I don't understand it - it is bad to be too good at something, or better than person X? There is the issue of "loud" people, but what does it have to do with technology? There was a psychological experiment that showed people will assume people who talk/brag more are more competent, even if they aren't. The existence of that psychological effect implies that such braggarts do exist, in all walks of life. But wouldn't it be better to work about your own issues of confidence than complain about unimportant bystanders. I don't think those loud people are very popular anyway. (loud == entitled from the article).
