Go can easily replace Python or Ruby (because it is faster and libraries are available to do what you need). Go can replace Java and C# especially because concurrency is easier and performance is on par, if you can get along with the inferior libraries Go provides. Go cannot replace C++ in any function, because its compiler is just too primitive, low-level things are impossible and libraries will never be on par with what C and C++ have. But generally, Go is nice because there is sufficient tooling to do most things nicely and the language is primitive enough to make the tooling work in almost all situations. Which is different from C++, because tooling there is always too stupid for templates, macros, inheritance and pointers. And it is different from Java where tooling is unusably complex, slow and enterpricey. Also, Go didn't accumulate too many "surprise" misfeatures yet, so code can be more reliably written and reviewed than in any of the other languages the parent named. Panic can be seen as the rare instance of such a misfeature, but usually it is only used to signal typically unrecoverable problems like "out of memory". So it is far from the footgun that exceptions are.
