A nice language for scientific computing after Fortran (some might hate it, but I liked it during my CS studies).
I hope Julia succeeds like Python. I have been using Python for quite a while for scientific computing, machine learning and as general purpose language for web services development. I wanted to use Julia for some machine learning problem for predicting prices (time series forecasts), but familiarity and tool support of Python always kept me back and with Facebook's Prophet (fbprophet) library I could do it easily.
I will definitely give Julia a try in coming months. I like this competition and innovation in scientific computing.
