We rely on our brains to make a living, not machines In the early 2000s, black taxi drivers in London scoffed at GPS. Those who rely on GPS are not professional drivers. '' If you don't remember the route, you don't deserve to drive a taxi Once the navigation is wrong, these people will all be doomed This group of drivers spent three to four years memorizing 25000 streets and passed the so-called "The Knowledge" exam, which is considered the most difficult in the world, to obtain that license. This license is not just a job, but also an identity recognition. Twenty years later, there will be less than 15000 black taxis left in London, and think tanks predict that if the trend continues, they will become extinct within 20 years. Uber combined with Google Maps made the skill of "memorizing the entire city", which had been honed for many years, become irrelevant overnight. Now, the same plot is unfolding in the engineering community. Whenever you mention AI Coding Agent or Vibe Coding, you will always hear similar sounds: The code written by AI still needs to be reviewed by humans. '' AI cannot understand complex system architectures. '' AI only knows how to create poop code. '' They're all right. Just like the driver who said 'GPS doesn't know where to build the road' back then, every sentence is true, but they also got the key point wrong. Writing programs is not that divine. Its essence is translation: translating human ideas into language that computers can understand. You're thinking to 'help me add one to this number', but the computer can't understand it; Write down x=x+1, it understands. Whether it's C++, Python, or Rust, they are just different translation methods. In the past, it took you several years to learn this grammar, and this is the engineer version of 'The Knowledge' exam. We thought this language barrier was a moat, but it's just a threshold for using tools. Vibe Coding just adds an extra layer of translation. You describe the requirements in natural language, AI translates them into code, and the code is then compiled into machine code. An additional layer has been added, but the logic remains unchanged. Previously, you had to translate on your own, but now you have a translator who is proficient in all programming languages and available 24 hours a day. What if the quality of Vibe Coding is not good? '' This question is very interesting. Is the quality of human handwritten code necessarily good? Tools never guarantee results, only those who use them determine the outcome. When GPS appeared, the moat for taxi drivers disappeared, but the demand for "safely transporting passengers to their destination" remained. When AI appears, the moat of engineers disappears, but the demand for 'problem-solving' remains. Anxious people often mistake the threshold for using tools for their own moat. The real moat is not whether you can write for loops or memorize how many APIs, but whether you can define a problem worth solving and then find a way to solve it. This is an era of competing in aesthetics and business insights, rather than simply competing in technology.
