to further retort the article author: You don't have to be that knowledgeable to teach the basics. If the curriculum is binary arithmetic, there's far more skill in trying to articulately convey the concept to someone who has done base10 all their life, than there is actually knowing how to do base2. There's a lot of people out there that are amazing at their jobs/domain - but they absolutely cannot explain it to a newbie. Teaching is a whole skill on it's own.
