Probably some, but in the industry I'm referring to, nobody is going to let you write a critical system in some new relatively unknown language. Options are Fortran, C, C++, or Java. Julia is cool, but still really new in the cosmic scale.
Whose permission do you seek who will "let you" or not "let you" write a critical system in some new relatively unknown language? What if you work for yourself or are creating a startup?
