"Best language wins" is not how programming language popularity at the top works. Java, C/C++, JavaScript all have/had various other reasons for their wide use. And of course there's huge inertia, even if a language has the requisite of other forces behind it for "taking over the world" it still takes decades.

But no need to put too much weight on this, lots of languages have more than enough users to be viable for a long time. The top stack overflow languages tend to have poor S/N in the user communities.
