As someone who isn't super proficient in Java I usually find Java daunting to get started with full of buckets of "meta" issues like in my other comment. What JVM do I use? Does it matter? Does it matter what version I install, what if I have to install/manage multiple versions? If I want to write a web service can I use vanilla Java stdlib or do I have to use Spring or some framework? If I use Spring, do I have to get into the weeds of dependency injection and other complexity to actually get my app off the ground? With Go, none of those questions exist. I install the latest Go, create a main.go file, I use net/http and I'm off to the races.

I think it's good that Go, among other well-made toolchains, brought attention to importance of good CLI UX. But it's not something that is unique to Go: dotnet new web dotnet run curl localhost:5050 also 'dotnet watch' for hot-reload.

Besides what neonsunset points out for .NET world, where alongside C#, we get the pleasure to enjoy F#, VB and C++/CLI, it is relatively easy for Java. When one doesn't know, just like with Go, one picks up the reference implementation => OpenJDK. For basic stuff, the standard library also has you covered in the jdk.httpserver module. By the way, where is the Swing equivalent on Go's standard library?
