So to me this article feels a bit like if someone discovered some really basic fact of computer science, like "you can do algebra on strings. If we define + as concatenation, then we can have an abstract arithmetic that works on numbers, strings or sets...". Which would be swell, but I feel the proper response would be to say that this intuition is backed properly by type theory and point out the best textbooks that would suit the author to learn it.
It is a sad state of "art" "education" that everyone has to go through re-learning everything and there are few references with proper learning paths and a good conceptual approach. While you can learn, it is very inefficient and error-prone.
Of course there's another important thing about mindset: in my computer science example, it is hard to imagine somebody up in arms yelling "stay out of this with your technical garbage called 'type theory', it is going to spoil the author mind!". But it is equally hard to imagine this not happening in art.
