I don't believe Go belongs in that category at all, mind you. And I'm not convinced that the fairly major internet presences using it heavily would put it in that bracket either.

I concede (having a fair amount of past experience of functional programming languages, including Orwell, which influenced Haskell) that choosing a functional programming language for development helps you pre-select people who are well-educated in CS concepts. But I am far from convinced that it's an approach that is particularly likely to lead to a crack team of business-focussed developers. It's just as likely to lead to a herd of cats.
