"Like most hubristic UIs, Wolfram Alpha is operating with a completely fictitious user narrative. The raison d'etre of the natural-language interface, stated baldly, is to create a usable tool for stupid people who might be confused or intimidated by a tree of menus. The market of stupid people is indeed enormous. The market of stupid people who like to use data-visualization tools is, well, not. (And since the interface is not in fact easy but actually quite difficult, it achieves the coveted status of a non-solution to a non-problem.)"

Command line, big fan. Big fan.
