What the author describes is just one step into becoming a godlike developer. I can't find a link / attribution right now, but it starts off as new, then you get skills and start to feel smug and good about yourself - which is in a lot of cases combined with a hating on other developers or packages. The next two steps are disillusionment - taking a fall, realizing you're still a very new developer, etc, and only from there on out do you start to develop into a more exemplary Good Developer.

Or not, everyone's different.
