It's well known that generative AI cannot fucking spell. It doesn't know how to because it wasn't programmed with actual logic. It's trained to find patterns and fill results with things that match the pattern. So it somehow deduced "um" and "fruit" both needed to be in the results and searched for that, but then it doesn't know what actual fruits are and it doesn't actually know how to spell so when a result turned up "coconut" it couldn't tell it didn't end in "um".
Edit: I went and tested it with copilot. oddly enough it could do the spelling with fruits but NOT with prime numbers. It wasn't just a list of all primes, it just couldn't spell numbers.
The vast majority of memes like this get patched as soon as they become viral. Some developer somewhere very likely manually entered a list of fruits ending in "um" and got the LLM to refer to it when asked.
Hmm. I wonder where Lemmy is on the social media virality train. I think the flow used to be (roughly, many years ago): twitter, reddit, instagram, facebook...............myspace.
You know, not many years ago this would have been amazing. Still not appropriate to adulterate search results with... but amazing nonetheless. Is google, like, a decade behind the curve?
