I wonder how much of the benefits comes from the rewrite itself and not Rust. I have taken really bad hard to maintain very large code bases written in C++ and step-by-step refactored it into bug free maintainable code. In my experience bad code written in any language is hard to maintain. And good code written in any language is easy to maintain. I have worked with C code that was a joy to maintain and C code that was hell on earth. The difference was the skill of the original developers not the C language itself. Rust is a nice step forward but it is not magic. If it becomes popular enough then people will write massive impossible to maintain code in it. It is inevitable. The same goes for microservices BTW. A friend of mine is deep in coding hell trying to maintain a 20 years old 100+ microservices system. There ain’t no silver bullet.
