An abridged summary is one thing. An abridged summary that editorially chooses which knowledge is worthy of summarizing is another thing. Wikipedia is the latter. The "all knowledge" bit should not be part of the description, because it's not true. Wikipedia actually attempts to create "a summary of selected portions of human knowledge, chosen by those users with the most willingness to endlessly argue on the internet about what should and should not be included".
