Well Haskell's prelude is purposefully small and extended by a variety of extensions in the GHC. Prelude + libs + extensions effectively make what we call Haskell today. Just like with Elixir and many other high level languages I don't think it's meant for building low level systems where you're heavily constrained by resources. But why wouldn't it be able to interact with external systems? I'm not having any problems building an API that interacts with a database, caching layer etc.
