OP here, I used in the past Go (2015~2016) and Rust (2017~2018) at few years ago, my experience in favor of Go was:

+ Faster compilation time (really more faster!)

+ Concurrency model embedded in the language as built-in features

+ Language stability

My main job in Go was done in the Google project u-root: https://review.gerrithub.io/q/owner:manoel_vilela%2540engine...

My experience with Rust was just toy projects like this:
