I use it for parsing through legalese or terms and conditions. IT IS NOT PERFECT. I wouldn't trust it ever over a lawyer. But it's great for things like "Is there anything here that is extra unusual or weirdly anti-consumer or very bad for privacy?". I think it's great for that.
People here are just "it will take jobs it's inherently evil". They said the same about Photoshop, and computers before. I think there are evil uses for it sure, but that doesn't mean that it has no valid usages
