One use for Chat GPT I've found that's super handy - and something search engines have been really bad at - is finding me a word that I can't think of. Give it a description of the word's meaning, and maybe the context for how it would be used and it's given me pretty great results. It was such a relief figuring this out cause I'm terrible at recalling words sometimes, so I've wanted something like this for YEARS.

On the same context, it's quite good for neologisms which could be great if you're looking for a new company name, or a product name, or whatever. You give it two words and ask it to make combinations and then it goes ballistic producing them by the buckets.

Early search engines would publically show what people were searching for.

It was amazing how prevalent silly/embarrassing questions were. Things like "can kissing cause baby?"

There are some fun YouTube videos (old ones) making fun of funny Yahoo! Answers questions that appear to be written by 10-12-year-olds.
