The whole premise of this article was to optimize programs for speed, which is also pointless if your program is already fast enough. They also don't take into account programmer time spent to optimize the project, how easy it is to find programmers that work with that particular language and that can deliver performant software, etc. Your criticism is valid, but I feel like it should be applied to this whole article rather than this particular point. I like how stuff like that is described on the Computer Language Benchmark Game: "… a pretty solid study on the boredom of performance-oriented software engineers grouped by programming language.". You could also probably substitute "boredom" with "ego".
