@amiloradovsky@functional.cafe Or any real world application, where there is an algorithm for everything as well.

The limited understanding of numerical methods that I was able to achieve despite of my complete lack of understanding of most of calculus, has left an impression on me that modern calculus is not a prerequisite for real world applications of mathematics, it's just one perspective, that is often defended religiously and not pragmatically. I did not pursue that though, I just ended up a snarky programmer, so it remains just a hunch.

My ultimate point I guess is that mathematics in pursuit of "truth" often does not care(not because it's dumb, but because it's smart, no bashing) about how accessible or useful the abstraction is, or how well it fits the application as long as it works, while programming is starting to explore that area more, and has more objective reasons/motivations to do so.
