Curious what the committee members think of the new competitors to C, e.g. Go, Rust, and Zig. Any comments?

go isnt a competitor to c

F-Secure apparently thinks otherwise,

As does Google,

Naturally if one is talking about specific uses cases like IoT with a couple of KBs, MISRA-C, or UNIX kernels, then yes Go is not a competitor.
