Ask HN: What's the longest amount of time you wasted due to ChatGPT being wrong

I was getting some help learning clisp...

...it took me 30 minutes to figure out that it was giving me broken code examples, wrapping variables incorrectly in parens, like:

(format t "You rolled a ~d" (dice-result))

...I still don't really know if I'm learning properly so it's pretty funny in that way. But overall it helped me make a lot of headway so far, even though it made me curious how much time it's caused other people to waste.
