I've criticized it whenever it gets brought up as an alternative for academic research, coding, math, other more sophisticated knowledge based stuff. In my experience at least, it falls apart at reliably dealing with these and I haven't gone back.
But man, is it ever revolutionary at actually dealing with language and text.
As an example, I have a bunch of boring drama going on right now with my family, endless fucking emails while I'm trying to work.
I just paste them into chat gpt and get it to summarize them, and then I get it to write a response. The onerous safeguards make it so I don't have to worry about it being a dick.
Family has texted me about how kind and diplomatic I'm being and I honestly don't even really know what they're squabbling about, it's so nice!
