I would not agree that Go is a good replacement for Java Microservices. I would suggest looking into something like Quarkus (https://quarkus.io https://quarkus.io) and if Java is to verbose for someone, she/he can checkout Kotlin (https://kotlinlang.org https://kotlinlang.org) which is 100% interoperable with Java but clean, modern and pragmatic. With Quarkus you have a very powerful but simple framework that out of the box (GraalVM) can be compiled also to a single binary if you need very fast startup and very low memory consumption. Go evangelises simplicity but when someone has to use it in a bigger project the lang is very cumbersome. You don't have any functional programming features like filter, map, find to manipulate collections. The not null (nil) safety or the magic with interfaces{} does it make non safe especially compared to modern languages like Kotlin,Swift which have the notion of nullability build in the language itself. Dependency Injection support is very limited. I think Go is hyped because of the excellent single binary feature which you have nowadays via GraalVM also for Java, Kotlin as I described above.
