i think wolfram language is so deep. and i am so weak to grasp or follow it and its the same problem with Stephen wolfram that he could explain to people in a single lecture i watched it a lot in ted x, Harvard and other university he talked but for me its not easy to grasp,(reply>), don't worry, he always repeats the same demo over and over because it is shockingly impressive. Real wolfram language takes a bit to learn but it is not harder than the domain languages it implements, so if you know about economy and programming then you could find wolfram language easy for economic related things, but not for chemistry.
