Yeah, Rust is ultimately a different project than Go, and I suspect much of the success of Go is down to stuff like good tooling, default GC, native static binaries, generally easy concurrency, rather than stuff like having as bare-bones a language as otherwise possible. I’d suspect having a focus on fast compilation also helps draw in people from interpreted languages.

It’s easy to write a Kubernetes microservice that performs adequately with Go, and that’s all a lot of people & teams need.
