I agree partially with this article. I think programming in a highly expressive language and runtime is a great way to get started exploring and develop intuition. I solved differential equations using mathematica in middle school, long before I even learned how to integrate. I solved instances of the traveling salesman problem long before I understood how complex it is. I played around with images and video files long before I learned anything about signal processing. I find that it is very helpful as a student to be able to learn from bottom up and top down simultaneously. Mathematica is much more forgiving than python if a student has no prior programming experience.
