I have never seen Golang being used for business logic backends, its Java, Kotlin or .NET, and then nothing else for a long while. It is not expressive enough but shines in other areas, mainly infrastructure.

Remember that "Systems Programming", which is what Golang was designed for, isn't necessarily just Kernel and device drivers, but everything that isn't "Application Programming", and that includes the whole K8S networking and container stuff where it is very successful.
