For me personally, the problem with C++ isn't that it has too many features, but that they interact poorly and require complicated rules to makes them work together. To list a few pairs: destructors and exceptions, templates and inheritance, templates and headers, encapsulation and headers, namespaces and operator overloading. At least at the moment, Rust's many features are mostly orthogonal and work well in combination. But in some sense, that makes the learning curve even harder, because you can't focus on an "accepted subset" as you would in an existing C++ codebase.
