Java and C# are memory safe languages, as are common interpreted languages like Python and Ruby. Even JavaScript is memory safe, barring the possibility of subtle JIT bugs that may practically impact such safety.
But op means memory and data safe, without a GC nor a runtime, so it can be used as a systems programming language. For "some reason" people only talk about Rust in this space!
There are currently no widely-used programming languages other than Rust that offer the memory safety guarantees Rust has without a garbage collector. I think this is bad, and I wish more people would develop memory-safe systems languages that explore other parts of the design space like Rust does. But in the meantime, Rust is pretty good, certainly preferable to C or C++.
