Google recently announced their C++ replacement language "Carbon".
Carbon, or Carbon-Lang, is an experimental, general-purpose programming language created to be a "C++ successor". The project is open-source and was started by Google, following in the footsteps of previous Google-made programming languages (Go and Dart).
However for organizations that are already using C++ , it’s very difficult to migrate to Rust. Software written in Rust has properties and modules that non of the languages like C++ or Carbon has. Adapting to Rust for large C++ codebases is almost not practical given that there is no inter-operability."
