I do not understand why this matters. Judge the content on its merit. It makes no difference if “AI wrote it”.
It makes a huge difference if the writing was manual or automated. LLMs generate verbose, generic writing, and ideas that could be concisely expressed in a sentence inflate to entire paragraphs. It's disrespectful to readers when the author saves a couple of hours by wasting thousands of their readers.
That's why I only use code written in Vim. Emacs corrupts the othewise identical bits, just like AI. Gets 'em all greasy and then they smell funny.
