It is unfortunate that you think Rust is not improving the state of the art: no other language is low-level and memory safe, with the same flexibility as Rust.

It is unfortunate that you think Rust is not improving the state of the art: no other language is low-level and memory safe, with the same flexibility as Rust. Rust is certainly pushing the research envelope further than Go, and, anyway, it seems to me that improving on C is something very desirable given the recent spate of horrible bugs in C libraries, caused by memory safety violations (heartbleed etc).
