If you are a programmer and needs to solve issues and bugs... you can't just cut and paste... you need to understand the program, the flow of information  and debug the issue. But sadly a lot of half passed six 'programmers' out there that also just cut and paste without understanding the underlying process and when issues cropped up and they could not solved it, they just shift company.

Anyway you need to move up the job chain. There is always a ceiling pay for certain jobs. Move up the job market. Don't get stuck with the same job title doing the same thing again and again and expect the salary to increased exponentially. Move up to manage people.

agree..thats why now i am creating more AI to patch all the gaps (and make myself jobless) 

Wait until you ask it to do a real maintainable code. It will fall apart. The amount of code is simply too overwhelming.

Have fun maintaining it down the road.
