Affected by machine substitution, low-tech blue-collar jobs will disappear one by one. As the pace of transformation and upgrading of various industries has accelerated in recent years, more and more industries have begun to explore machine substitution. The first impact of machine substitution is low-tech blue-collar jobs. Although it is a simple and repetitive work, it requires a lot of manual participation. The automatic locking screw machine can save 4-5 screw-twisting employees for the enterprise, and only one person can take care of the automatic equipment. If a workshop has 50 employees doing the screw-driving process, only 10 people can complete the process, and the remaining 40 people will face unemployment or job transfer. 

At present, most manufacturing enterprises tend to be semi-automated or low-cost automation, and the production line still needs a certain amount of labor. It has not yet entered the stage where the machine replaces the human, but the replacement of the machine is a development trend, and it will come sooner or later. The existing low-tech jobs will gradually decrease or even disappear in the future, and fully automated equipment will be used for production. The impact on blue-collar workers is profound.

In addition to technical reasons, difficulties in recruitment and management are also important driving factors for the substitution of enterprise machines. More and more post-90s enter the labor market, posing higher challenges to enterprise management. The concept of many post-90s generations is that "work is a part of life", which is very different from the concept of "coming out is to work and earn money" of the previous generation. The lower the technical content, the higher the requirements for the proficiency and repetition of the same action, the more boring the work in the corresponding position, and the higher the turnover rate. Further automation of production can alleviate or even solve this problem.
