You've found a 'Traith'. Someone asked ChatGPT a question, ChatGPT did not know the answer and hallucinated one. They post the answer to Reddit / HN / Twitter, google indexes the answer and when someone searches they find the GPT hallucination. In the next GPT training run it's incorporated into the weights. It's an AI generated truth, a Traith. Traith is also defined as "A fishing station or fishing ground, especially for herring" and some herring are red.
