I've been using Julia for a year or two now, and over that time my enthusiasm for the language has waned, not grown. Here's the standard pitch for Julia: C-like performance with R/Python/MATLAB-like expressivity. This is undeniably true. For someone coming from R/Python/MATLAB, you will be able to program as easily in Julia, if not more easily and more cleanly, and get much better speed. However, what I've come to realize now is that you can get something similar from Kotlin, Nim, and Crystal, but those are much more general-purpose, and often are more consistent in their performance. They don't have the same numerical libraries at the moment, but they have a much bigger use-case target, and for something like Kotlin, a lot more leverage from the community. Rust is a lot lower-level, but as the numerical resources grow (and they inevitably will) and layers of abstraction are added, what you will probably get is something very similar to Julia in expressivity but more extensible downward, and probably more performant. Rust has a ton of room to grow, and has many good role models from C (e.g., Eigen). This also isn't even touching on PyPy and things of that sort. I like Julia and still reach for it when I'm starting a project. Often it's worked great, but other times I have to go back to R or Python for some library that calls C, because the Julia library, while usable in a way that pure R or Python isn't, is still not actually as fast as C. Sometimes "on the order of magnitude of C" is not actually good enough, and you need C. Also, if you poke around for benchmarks that aren't posted by the Julia developers themselves, you'll see different conclusions about the real-world performance of Julia, so there's that. I guess I read articles like the linked post, and I end up feeling like they're misleading. Is Julia better for data analysis than R or Python? Yes, almost certainly if you were starting from scratch and not calling any products of outside languages. Is Julia better than R or Python + C as it is in the real world? Not sure, because you still have to call C anyway at some point if you're being honest. Is it better than Kotlin, Nim, or Rust? I'm even less sure. If Julia wants to maintain long-term competitiveness, it has to reach out in the opposite direction of those languages, from numerics -> general purpose computing, because they are inevitably moving from general purpose computing -> numerics, and they are bringing a lot with them.
