"Wikipedia’s fundamental goal is to spread knowledge as broadly and freely as possible, by whatever means. About 10 years ago, when site administrators focused on how Google was using Wikipedia, they were in a situation that presaged the advent of A.I. chatbots. Google’s search engine was able, at the top of its query results, to present Wikipedians’ work to users all over the world, giving the encyclopedia far greater reach than before — an apparent virtue. In 2017, three academic computer scientists, Connor McMahon, Isaac Johnson and Brent Hecht, conducted an experiment that tested how random users would react if just part of the contributions made to Google’s search results by Wikipedia were removed. The academics perceived an “extensive interdependence”: Wikipedia makes Google a “significantly better” search engine for many queries, and Wikipedia, in turn, gets most of its traffic from Google."
