Real story
A courtroom. A lawyer standing at the podium looking pale. The judge holds printed pages, circling text in red. On the lawyer's table, a laptop showing ChatGPT. The judge's expression: furious. Harsh courtroom lighting.

A lawyer used ChatGPT to research case law. It cited 6 cases.

The judge checked. None existed. The AI had invented fake case names, fake judges, fake rulings -- with perfect formatting and confident language. Every citation looked real. Every one was fabricated.

The lawyer was sanctioned. His firm was fined. The case made national news. Not because the AI was broken.

Because the AI was doing exactly what it always does: completing the pattern.
