You certainly won't if you don't try! However, here at Jane Street at least, many of the traders are picking up and using OCaml. If traders can do, so can scientists. And if it works for OCaml, it'll probably work for Haskell. (Which, honestly, is quite a bit nicer overall.) Also, the general consensus seems to be that Haskell is easier to learn if you don't already have extensive imperative programming experience. So it's also a good fit for scientists in that sense. If all the needed libraries and tools existed--many do and more will, soon--and it was easy to get up and running, Haskell would be a perfect tool. Happily, it's moving in that direction, becoming simpler and more capable.
