I guess it all depends on whether or not you think that pure functional programming makes sense as a general approach to programming. Pure functional or not is a very fundamental choice that influences all other features of a programming language. So I don't think it makes a whole lot of sense to compare Haskell to Go feature by feature.

Anyway, I agree that there is no reason why Haskell should be confined to the academic space at all. Actually I think the whole "right tool for the job" mantra is largely misplaced when it comes to Turing complete languages (apart from _very_ low level systems programming).
