The answer sounded excellent. The facts had other commitments. For builders who have learned to separate a model's confidence from the evidence supporting its response.

The joke, explained
An AI hallucination is an output that presents invented or unsupported information as though it were reliable. Adding since 2023 turns that failure mode into a mock heritage claim. The date belongs to the joke, making confident inaccuracy sound like an established personal specialty.
For the builder who asks for evidence after the confident answer.

Questions
What does hallucinating mean for an AI model?
It means producing information that is invented or unsupported while presenting it as plausible. The line uses that technical problem as though it were a long-running personal habit.
Does 2023 date the invention of hallucinations?
No. The year is part of the design's mock personal history. It does not claim that AI hallucinations began then or establish a timeline for any system.
