If Scheme is so good why MIT drops it?

No, OCaml is in the same boat as Python. Spawning a parallel work item takes
20,000x longer in OCaml than in F#. Gathering the results is asymptotically
slower in general. Consequently, for most problems, Python or OCaml running
on an infinite number of cores cannot beat F# running on 2 or more (and I
already have 8) because the overheads are far too high for parallelism to
pay off.
