Why do many people recruit CAD now? There is no requirement for academic qualifications, and it is simple and the salary is good. Who can help me analyze it?

I think I'm looking for a draftsman. This kind of work is very hard. You can't get much money by painstaking efforts, and there is no possibility of promotion in the future. Migrant workers sitting in the office. You can do it for a while, but don't make long-term plans. Use your spare time to learn some professional knowledge and think more about the future. You can't paint forever. I can't draw when I'm older, but my skills are completely different. Many technicians are more valuable as they get older.
