I agree, even without resorting to T. machines you would be able to explain it much better easily. The author really just shows how naive he is about this field, and, salt that with a few cocky phrases like "... many with computer science degrees have a weak understanding of the concept—let alone those without any training on it" and you just get a terrible article. As expected from HN, upvotes and front page :D!
