What have you contributed? Or are you just waiting for _someone else_ to put in the effort to prove it for you first? Multiply that by every developer in every company, and you start to see why it's not that common.
I am currently trying to write something in F#, which is still OO, only the rest of my team won't let me because there is "no proof it's better". Well, no. And there won't be if everyone says that. And where is the proof C# was better than VB.NET? Oh, right, the proof is VB.NET doesn't look like Java! Curly braces, the only evidence we need!
As long as the majority can hold back the minority that WILL learn something new just to see if it's better, everyone stays with the status quo.
"Just don't make me learn anything new" <- the developer motto.
