Today's Note



I saw a tweet from @BaibanbaoNet:

Recently, the development of AI has slowed down, OpenAI is frequently banning accounts, and GPT-4 is unstable. Without the excitement of "industrial revolution every day, cultural renaissance every night," we can take the time to think about what GPT can do for our own fields. There is no doubt that the roadmap is already clear: AI + Python + professional know-how = your future.

This formula is interesting: $Your Future = AI + Python + Professional Know-How$.

With the release of ChatGPT, discussions about AI are endless. It can be foreseen that in the future, AI tools like ChatGPT will become popular and will have a huge impact on human production methods and modes. Thinking back to the news a few days ago, Goldman Sachs' report states that 300 million jobs worldwide will be replaced by AI. If this prediction by Goldman Sachs is true, human society is likely to undergo tremendous changes.

I have doubts about the need for Python skills, but having coding skills is definitely a plus. Coding is essentially one of the concrete manifestations. Being able to write and write good prompts is a coding skill.

Professional know-how is necessary and crucial, it is the prerequisite for using AI well. Without professional know-how, blindly believing in and relying on answers that are made up and fabricated will mislead oneself and others. As I mentioned in a previous newsletter:

AI will not replace humans, but it will replace those who do not know how to use AI, and it will also replace those who only know how to use AI.

The "how" seems to be becoming less important in the AI era. When you don't know what to do, you can just ask AI directly. However, will this bring about some kind of regression?

I think the formula might be better like this: $Your Future = AI + Coding + Professional Literacy - 1/2 Hands-on Ability$


The day before yesterday, when I was writing a script, Zeze said that the second trial of the Chongqing brother and sister falling case was being live-streamed. Yesterday at noon, I saw the news that the court announced the adjournment of the verdict.

Shouldn't scum like this be dealt with on the spot? Even tigers do not eat their own cubs, so what reason does the man who killed his own children have to survive? And that third party, within 5 months, there were over 17,000 chat records discussing how to kill, an average of 113 messages per day, an average of 4.7 messages per hour, all discussing murder!!! Such madness, such disregard for human relationships!!!

In the second trial of the Jiang Ge case last year, the judgment of the first trial was upheld, and there was a paragraph in the judgment of the first trial:

Assisting the needy and helping the poor is a traditional virtue of the Chinese nation, and honesty and friendliness are important contents of the core socialist values. Judicial judgments should guard the bottom line of social morality, promote virtuous deeds, and guide the whole society to respect virtues and do good deeds.

I hope that the verdict of the second trial of the Chongqing brother and sister falling case can continue to uphold the bottom line of social morality.


When it comes to knowledge management, it is easy to fall into two traps. One trap is wanting to build a perfect note-taking system from the beginning, and the other trap is constantly trying out note-taking software.

Everyone's note-taking system is different, just like no two leaves are exactly the same. Because note-taking systems are very personal, what to record, how to record, depends entirely on the individual. And people are fickle, cycling between progress and regression. This also means that a perfect note-taking system simply does not exist. It can approach perfection indefinitely, but it will never be perfect.

After falling into the misconception of building a perfect note-taking system, it is natural to constantly try out note-taking software, especially considering the variety of note-taking software available now. Although "sharpening the knife does not delay the cutting of firewood," just sharpening the knife without cutting firewood is useless.

In Why Write Notes, The Double-edged Sword of Trying Out Note-Taking Software, and The Importance of Note-Taking in the AI Era, I have repeatedly emphasized that writing notes helps us grow, think, and improve. It provides support for our output. This is the essence. As for what the note-taking system looks like, what the note-taking software looks like, those are the details. The essence must be grasped before the details.


Today, my colleague was playing Duolingo, so I opened the Duolingo app that had been gathering dust. Unexpectedly, something stupid happened. There was a question asking me to translate "How do you pronounce this word?" and I answered with "How do you pronounce this word?" But it turned out to be wrong, and I had to write "How do you say this word?" It's so stupid, I can't stand it anymore, so I uninstalled it 🤬

I've been annoyed by Duolingo's stupid answers several times before, so I basically haven't used it much. I don't understand why so many people praise it. Are they getting paid? Or are they just English beginners?

Speaking of learning English, I found that if I can watch two episodes of a TV show every day, about two hours in total, my sense of language and my listening and speaking skills will improve. Maybe it creates a language atmosphere, and if my mind follows the plot of the TV show, it's easier to switch to English thinking.

Another way of learning English that I found on Twitter is summarized by @arui_kisi. He gave two reasons for reading product documentation:

The product itself is being used and the documentation is accompanied by pictures. Sometimes you can understand what is being described without even reading the words, making it easier to guess the meaning of the words.

The wording in the documentation is concise, without complex vocabulary, making it more suitable for learning.


I have been in Fuyang for over a week. These past two days, I went out for a walk, but I found that there are very few people in the shopping malls in Fuyang, and there are not many stores open. This makes me feel very strange. So I looked it up on Baidu Baike and found that Fuyang's GDP in 2022 exceeded 30 million, which is similar to cities of this scale that I have been to, and I didn't feel that there were few people or stores. Could it be because the population distribution in Fuyang is uneven, with relatively low population density in many areas?

When I took a taxi, I chatted with the driver. According to the driver, Fuyang doesn't have much industry. Although there are many registered residents, there are few permanent residents, and most people work in Zhejiang and Guangdong, resulting in a serious population outflow. I'm not sure if what he said is true, but it's probably close. After all, besides the lack of people in the shopping malls, there really aren't many people on the streets.

In addition, I also found that there are really few restaurants in Fuyang. These days, when I order takeout, I have tried several different restaurants, but it's always the same few dishes. Even in a food desert like Beijing, you can order takeout without repeating the same dish for a week. But here, it seems that no matter which restaurant you order from, it's always the same few dishes. Perhaps this is because the local people have relatively simple tastes? Or maybe it's because the variety of dishes offered by the restaurants providing takeout is not rich enough?

Fortunately, there are only a few more days left. If I hold on for another week, I can go to Wuhan to eat the super delicious and special hot dry noodles.
