It's fantastic that so much written knowledge is becoming generally accessible and cross-linked these days, but this is just an intermediate stage-- a universal library on the way to becoming a universal brain. The missing piece is encoding the underlying meaning of the stored text, the deep-structure logic behind it. It's one of the oldest challenges in Computer Science, and there has been lots of progress and companies dedicated to doing this. Powerset, for example, has software that has parsed and can answer questions from all of Wikipedia.
The thing is, you really still need a person to get it most reliably right, because people understand the way the world works. Luckily, we already have people whose job is very close to doing this already-- they're called fact-checkers or researchers, and they work for every reputable publication.
