Rust only really started to get traction after 1.0 landed in 2015. Even then, writing web services and things like that in rust has only really been ergonomic in the last few years as async/await has stabilized. Rust is still a pretty niche language, and its much easier to admire something from a distance.
Go hit 1.0 in 2012, but people started using it in production before even then.
