Yesterday, I wanted to confirm that "Gambling Device" by Frank Herbert, was the short story I remembered about a hotel that forbade gambling. So I asked Claude and ChatGPT for summaries. They so confidently made stuff up, I assumed I misremembered.

Thankfully, archive.org lent me a collection containing the short story, which I quickly reread. It was, of course, the story I recalled, not the stories Claude or ChatGPT had hallucinated.
