good point, definitely it becomes a commodity when anyone can do that said grunt work. I actually still have money I can earn with my previous employer since they have a feature they want to implement but it requires deep knowledge on everything I built.
For example, I'm one of the only engineers who speaks English and Chinese fluently (both widely used in the company), and as such I'm not very easily replaceable.
how did you get so fluent in other languages? very impressive.
