Wikipedia is the Orwellian Source of All Information, Eventually
Think about it. Eventually we will have a one world government that will control everything, especially knowledge. Wikipedia is probably already the biggest source of information on the internet, and it is controlled content. It will be trusted by all sheeple. The big government will eventually change history and knowledge by simply changing what is in wikipedia. And along the way they will convince libraries to get rid of any paper encyclopedias.
If you have read 1984 then you know what I mean. This will happen faster than you expect. Our tweeting children will turn in their encyclopedia owning parents.
