They downvote you but you're lowkey might be right. I relate to what you've said, I also have a huge experience with ai chats. No way one moment it's all mistakes/missing words and written in a casual-ish style and the other the description gets literature style with all the proper grammar present. I'm not even mentioning how there's obvious popular quotes that ai like deepseek and ChatGpt often repeat over and over in their sentences.
Thank you, your points are quite valid. I was hoping that someone would also notice this and confirm my thoughts. You've done this even with examples ! But unfortunately, for some reason, some people tacitly disagreed with this, though I also noted that the author did their best in many other ways. Apparently some people can't read more than two sentences before making a decision.
