title: Will Wolfram Language be always-online to have the latest datasets?
body: <p>In many videos about the <a href="http://www.wolfram.com/language/" rel="nofollow">Wolfram Language</a>, they talk about how it knows a lot about "everything" and shows many examples i.e: <a href="http://www.wolfram.com/language/intro-video.html?KeepThis=true&amp;TB_iframe=true&amp;width=931&amp;height=521" rel="nofollow">in this video</a>.</p>
  
  <p>For the language to do this, will it need to be always able to get  </p>
  
  <ul>
  <li>global populations;</li>
  <li>GDP;</li>
  <li>weather </li>
  </ul>
  
  <p>to name a few?</p>
  
  <p>I understand constants (pi, e, log, days/weeks/months in years etc) can be included but surely will the other datasets need to be downloaded on-demand or can they be cached?</p>
