A kind of quantum encyclopedia, where genuine data both exists and doesn't exist depending on the precise moment a person relies upon the encyclopedia's discordant fucking mob for information.

Wikipedia has some serious problems. Wikipedia articles/entries that are about History or Politics are often unreliable, extremely biased, and incredibly one sided. There are many examples of Wikipedia articles totally contradicting each other and presenting the contradictions as fact. There also many examples of Wikipedia articles stating totally FALSE information with weak citations and evidence that readers think is factual.

Wikipedia can be edited by anyone, content can be changed by anyone for any reason, so each article will most likely be written by someone who has a passion for the topic and therefore a bias for or against it. Wikipedia administrators are shadowy figures that can have very strong biases, and they control what you see and read on Wikipedia, effectively altering public opinion to fit their narrative and beliefs. Take what you read on Wikipedia with a huge grain of salt.
You read that on Wikipedia? Ha! No wonder it's not true.
