If anything Go is closer to fitting that bill, if only because of its traditional garbage collection. Applications written in Java by definition aren’t too concerned with memory management, and Rust is objectively a step backwards for them.

Rust is a more credible replacement for C++, but there I think it will be fighting inertia. Many C++ devs are actively against changing languages. I’ve also seen people “writing C++ in Rust”, using unsafe everywhere so they don’t have to figure out how to design their code to fit Rust’s model. You then end up with a kind of worst of both worlds.
