Anyone who uses ChatGPT or other AI chatbots eventually encounters the confident hallucination. The AI will explain a nonexistent feature, invent a quote, or describe a restaurant that closed during the first Clinton administration.
That's because large language models are designed to produce plausible-sounding responses quickly. That ability is what makes them useful, but it also creates the perfect conditions for hallucinations. The chatbot wants to keep the conversation moving smoothly, so it often fills in gaps with fiction if it's convenient.
