The case that the "idiot author" of that article is trying to make is that unskilled people who encounter technology tend to believe it makes them more skilled than they really are (i.e. more than native skill + skill through technology). This happens because the technology gives them access to activities they once thought (correctly) were out of their reach.
In any case I don't see the "idiot author" anywhere actually blaming the GPS, or making any sort of annoying calls for legislative action to protect us from technology or ourselves, though I only glanced through the article. It seems like more of a "I see this disturbing trend in my society, just thought I'd letcha all know," article.
