I've been playing around with Open AI's ChatGPT, a generative algorithm that answers questions. I asked "What is the Decktet?" and it replied—
The Decktet is a deck of cards created by P.D. Magnus in 2009. It is a unique deck that consists of 36 cards, each of which has a different symbol or suit. The Decktet is designed to be used for a wide range of card games, and it has gained a dedicated following among card game enthusiasts. The Decktet is notable for its unusual design and its versatility, as it can be used to play many different types of card games, including traditional games like poker and bridge, as well as more obscure games that have been created specifically for the Decktet.
My first reaction was that this was uncannily good. My second reaction, though, was how many details it got wrong. As the BGG entry will tell you, the official release of the Decktet was 2008. It was actually created a few years before that. And you can't use it to play poker or bridge, at least not in the usual sense.
