I’ve always believed that truly great founding teams tend to have a bit of a rebellious streak—and a distinctive culture of their own.

keep struggling when things come too easy, you don’t exercise the brain nor the emotions. ease can feel like progress, but it often skips the reps that actually change you. growth is usually a loop, not a straight line – you take passes. you try, you fail, you reframe. you come back with a slightly better model, a slightly calmer nervous system, a slightly wider range of what you can handle. hardship isn’t the goal. but friction is gold. it shows you where your understanding is thin, where your habits are brittle, where your ego is doing the steering. the struggle is the curriculum. agents are making things easier, and that’s good. but don’t confuse speed with depth. use AI to remove busywork, then spend the saved energy on the parts that still hurt a little: the unclear problem, the uncomfortable conversation, the hard tradeoffs, the things you can’t yet explain in words. instead of putting all your wishes into the black box, actually keep thinking, and seeing things fully. keep the difficulty where it matters. outsource the tedious, keep the meaningful resistance. that’s how we keep learning – and how we stay human while your tools get superhuman.

「馒头趁热吃」第一期预告来啦~ 既然是第一期,本人打算搞个有奖问答,200美金评论区抽5个宝子👇 1/ 第一次被Open Claw 震撼到的Moment 是什么时候? 2/ 当AI 允许那么多人直接跳过了学习 Coding 这一步,这到底是捷径?还是陷阱? 3/ 你觉得你的工作距离被Agent 接管还有几个月? 主打一个一起来聊聊天 😉

I don’t think the US is ready for what’s happening in China I flew to Shenzhen to speak about ROSClaw at an @openclaw meetup 500+ ppl capped 1000+ waitlist That’s not a “meetup” THAT IS CONFERENCE SIZE Many call OpenClaw hype, but on the ground, it’s a full blown movement

半年前跟 @Christianeth 喝咖啡 他说 @0xinfini 刚迭代了一批新团队 所有工程师必须大部分代码用ai写 即使是老手 一个月内还不用的 就可以走了 因为明显不属于这个时代 我大为震撼 因为那会我都没用过Cursor 说来惭愧 也为他员工庆幸 在这个时代 有个这样有格局的老板 绝对三生有幸 直到去年秋天 在北京和一个bro见面 我们常一起蹦迪喝酒的 他被尊称为"睡在工体的男人" 他说新公司的代码 他用codex贡献1/3 我一看产品 质量非常能打 他亲手带我用codex写了个demo 说是走进魔法学院 毫不为过 从那开始 我才真正意识到 未来会用ai是个必选项 很多人说openclaw太难用了 安装也麻烦 学习门槛也高 等成熟了再用 我感觉真正的意义 是学习使用的过程 和构建整个Mindset 就像19年如果没有玩Eos Dapp 那想必 2020年的Defi Summer 2021年的NFT狙击 只能吃个鱼尾 重要的不是当下有多少用 而是已经选择站在了新世界

Doug DeMuro ranked the @Tesla Model S as the #1 most important car of the last 30 years in his new video. Doug: "The Model S really changed the world. It made you think that EVs could be cool, fast, luxurious. It really reset any public opinion about EVs, that you didn't have to make major compromises; They (Tesla) created a cultural icon. If you created a list of the top 10 all-time cars that changed the world, Model S is in the top 5."

Totally agree! So far, AI’s only downside is that it forces me to keep learning—leaving me no time to play games. 🤣

Marc Andreessen explains why AI coding won't replace programmers, but fundamentally change what they do. He argues that AI coding is just the latest abstraction layer, and the job of a programmer has always evolved with each one. Andreessen's key reframe of what's actually happening: "AI coding actually abstracts away the process of actually writing the scripting code... This is the next layer of the task redefinition under the job of programmer." He's clear that the best programmers aren't being replaced. They're already adapting, even if their day-to-day looks radically different now. Their job has shifted from writing code line by line to managing dozens of AI agents working in parallel. "The world's best programmers today will tell you, 'My job is I'm sitting there and I'm orchestrating 10 code bots running in parallel.' Their day job now is kind of arguing with the AI bots to try to get them to write the right code." But @pmarca is adamant this doesn't make foundational knowledge obsolete — it makes it more important. "You need to still fully understand and learn how to write and understand code, because if it doesn't work or it's not doing what you expect, you need to be able to understand the results of what the AI is giving you." He draws a direct parallel: Just as someone writing scripting languages still needs to understand how a microprocessor works, someone orchestrating AI bots needs to understand the code those bots produce. "It's this upleveling of capability where you actually want the depth to go down and understand what the thing is actually doing, even if you're not spending your day doing that by hand." The result, in his view, is transformative: "Now programmers are going to be 10 times or 100 times or a thousand times more productive. And that is overwhelmingly a good thing." The pattern: New abstraction layer emerges → tasks change → the job gets redefined upward → productivity explodes It raises a question every programmer should be sitting with... Are you building the depth to evaluate what AI gives you, or just accepting the output?

Here's my conversation with Peter Steinberger (@steipete), creator of OpenClaw, an open-source AI agent that has taken the Internet by storm, with now over 180,000 stars on GitHub. This was a truly mind-blowing, inspiring, and fun conversation! It's here on X in full and is up everywhere else (see comment).
