I don't think that's correct. I think the main strength of F# lies in its interoperability with C#. Basically C# and F# are 2 different languages that are good at solving different problems, and are mastered by different people. C# is a solid infrastructure language. F# is a good business modeling language. What I think is best about F#/C# is to have data scientists / mathematicians work in a language and have infrastructure people work in another one, and yet have those 2 languages interoperate well. The main issue for me is that they don't actually interoperate very well... If F# is pushed too far from C#, what's the point? Just use Haskell...
