Being able to understand the syntax and by implication being able to understand a single piece of code in front of your eyes doesn't mean you will understand what it actually does. If you're talking about a small piece of code mainly using well known APIs, maybe you will understand it perfectly. But with code calling custom functions in a big codebase? Even when looking at a simple function call in a class: - if it calls a function on `self`, where is it actually implemented? - if you pass arguments, can they be mutated? - can the function throw an exception? you can't really answer this questions easily and I would argue answering them in Rust is much easier. Also because tooling for statically typed languages can derive much more than for dynamically typed languages.
