Everyone can usually see some slogans on the wall on the road. I used to think that these slogans were printed or sprayed with spray paint, but until the network became more and more smooth, someone posted a video on the wall on how to write slogans. I found that those slogans that looked like printing were actually written by people. At that time, I thought these people who wrote slogans were really amazing, and they wrote better than printed ones. It stands to reason that printing can completely replace calligraphy on the wall now, but calligraphy on the wall has always existed, because people who write Zhuang characters are completely skilled, writing quickly and in one go, which is shorter than printing, and the words printed by printing are better, and the words printed by printing are too rigid and not as flexible as people's writing, so people still like calligraphy on the wall, even though technology is developing.

In fact, it's hard to imagine how you can write wall characters, because the feeling of writing wall characters on paper is completely different. There is no chance to do it again, so you can only do it in one go, and it's difficult to repair it. Practice makes perfect. Writing on the wall will become very skilled after a long time, and so will we usually do our own work. Once you do it for a long time, you will be very familiar with you.

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? 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 have high flexibility, don't worry. For example, mainframe programming will not be replaced, so if you want your profession not to be replaced, you should learn your major well and be a person who uses your brain every day.

Now some people buy robots instead of labor, just like those courier companies, they buy robots to sort and express. Robots can work 24 hours a day, so in general, robots are much more cost-effective than manual work. Therefore, with the development of the times, such as sorting and express delivery, the fixed work on the assembly line in the factory is relatively rigid, and it does not need any flexible workstations, so it will definitely be replaced by robots, so everyone should pay close attention to learning a technology.
