It's a double-edged sword. Rust gives all the tools to make really performant software and tries to keep inefficient operations visible. But in many situations doing it the "proper" way requires a deep understanding of the type system and a lot of experience so you can tell the compiler what you're trying to do. Most things just aren't performance critical enough to warrant a day of experimentation, and many features don't really need generics and all the syntax overhead that comes with them. When you combine that with perfectionists it can probably get annoying. It's sad this is common enough to drive people away, because I think Rust is a great language and using it "well enough" is the first step to learning how to do it better. Imho it's not realistic to expect everyone to really understand all aspects of traits, lifetimes etc. because those can get really tricky really quick and not every behaviour of the compiler is consistent in those areas.
