> Rust at this point is 10 years old from stable

Rust is not stable even today! There is no spec, no alternative implementations, no test suite... "Stable" is what "current compiler compiles"! Existing code may stop compiling any day....

Maybe in 10 years it may become stable, like other "booring" languages (Golang and Java).

Rust stability is why Linus opposes its integration into kernel.

In the "other good news department", GCC is adding a Rust frontend to provide the alternative implementation, and I believe Rust guys accepted to write a specification for the language.

I'm waiting for gccrs to start using the language, actually.
