Rust mostly avoided accidental complexity. The complexity it has is mainly from tackling a complex problem of providing memory safety and preventing data races at compile time. In C++ a large chunk of complexity comes from legacy of being a C superset and having to preserve backwards compatibility with all of its old features and syntax quirks, and often surprising edge cases arising from interactions between different features.
