So are you saying that in the future, you could have a system where you type a statement as a description, then conceivably, be able to hover over items in the description for data. E.G.: the statement "San Francisco's population is largely made up of imigrants to the bay area, where an estimated 20% of the inhabitants are actually native San Franciscan born"

Where hovering over "San Francisco's population" would give you the data-point from wikidata?

Is this not the level of parsing that Wolfram Alpha is trying to do?

Also, it would be really interesting to see the following:

Assume you create new google doc, and as you begin typing, in a small window/pane/pop-up, relevant information is displayed based on the context of what you are typing with subtle highlighting. As you typed out "San Francisco's population" that phrase would highlight and the context indicator would display that number.

What would be interesting about this is that if children where using a system like this from their early school days - would they passively absorb such information? would it be annoying or useful?
