X owner Elon Musk said Tuesday that his artificial intelligence company xAI is working on a Wikipedia alternative that will be “a massive improvement” over the information site.

Wikipedia co-founder Larry Sanger discussed on the Tucker Carlson Show how the website has gradually shifted since its introduction in 2001. Sanger said on Monday that anyone can find a “color-coded” list on Wikipedia’s site showing “reliable” and “perennial” sources, saying Fox News, Daily Caller, and the New York Post are among the “blacklisted” sources.
