No, it just means the people that tend to be attracted to these types of languages. Easy to get started languages that hide much of the inner workings from you as a dev.

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.

Haskell hides far more of the inner workings than Python, JS or Go. There's a huge gap between the semantics of a non-strict, pure functional language and the actual execution model.

Sure, except it should be foldl' instead.

StackOverflow is thataway -->

Edit for reason: https://wiki.haskell.org/Foldr_Foldl_Foldl'

There's a big overlap. I moved to Go from Python and tons of Python conferences had Go presentations and familiar names picking up Go.

Same with js, notably that Tj van der something guy.
