This may have an impact on the development of some simple chat applications, but it will not cause the bottom programmers to lose their jobs.

Secondly, ChatGPT itself needs programmers to develop and maintain. Its appearance may have an impact on some artificial intelligence programmers, but it will also bring them new job opportunities.

Generally speaking, the appearance of ChatGPT will improve the automation level of chat applications, but it will not lead to the unemployment of bottom-level programmers.
