What really sets the Wolfram language apart is its gigantic library of functions. Want to look up stock quotes? easy. Weather? easy. Plus tons of other built in functions that would make a machine learning prediction of Coppertone suncreen's stock price based on weather forecast a couple of lines. In another language you'd have to set up the API queries yourself with a library, parse the returns with another library, and do the machine learning with another library. Then you'd have to cross your fingers and hope that an API or library update doesn't break your code. Wolfram promises easy access to clean data and much less heartache maintaining it.
