expert in computer programming == expert in computer programming + 4 other things?!? This doesn't make sense.

"You have to walk before you can run."

Or if that's too nebulous, remember that knowledge is a hierarchy and mastery is a perception. In order for someone to perceive you as a master at a particular skill, you must also be highly competent in a number of other tangentially related skills.

But with this article (and I somewhat agree with programming in general), you have to become an expert at running before you can get really good at walking. Then you can start to learn about the finer points of the crawling maneuver, and when to apply it.
