Imagine a search engine that, instead of just doing text matching, attempts to parse your statement into questions it can answer, then provides you with as many of those answers as it can. Imagine a search engine that can deal with numerical relationships and analysis. Imagine a search engine that’s tailored towards returning facts and knowledge instead of websites.
Now, go watch the Wolfram Alpha demo video.
Next, imagine if you had analytical tools of this nature at your fingertips at all times, and were able to project and share them on surfaces using some form of augmented reality. Finally, imagine what this could do to intelligent argument, discussion, design, and political discourse.
Quite a step, huh?
