One good thing about Android in this perspective is that many sub-components of it have their own processes (binary), especially around HAL, after Project Treble [1]. This means that you can rely on the process boundary as the language boundary to start small. Also note that Android is more C++ than C. And C++-Rust integration is something Rust has already done in Firefox. The road is paved, at least partially. So I have high hope here in long term.

> And C++-Rust integration is something Rust has already done in Firefox. I don't think this is really true. The simple fact that Rust can't overload functions causes significant grief in a C++/Rust interface, for example. Personally, I now see C++ as an evolutionary dead end--yes, it's going to continue to exist for a bit until we get a language that is ready for game programmers can use. After that, the fall of C++ will be fast. This is especially true since we are now back to lots of projects side-stepping the C++ standard libraries. If you're going to do that, why use C++ in the first place? The simplicity of C is much better suited to being a lingua franca, and much better languages are appearing that can finally be the "Successor to C".
