C'mon! Let me assume that you do not know what the AI we are actually talking about are used for. Depending on the AIs in question, they are not manipulators or encouragers of lazy writing, but instead, they are teachers, tutors, correctors and mentors. They show you your wrong English, punctuation and others, and will also suggest the proper way they should be done for you. However, you construct your words and their meaning yourself, and not them.
This can't ever be a setback for the forum but can instead improve the league of good writers and reduce the garbage we read daily on the forum. If you must know, and maybe you will do research on this as well, to know that you got it all wrong because Schools, Businesses, Media houses, Freelancers, Editing firms, Scriptwriters, Publishers, the Government and many more are using it. It is good to the extent that I've read from sources that Western schools encourage it for their students to improve their English speaking and writing.
Using them correctly, especially Grammarly, I can assure you that you will pass your professional English exams with good grades. Not to mention that its tutoring is faster than theoretical learning. Is that what you call a setback?
