Rust's memory management strategy has been described before as "you have to think about it, but you don't have to worry about it", which I think applies to the language more broadly in terms of a comparison vs. C++. The latter is very flexible and powerful, but generally assumes the programmer is perfect, meaning mistakes often won't be caught at compile time and are often subtle to track down, while Rust has the assumption that humans are fallible, so many mistakes are caught. The fact that they're caught means learning Rust front-loads a pile of things, because the compiler complains about them, which can easily make Rust seem more complicated despite the core concepts of ownership/borrowing really being a subset of modern C++.
