A complete collection of slogans on factory walls in the 1980s.

Everyone can usually see some slogans on the wall on the road. In the past, I always thought that these slogans were printed with spray paint, but until the network became more and more smooth, someone released a video on how to write slogans on the wall. I found that those slogans that looked like printing were actually written by people. At that time, I felt that these people who wrote slogans were really amazing, and they wrote better than printed ones. It stands to reason that at present, printing can completely replace handwritten wall characters, but handwritten wall characters have always existed, because those who write strong body characters are completely skilled, and they write quickly and in one go, which is shorter than printing, and the printed characters are better, and the printed characters are too rigid and not as flexible as those written by people, so people still like handwritten wall characters, even though technology is developing.

In fact, it's hard for you to imagine how to use handwritten wall characters, because it feels completely different on paper and there is no chance to do it again, so you can only do it at one go. If you want to repair it, it is very difficult, so it is likely that practice makes perfect. If you write on the wall for a long time, you will become very skilled, and we usually do the same when we do our own work. Once you have done it for a long time, you will be very familiar with it.

This incident also tells everyone that even though the current technology can do many things, there are still many things that can only be done manually. There is no substitute for technology. Now many people are worried that artificial intelligence is getting worse and worse. Will someone's job be replaced? In order to be responsible, some people's jobs will be replaced The work of these replaced people is often mechanical and can be completely replaced by robots without brains. As for those professions that need brains and are highly flexible, don't worry. For example, mainframe programming will not be replaced, so if you want your career to be replaced, you should study a good major and be a person who uses brains every day.

Now, some people have come to buy robots instead of labor, just like those express delivery companies, they have bought robots for sorting and express delivery. Robots can work 24 hours a day without rest, so in general, robots are much more cost-effective than manual work. So with the development of the times, such as these sorting and express delivery, the fixed work on the assembly line in the factory, this relatively rigid work, without any flexible workstation, will definitely be replaced by robots, so everyone should pay close attention to learning a technology.
