It's hard to explain, but the language is one you can throw into a team of random developers and come out with benchmarks, tests, CI/CD pipelines, unified code formatting, and good parallel work models (via goroutines) almost every time. Builds are instant. Built artifacts are a single binary - not 1,200 files that must be moved. Every single package that has any traction is both easy to read and has documentation inline or via published go.dev docs.
It's easy enough the frontend JS guy can write it. It's complex enough you can use goa.design or go-kit to auto generate openapi specs and complex microservice designs that support multiple transports (like gRPC). Errors always get handled because the linter points them out and the devs don't cheat by setting up multi-function try/catch blocks.
I've had less issues with production Go applications than any other language. I don't want it to win over Rust though, Rust is awesome. I want Go to replace Java.
