I also have the impression that the research that went in this article is a quite light. R, ML, Python serve different purposes. Julia is cool but brand new and feel kind of out of place compared to the heavy weight that are the other three. The point the author makes about ML and R being black boxes is misleading. At least, R is open source and you can always look at the gut of the software, nothing is more easy.
