳我们其实是在信息的海洋里漂流瓶被动地接受很多信息如果有一个工具在我们和视频本身之间做一个缓冲可以让我们拿会对信息的主动权

所以一直想做这么一个可以总结Youtube视频的工具最近终于借助AI for coding的力量在Cursor的帮助下实现了产品还是demo的状态安装和使用需要一些终端的知识依照文末的Github链接中的说明就可以运行

2024年的一些总结

这篇总结躺在草稿箱里一个多月断断续续地编辑今天终于能发出来
2024年经历了一个重要的事业转折点这一年大部分的时间是与自己相处跳出了以前的框架想明白了很多事情也许明白只是假象以下是部分罗列

  • 人生是一场游戏人们为自己的人生旅途中赋予了很多意义但其实人生的意义只在于体验游戏让人上瘾因为它们都有一个共同点快速的正反馈可以把人生大小小的困难设计成游戏分解目标建立正反馈系统

强化学习和人工智能的奇点

Andre Karpathy近日在X平台上也对R1作了评价评价本身不重要重要的是他引申出了一个更加深刻的观点即AI的自我进化可能远超我们想象这个观点让人细思极恐

他提出合成数据和强化学习是等价的在强化学习的试错过程中每一次试验本质上都是模型生成的合成数据而它随后根据奖励函数来进行学习反过来说当你对合成数据进行筛选和排名时这个过程实际上就是一个0-1奖励函数可见数据很大程度上是算力下游的产物

互联网极简史

最早畅想互联网的人是谁大部分美国人同意是万尼瓦尔他在诚如所思中的描述是人类对互联网的最早的想象其它版本众说风云但也都指向了20世纪初

未来的作者是否不再使用手写或打字的方式而是直接对着记录机讲话就可以了呢他会通过速记员或者一个大圆桶间接地去做这件事如果他想直接录入一条键入的记录所需的东西都是现成的他需要做的就是充分利用现有装置并转换他的语言

—— 万尼瓦尔.布什 诚如所思1945

互联网真正的开端大概在1960年仍然比大部分人想象得要早得多它起于军方后扩展至大学最后完全商业化花了近30年时间而之后的30年是互联网飞黄腾达的30年前前后后60年历史长河中的一瞬

OpenAI-o1真的会思考吗

在OpenAI的眼中实现通用人工智能大致要经历5个阶段对话(conversation)推理(reasoning)代理(agent)创新(innovation)组织(organization)OpenAI的o1模型已经达到了推理这一阶段相信第三阶段也指日可待在它到达第四阶段—创新—之前个人认为还需要达到直觉这个阶段

OpenAI在上周推出了最新的模型o1-preview名字的含义是Orion猎户座一代有人说计数器重置为1因此很可能不会有GPT-5o1将开启一个全新的时代
很多人对o1模型能力进行了解读也有大量的新奇的应用如雨后春笋一般涌现出来总得来说o1是思维链(Chain of Thought, COT)的集大成者它很可能推动LLM新一轮的范式改变侧重点从训练到推理转移然后以推理时间的增长来继续scaling law但是它真的会思考

李沐:语言模型的现状与未来

AI大牛李沐最近回到上海交通大学做了一次演讲聊了聊语言模型的现状和未来趋势李沐的观察很有启发不愧是这个站在这个领域最前沿的人他说现在的AI基本可以完成文科白领的大部分工作但是要完成复杂任务和与真实世界交互还有很长的路要走而制约大模型发展的瓶颈主要是内存电力数据其中数据的重要性在演讲中反复被强调

李沐最后还给交大学子们指点人生迷津他说创业就像是当海盗天天看着市面上什么好的机会一旦发现就all-in抢到了就爽一把没有抢到就死掉了相比起在大公司里上班和读博深造创业对动机motivation的要求是最高的你内心深处要有那么一件十分想去做不去做就抓耳挠腮就会后悔的事情这个事情要满足你最深层次的欲望你还要能抗得住一次次的打击在别人都不看好的时候坚持走你选择的路创业就是要笃定就是要让自己的内心强大到混蛋

以下是李沐演讲中关于技术方面的总结

AI is electricity in late 1800s

Formal Google CEO Eric Schmidt has stirred quite a bit of controversy with his comments on Google’s work life balance, the Ukraine War, and startups strategy on pursuing growth. Putting those aside, what resonated with me was a concept brought up by the host Erik Brynjolfsson, that is general purpose technology. He said general purpose technologies are powerful because they ignite other complimentary innovations, but it usually takes process innovation or organizational innovation to fully unleash that power.

He used electricity as an example. When electricity was first introduced into factories, they didn’t become significantly more productive than the factories that were powered by steam engines.

Patrick Collison's latest interview on Jensen Huang

“I’d rather torture you into greatness than firing you.” —- Jensen Huang

On April 24th, Patrick Collison, CEO of Stripe, interviewed Jensen Huang, who is the CEO of Nvidia. Below are the main takeaways:

No One-on-One Meetings. Jensen has 60 directors who report to him, but he prefers not to have one-on-one meetings. By having all 60 directors together at once, he has eliminated at least 7 layers from the company’s structure. He believes it is more effective to communicate with all stakeholders simultaneously, allowing information to flow more efficiently among people. Everyone can contribute to and share in the information flow. Feedback is learning. Not only do you work to solve the problem at hand, but you also create conditions for others to learn from your situation. On the other hand, isn’t it a great opportunity to learn from other people’s mistakes, disasters, and strategies?

The Art of Strategy: Lessons learned from Go

Go, the ancient board game originating from China, is not merely a game of skill but a profound exploration of strategy and decision-making. Its core concepts—such as Big Points, Frameworks, Influence, and Initiative—not only guide players to victory but also serve as metaphors for navigating life’s complexities. These principles offer invaluable insights into making better choices, anticipating outcomes, and achieving long-term success.

In Go, Big Points refer to key strategic areas on the board that yield the greatest potential gains. These points are often the first moves in a game and set the tone for future developments. Ignoring these points can lead to missed opportunities or allow opponents to gain a decisive advantage. Similarly, in life, identifying and prioritizing high-impact opportunities is essential. For example, an entrepreneur might focus on entering a fast-growing market rather than investing resources in smaller ventures. Recognizing the big points in life helps allocate energy effectively, ensuring meaningful progress.
