Four Stages for developers

(1) A hacker who understands a certain technologyProgramEmployees in the army belong to cheap labor and are at the bottom of the pyramid;

(2) The technology "why" can be further understood, which is relatively less, and belongs to the second layer of the pyramid;

(3) After understanding a technology, there will be fewer optimizations and improvements to the existing technology, which belongs to the third layer of the pyramid;

(4) What type of person is the fourth layer of the pyramid? What I have defined is those who have a deep understanding of multiple technologies. When providing integrated solutions, people who know how to choose and match various technologies and who can optimize and improve their existing matching schemes are the "sweet cakes" in enterprises".

The value or core competitiveness of technicians is ultimately determined by the essential needs of enterprises (markets ).Provide reliable integrated solutions at the fastest speedInstead of watching whose technology is cool or trendy
