That's the sort of sloppiness you get when you have a conversation with an AI, ask the AI to make a blog post based on the conversation, and then copy-paste that straight into your Substack without reading to see if a fresh reader would understand what you are talking about.
If the author insists on posting more unedited AI text, asking a fresh AI session to critique the post from scratch would probably catch this kind of mistake and lead to a much better result.
