I have a love/hate relationship with Rust. I love the type system as enthusiast, but as project lead I can't justify relying on so many (partly immature) third party dependencies for business critical stuff.
Go is at my employer's (one of the top 3 car companies world wide) techradar the number one to adopt. New stuff of all kind is done in Go.
So, Go is a huge success outside of Google as well.
Not saying that I'm of any importance for Go, but I'm using Go for personal projects, at work for CLIs and standard backend stuff (APIs + DB, Redis, etc.) with great success.
