I get the impression that the author didn't think through his argument before he wrote it. He starts off saying one thing and proceeds to contradict himself. Really there are advantages and disadvantages to everything. Spending too much time learning new languages and never master CS basics is clearly a waste. However, never learning a new language, or more importantly, never programming in a fashion or environment that is unfamiliar to you, can lead to an insular way of thinking. "If all you have is a hammer, all problems begin to look like nuts," or something like that. Its a matter of being a little bit selective and aggressive with your choices. If a new language is too easy, its probably not teaching you much.
