AI Master Karpathy's AI Note-taking Workflow, Ordinary People Can Achieve 80%
I almost never use note-taking software myself. As someone who isn't particularly clever, the app I use most often is Apple Notes. However, I felt this master's note-taking workflow was quite worth a try because it actually resembles my current AI workflow—somewhere between having notes and having none (?). Generally speaking, the way most people use ChatGPT is like buying things at a convenience store: you have a question, you ask it, you get an answer, you close the window, and next time you start from scratch. What Karpathy and Lex Fridman do is completely different. They have AI build a library for them, and this library grows on its own. This article will break down how these two top figures in the AI field take notes using AI, and then tell you: without writing any code, you can achieve 80% of what they do.
First, understand one thing: the way you use AI might be a constant waste. Imagine you have two interns on hand, with completely different ways of working. Intern A, every time you throw a question at him, he loses his memory after answering; next time you ask a similar question, he searches from scratch again. Intern...

Company as Agent: Block Proposes the Most Radical Organizational Structure in Management History
On March 31, 2026, Sequoia Capital partner Roelof Botha and Block founder Jack Dorsey co-published a ten-thousand-word essay titled 'From Hierarchy to Intelligence'. The article references Roman legions, the Prussian general staff system, and the Manhattan Project, with only one core argument: AI can replace the only large-scale coordination mechanism humanity has used for two thousand years, namely hierarchical management. Sequoia partners usually publish market trend reports or investment memos, not organizational management essays. Botha taking the field himself and putting his name alongside Dorsey's signifies that Sequoia believes the importance of this matter transcends a single company's internal restructuring. But the timing is very subtle; Block just laid off about 40% of its employees, roughly four thousand people, in February 2026.

Anthropic Design Head Jenny: Every Monday at 10 AM, AI Has Prepared Three Product Directions for Me
Last month, I wrote an interview analysis of Anthropic Design Head Jenny Wen. In Berlin, she told a room full of designers, 'The design process is dead.' Looking back at that speech three months later, I feel the content is already outdated. That article was about philosophy: whether your professional skills are still valuable in the AI era. This one is about implementation. Jenny recently appeared on Peter Yang's Podcast. This time, she didn't talk about whether the design process is dead or not; instead, she directly shared her screen to demonstrate: after the process died, how exactly does she work every day? Every Monday at 10 AM, her computer automatically generates a presentation containing three validated product directions, complete with wireframes and priority recommendations. She doesn't need to hold any meetings or manually organize any data; all of this is completed in the background by Claude Cowork's scheduled tasks. Jenny Wen is currently the head of Cowork design at Anthropic, having previously led the design teams for FigJam and Slides at Figma. This episode 40...
