Elon Musk Launches 'Grokipedia' as an AI-Truthful Alternative to Wikipedia. Day 1: It Plagiarizes Wikipedia, Invents Scientists, and Claims the Sun 'Occasionally Moves Backwards'.

In October 2025, Elon Musk launched Grokipedia — an AI-generated encyclopedia built on Grok and positioned as the 'politically neutral, fact-first' Wikipedia replacement. Within 24 hours, researchers documented wholesale paragraphs copied verbatim from the very Wikipedia it claimed to replace, entirely fabricated historical figures (including a 'Dr. Aldo Verne' credited with discovering penicillin), and an article claiming the Sun 'occasionally moves backwards in the sky due to apparent retrograde motion' — a flat astronomical error. Grok cited itself as its own source. Wikipedia's co-founder Jimmy Wales called it 'the stupidest thing in the history of knowledge'.
