I've always been fascinated that some people don't seem to have any email "voice" - they just can't translate email text into human emotional impact. So they write super abrupt emails, things they would never say in real life, totally different to their actual personality. It's almost like a distinct form of autism. Meanwhile I'm almost the opposite extreme - I can't hit send on something unless I've finessed it until it sounds exactly like how I would communicate in person. It takes me ages to write my emails.
I'm starting to get a feeling there is a phenomenon like this with AI - some people just genuinely don't hear the AI "voice" at all. They really can't distinguish why sending AI written text is going to impact the person at the other end. It's going to be an interesting ride as these people start using AI and are completely baffled why people are offended by their perfectly reasonable responses.
