Aside from offering nothing new, its design was wilfully, explicitly anti-intellectual. Once you've used an expressive language, having to copy-paste boilerplate becomes very painful. And there's no real USP except Google backing, so it's pretty disappointing to see it beat out better-designed languages.
I didn't mean globally (though on a quick search I'm seeing it place above e.g. Swift, Kotlin, Dart, and Ruby), I meant it's frustrating to see Go be chosen over a better-designed language "in the small", for a specific product or SDK.
