The disconnect you two have is that C++ doesn't force you to always use those safety features. Furthermore due to reasons that are entirely non non-technical in nature will never force you to use them. The reason Rust exists is to solve that problem and the result is that an entire set of bugs, that have plagued developers in the target C++ domain for ages, are literally impossible.

ADT's have been known to be a superior way to express state machines for ages but C++ for both technical and non-technical reasons will never actually get them. Rust solves this problem by starting over.
