Worse, it just makes shit up.
The Purdue comeback in 1981 was total BS. I went and asked ChatGPT a few more times and learned about the 35 point Gopher comeback in 1973 against Michigan. According to ChatGPT, that game is called "The Greatest College Football Comeback of All Time" in CFB lore.
I also learned of a couple of 28 point comeback wins in the 70s and 80s against Ohio State.
Normally this would just be a lark, but real people and businesses are banking real money (hundreds of billion$) and service models on ChatGPT. I'm working on a project with it for a very big, well known, and heavily scrutinized company. It's worrisome that AI is flagrantly making junk up, at the same time people are starting to take it seriously.
I can't ethically put this stuff out there to the public any time soon.
