I believe F# will never be really popular

Think about it: C# already got the cool functional features that have real practical use. When I say this, I think about lambda expressions basically and how powerful they work with LINQ. I firmly believe that better thread handling language features will be incorporated into C# too, and after that F# really won't have any real advantage over it.

Am I right, or am I right?

yes but the tritone has a place as a passing tone when harmonized properly in tonal music. bach used it and its usage was common in the fairly common in baroque and romantic eras.

the tritone chordal substitution is used in jazz (cf. john contrane) the use of which comes from the flat 5 of the blues scale
