Your comment was downvoted presumably because it is flip, but I think there's a kernel of truth here. The blog post correctly highlights that limited math is needed to "do" data science, but this is why we have so many irresponsible data scientists.

I'm currently teaching a data science class intended for mid-career professionals. It requires no college level math. And virtually every topic, I feel like I am doing them an injustice by not being able to delve into the mathematics behind what we're doing. They'll be able to put on their CVs that they "do data science", but I don't trust that my instruction gets them to the level that they really understand much about it.
