Your comment it's utterly wrong.

Go's backstory dates back to Alef/Inferno and Plan9, and tangentally related to Plan9's C compiler suite.

If any, Go was born to replace C/POSIX and all the bloat which grew up over 40, (forty) years. The same with 9front with Unix, which is closer to the Unix philosophy than any close relative, such as OpenBSD. Everything it's a file under 9front, even the windows themselves.

Rust wants to replace C++ mainly.
