@neauoire C happened because Unix was built in it. It was not load bearing before, and attempts to replace it have yet to displace it becuase nobody's dogfooded a whole OS (kernel and all) in any other language yet.
I refuse to care about Rust/Go/Swift until a usable OS exists written in one that can rebuild itself under itself without needing any other language to complete that basic circle. It's not a load-bearing systems language otherwise, just a parasitic growth on the C ecology.
