Ah, I see what you mean now. The follow up question I have is: so what? Python is an extremely popular language that is built on C/C++. Unless you are a contributor to the rust spec, why would it matter what language the compiler is written in? The way I take it, the rust compiler team can either spend their time trying to get to being self hosted, or they can spend their time making improvements to the language.

Because one of the Rust goals is to improve the security landscape and reduce the use of C and C++. It is a bit hard to achieve such goal if improving Rust requires to some extent, to keep writing C++. Naturally some day the compiler might be fully bootstraped, however that implies throwing away the work being done by legions of C++ devs on LLVM (same applies to be front ends being written to plug Rust into GCC).

  Yeah, it would be nice if the compiler team was dog-fooding, but we need to be pragmatic don't we?

    Indeed, hence why many need to understand that Rust vs C++ isn't a zero sum game, and any improvements to C++'s own security story are more than welcomed.

      Excellent point!
