Is Julia actually used that much? I've been hearing people herald it as the next big thing for the last five years or so, but it doesn't seem like it has taken off. I personally don't know anybody who uses it professionally (I know plenty of people who use R professionally). The most recent SO survey also indicates that it is rather unpopular.

Julia just got to 1.0 last year, and it does have areas where it's already between the best options in scientific computing such as differential equations solving and mathematical optimization. Regardless of not being the most popular (against the behemoths that have many times it's age and support), you shouldn't have trouble doing most stuff with it from machine learning to statistics. And it's a pretty fun and fairly unique language to learn and use.
