Good questions. I work with writers only on an ongoing basis (no one-offs) so we get to know each other. The relationships are definitely based on trust. But I get to recognize each writer’s styles, strong points and common typos and areas they can improve on. Would be hard for AI to fake those things. One writer is always wordy. Another is typically jargony. That sort of thing. I don’t use any machines beyond spell check. But I am human, so I allow that I could be duped. I’m confident all my writers are on the up and up though.
