Maybe it will be unpopular opinion but if your idea has to be explained after 50 years in a blog post maybe it was not that good after all. Or maybe idea was good but state of the tools and culture of your field is not best place to implement it, like the blog post ask: what tool you would use for literate programming? Or you need to write a tool for literate programming first? For me it sounds bit like runnable python notebook, which is great for DevOps stuff but not really for developing financial system. And I do not want to start about lack of tests as author states.
