Unlike many other domains, in software development, it is relatively easy to identify whether the software developer properly does his work or not. The relatively high salaries in software development are the result of the difficulties to find and hire software developers. With time, more and more companies reach the conclusion that usually it is more profitable to hire one talented developer than ten (and even more) average ones. The talented developer might be capable of completing a job that even a hundred average ones won’t be able to complete. Companies don’t really care how does the software developer look like, whether he has a mustache or horns… and therefore they also don’t really care about the age. The only thing that counts is how good he is as a software developer. Unfortunately, most developers stop their professional evolution when getting older. They stop taking new courses, their learning capability is damaged and as a result of that they are no longer the great attractive software developers they used to be.
