Don't you think us here at HN include quite a number of people standing centrally when it comes to "anywhere" in the tech industry? This is what I mean, when talking about "us as a community." Of course this does not go for everyone... but for a considerable amount, I'd say. (Myself am certainly not one of them.)

Well, Julia being made for extensive numerical computations and the like, I think it is doing very well, esp. in academical use, which is somewhere it's right at home. If not yet very much in use yet, at least many academics in relevant fields--which frankly are quite a lot days--have heard of the language. If Julia holds enough of its' promises, I don't see why they wouldn't migrate eventually, given time.
I don't see how any lang could get anywhere "fast," no matter how superb it'd be, "anywhere" tends to be sceptical of change if they're fine with what they have.
