This is really fantastic of course, but the video doesn't answer the following question: The video says it’s the most powerful language, one can build so much etc. What’s one of those things, that they've built that no one else could build before? What great application now exists that didn’t before? I will still use google for search, twitter for opinion (that’s where the people are at..), photoshop for photo manipulation etc. Besides doing mathematics, which Mathematica is great at, what concrete evidence is there that this language is better for solving any particular problem one would actually care to solve? I don’t care about dominant flag colors.
