This was a great read. We need more books like rust for c++, or rust for Java coders. You already have a good grasp of programming, but learning things like this is never well explained in books that try to learn you programming from scratch in their new language. Those books are too introductionary and therefore quite tedious.

One problem in trying to teach a "conversion" type approach is that if you didn't really understand a thing in language A where it was maybe not too important, what do we tell you in language B where it's identical (or even mostly identical) but now crucial ?
If we teach you the important thing, language A people who did know wonder why we're wasting their time on a concept they knew, but if we do not teach it, anybody who got by in language A without this understanding is now screwed in B where it's very important.
