埃隆·马斯克

问：SpaceX是如何用第一性原理把火箭发射成本降低90%的？ Q: How did SpaceX reduce rocket launch costs by 90% using first principles?

答：马斯克第一性原理应用：

1️⃣ 分解问题："火箭是用什么做的？材料的真实成本是多少？"
2️⃣ 打破假设：火箭为什么是一次性的？飞机不是也能重复使用吗？
3️⃣ 垂直整合：内部制造所有零部件，不依赖传统供应商
4️⃣ 快速迭代：测试、失败、学习、重试——而不是等待完美方案 A: Apply Musk's first principles:

1️⃣ Decompose: "What are rockets made of? What do the materials actually cost?"
2️⃣ Break assumptions: Why should rockets be expendable? Planes are reusable, aren't they?
3️⃣ Vertical integration: Build everything in-house, don't rely on traditional suppliers
4️⃣ Rapid iteration: Test, fail, learn, retry — instead of waiting for a perfect solution

问：面对一个臃肿的产品，如何用马斯克的五步法重新思考？ Q: Facing a bloated product, how to rethink using Musk's 5-step process?

答：五步法简化框架：

1️⃣ 质疑：这个功能/流程是谁发明的？为什么需要它？如果没有会怎样？
2️⃣ 删除：把不必要的东西删掉——最强的操作是删除
3️⃣ 简化：剩下的东西能不能更简单？
4️⃣ 加速：让必要的部分跑得更快
5️⃣ 自动化：只有在1-4步完成后才考虑自动化 A: Apply 5-step simplification framework:

1️⃣ Question: Who invented this feature/process? Why is it needed? What if it didn't exist?
2️⃣ Delete: Remove unnecessary things — the most powerful operation is deletion
3️⃣ Simplify: Can the remaining things be simpler?
4️⃣ Accelerate: Make essential parts faster
5️⃣ Automate: Only consider automation after steps 1-4 are complete
