"goroutines" is probably the only thing that golang has going for it. But today with async/await in languages like Rust and C#, C++ getting a coroutine implementation, and Java getting fibers, golang is no longer special in anyway in this domain, while it still carries the baggage of a non-expressive verbose language, and performing worse than the aforementioned.

Go is special in that it is significantly simpler than all of these languages, while having a large overlapping domain of operation with each. I'm yet to see a single real-life money-making program written in any of the languages you cited that is as easily readable as a Go program.
