This happens often in music, where subjectivity comes into play. What's not immediately obvious: programmers use subjective measures of quality all the time. We have to do so to get our work done in a timely fashion.

Those who want to be truly great should be humble. They should also check themselves as much as possible with objective measures and feedback from trusted and respected fellow practitioners.

Come to think of it, I suspect this phenomenon affects the implementation of programming languages. A lot of second tier CS talents implement languages because they have enough ego to get through the ordeal.
