I recently finished grad school and accepted a data scientist job a couple weeks ago in part because the job description mentioned expertise with Julia as one of the preferred qualifications (it's rare to see a listing that mentions Julia). It's the language I used for the bulk of my research over the last four years, and has been improving rapidly since it was released. I like Julia a lot more than Python, and I hop…
I don't. It doesn't have the incumbency of R, the use in other areas of programming of Python, or a company actively marketing it like MATLAB. It's not 5x or 10x or whatever good enough than the alternatives to assert itself in the playing field.
If it means you get your work done using it, be all means use it. But I think it will stay around clojure levels of use in data science, statistics, and machine learning.
