This demo is pretty amazing and will take me a while to digest. A few questions that I'm really interested in hearing the answer to: 1. Will the language work without an internet connection? 2. Will it be free to use? 3. What happens if/when Wolfram the company goes out of business, or Wolfram himself retires? 4. Are all the disparate APIs and sources that the language uses determined by fiat, or can they be customized? What happens if/when the APIs/sources stop working? 5. Given that the language can do things like query your Facebook graph, it seems like there's a lot of API upkeep that the language requires. Is this done by Wolfram? How does this work when I'm running locally (if this is even possible)?
