In the past two days, I read a post on the forum, which mentioned a sentence: “If you can’t afford a Mac and can’t go to the United States, you won’t be able to afford a Mac and can’t go to the United States in the future. Naturally, you can only rely on the information on the Internet to construct your own perception, and the probability is that you will choose your favorite information to construct. If your source of information is just wrong, the more you think about it, the more wrong it gets.”

Some people at the bottom chimed in, but it was more of a grimace.

After I read that, I knew what the owner was talking about, but he really didn’t express himself very well. I’m going to expand on it here as a topic essay.

In the Internet era, we seem to be accustomed to open the phone, brush this, brush that, thanks to the growing maturity of the recommendation algorithm, each App has a belong to your own “matrix”, that is, “user profile”. Learned linear algebra should know that each matrix has its own characteristic matrix, yes, this is the core of the recommendation algorithm.

So these “matrices” are like a digital cage, the phone in front of you trapped at the same time you do not know. Going back to the beginning, what I’m saying is that a lot of people spout off about Macs and Windows, but those people don’t even buy one and put it to the test themselves, they just get their “thoughts” through the information cocoon, and when they see a comment that agrees with their own, they just slide on by, ignoring all the other comments that don’t agree with their own. He sees a comment that agrees with him and slides away, ignoring all the other comments that don’t agree with him.

There is a lot of talk on the internet about “RUN”, but when I talk to people who have lived in the US in real life, I realize that the US isn’t that great, and China isn’t that bad either. Recently, when the company has the opportunity to transfer to other countries, many people become reluctant, because they have to start to consider the foreign wages, taxes, housing prices, convenience, the difference between status and no status, how long it takes to get the status and other factors, when they consider all of this they will feel as if the country is a little better. And how many of those who advocate for “RUN” will open Zillow and look at the prices in San Francisco and Vancouver?

Another example, before the Tencent, performance is divided into five grades, in the pulse or the company’s internal forums, we all think that four or five stars is good, most of the three-star, two-star should leave, but when I left before talking to the head of the team to know, the director of the evaluation of the performance of young people who often work hard overtime four or five-star and the general end of the year award to their own true lineage three-star and lucrative end of the year. The reason is that young people like the surface of things, and old people like real, only these old people lineage can solidify the director’s position, overtime people take four or five stars can make everyone more “volume”, of course, provided that these people’s own ability is not bad. However, this fact is often no one will tell you, more often than not, your side and you take the same three-star people will hypocritically cooperate with you to complain about injustice, together with those who take the four-star people with what, but they will never tell you his real end-of-year awards figures.

These two examples are more or less around the statistics, but at least it also illustrates a point, you want to find useful information from the Internet, is tantamount to gold in the sand, good luck panning, bad luck wasted a lot of time, if you even go to and other people to reason, it will only make the number of prison to trap you more and more tight.

Recently ChatGPT is very hot, everyone thinks it is “revolutionary”. But in my humble opinion, it’s just a chatbot, only with better ability to collect and summarize information, more applicable scenarios, and most importantly, it can’t think independently. I’m rather pessimistic, I think this bottleneck still can’t be broken in the foreseeable future, Yoshua Bengio The old man may have to pass away with regret.

So yeah, we humans still have the privilege of thinking. Put down your phone, read the sages’ books, and get a good night’s sleep.
