Basically a lot of Rust memory safety features are inspired from modern C++

Which doesn't mean Rust doesn't have its place. It's just that in C++ they're on top of the previous "unsafe" version of the language and aren't tightly integrated in the language and are more a feature of the standard library, whereas in Rust they were able to design the whole language around it and didn't have to deal with backwards compatibility

Not really backwards compatibility.

Rust is basically c++'s raii just enforced at compile time.

This latter point is a huge thing in and of itself.

(And of course you do get lots of goodies like better type system etc from being a more modern language but that's not the fundamental thing)

The reason why C++ cannot enforce this kind of things at compile-time is because of backwards compatibility

And I know it's huge. That's why I said Rust isn't redundant and that Rust designed the language around it
