Yes and yes. Julia is better because, having seen the mistakes of 3 x 20 year old languages, it is creating an (incrementally) better PythonRMatlab base language (not libraries). Had Julia dropped into my lap 5-10 years ago I would have been a fool to use anything else. The fact is though, it is very late to a party where everyone has already danced the night away, and just as the music is about to change (massively parallel multi node functional).
