Articles like this help scale mathematical knowledge to run on a greater number of minds, so helpful, and thank you to the OP! While practical skills and competence are the necessary conditions for understanding maths that can only come from practicing and doing, we also need a bigger funnel of people with intuition and curiosity so as to move more people through the pipeline of curiosity, to competence, to mastery, to innovation. I hope as a culture we start to encourage more treatments of difficult topics like this article.
