They're targetting slightly different points on the power/safety spectrum. * Erlang: fault tolerance, distributed systems, absolute performance less important.

They're targetting slightly different points on the power/safety spectrum. * Erlang: fault tolerance, distributed systems, absolute performance less important. * Haskell: correctness important, multicore+shared memory performance a main focus, distributed systems less of a focus (cloud haskell) I wouldn't write my webserver in Erlang, for example, but my distributed object store, that's another story.
