I have barely touched Julia and I am impressed by the performance. It could become a real competitor to R.

Nim could also play a significant role because its syntax is similar to Python, and because NumPy is a Python API which is very prominent among scientists. However someone has yet to write a Nim library similar to NumPy.

Nim has the advantage of zero overhead to C, and it compiles to C which makes Nim an interesting option for super computing.

> Nim has the advantage of zero overhead to C,

Untrue. Nim requires the use of a garbage collector.

No. Counter example from http://learnxinyminutes.com/docs/nim/:

  # Because Nim compiles to C, FFI is easy:

  proc strcmp(a, b: cstring): cint {.importc: "strcmp", nodecl.}

  let cmp = strcmp("C?", "Easy!")
