年轻程序员，不要去生活成本低的地方 复利，已经被讲烂了。但还要提。 一个城市，生活成本低，说明收入水平也低。别抬杠，抬就是你对。 收入低，也就意味着，你复利积累的起点低。十几年后，资产积累差距，跟高薪城市就会显著拉开。 相反，等资产增值的速度，远超工资收入，再去生活成本低的城市，不迟。 这也是为什么，美国有几个专门的养老州。

A 16 year old in China brought a breadboard to his school science fair. His teacher asked him to explain how the circuit works. He said: I don't know, I just told Claude Code what I wanted and it built everything for me. The teacher gave him a zero for not understanding his own project. The next week that same teacher was caught using the exact same tool to prepare circuits for his other classes. The kid had never touched a breadboard before that week. Watched one YouTube video about ESP32 chips, opened Claude Code and described what he wanted in plain Chinese: make a button that turns on a light and show me everything I need to build it. Claude Code came back with three things. A full 3D model of the circuit showing exactly where every wire goes. A 2D schematic with every pin mapped. And the firmware ready to flash. Build. Flash. Monitor. Three buttons on screen. Zero errors. He bought the parts for $6 at an electronics market near his school. Plugged the wires where the 3D model told him. Pressed the button on the breadboard. The LED turned on. Terminal logs scrolling: button pressed, LED on. Released. LED off. Over and over. Working perfectly. He filmed an 8 second clip of his hand pressing the button, the LED glowing orange, and the terminal confirming every press in real time. Posted it the night before the science fair thinking nothing of it. The science fair was the next morning. He set up the breadboard on a table between a volcano model and a solar system poster. The judges walked over. Asked him to explain the circuit. He pointed at the 3D model on his laptop and said Claude Code designed it. They asked what GPIO means. He said I don't know. They asked what a resistor does. He said I don't know. They asked why the LED turns on when he presses the button. He said because Claude Code told it to. Zero points. The judges wrote: student does not understand the fundamentals of his own project. He went home. Didn't care about the grade. The clip he posted the night before had 340,000 views by the time he got back. Hardware engineers in the comments were losing their minds. One professor wrote: I teach a 16 week course on embedded systems. This kid just did weeks 1 through 12 in one prompt. A senior engineer in Shenzhen tested the same approach on a 14 component sensor array with I2C communication. Described it in English. Got a working design in 3 minutes. Said his team would need 2 days. The kid doesn't know what GPIO stands for, doesn't know what I2C means, can't tell you the difference between a resistor and a capacitor. He just said make a button that turns on a light and Claude Code handled the rest. Then the part nobody expected. His CS teacher who gave him the zero was seen the following week using the same tool to design circuits for his grade 11 and grade 12 classes. A student from grade 12 recognized the Claude Code interface on the teacher's laptop during class and posted about it. The screenshot spread through the school group chat in an hour. The teacher who gave him a zero for using Claude Code was using Claude Code himself to prepare lessons he couldn't build without it. The kid saw the screenshot that evening. Didn't say anything. Didn't post about it. Just smiled and went back to his laptop. 340,000 views. Zero points at the science fair. One teacher who punished a student for using the same tool he uses every night. The LED is still glowing on his desk. The breadboard is still wired. The grade is still a zero. And the teacher still hasn't apologized. He doesn't need the grade. 340,000 people already graded his project. They gave it an A.
