>> Let C++ die! > So when is Apple going to rewrite IO and Driver Kit, and re-base Metal Shading Language in Rust? Death of a language isn't a clear cut thing that really happens, so everyone has their own definition. Some consider a language dead when they fall from former glory, so for a popular language they don't need to disappear, they can even have multiple thriving niches and still be considered "dead" because they are a portion of the usage they used to have (see Python 2, still widely in use, but I can make argument to call it "dead"). Others consider a language dead when direct competitors are used instead of them for new projects (see Perl). Yet others consider a language dead when there's an active and thriving effort to migrate existing applications to other languages. All of these are varying interpretations of "dead language". I would call Delphi, Perl, Python 2 "dead", yet there are plenty of projects in use out there written in those languages, and in some cases even thriving communities. But even if their absolute numbers don't decrease, the rest of the world might continue to out grow them into "irrelevance" (whatever one might want to consider that to be). All that to say: C++ doesn't need to disappear to "die", it doesn't need to die for other langs to thrive, and it doesn't need to "die" even if other languages thrive. It is not a zero-sum game. > If C++ dies Rust will have a hard time replacing its GCV/LLVM backends. > Cranelift as it stands today won't do it. You're comparing a 20 year old project (LLVM) with a 4 year old project (cranelift) that have different goals. It's like comparing Rust and Python, or Fiat and Cannondale: they have some similarities, but any comparison is gonna be stretched beyond use.
