I disagree. Hand-authored articles can be slop too. This research is great, and your subjective feelings about word cadence don't affect the information. I guarantee you read AI output every day and don't know it.
The criticism can be restated, then, as “you used AI to write it, and unlike others who use AI to write things, you did a bad job directing it and editing the work.”
Hand-authored engagement or clout (LinkedIn) farming articles and corporate press releases are usually slop, most others aren't. I'd be surprised if corporate press releases today weren't largely AI-written - no one would know the difference.
