I use it all the time. It is a good partner to challenge me, when I am looking for other points of view. "I believe x due to y. Challenge my point of view"

It helps me explore a topic fast, so that I know the lingo to search for it myself. I use it for making low stakes decisions where it often succeeds, such as shopping and research for shopping. I validate the results every time.

Is it net negative for society, not sure, maybe? Will it go away, no. So we should embrace it, but not the big tech AI, but smaller LLMs.
