The difference here is that your final sentence in your previous comment is what AI is specifically used for, not just in school but everywhere. Though I do agree that removing grades won't fix it:

the only issue is the students turned off their brain and got lazy, removing grades sadly won’t stop this behavior

The way AI is used is exactly for that reason. To turn off your brain and get the right answer without understanding the how or why - or even if there is a right answer or not. Writing and the entire breath of the arts are different from STEM in that oftentimes there is only your voice and what you want to say, and using AI largely removes your voice from the process.

It's not an issue inherent to AI in this regard, but AI definitely exacerbates it by making it much easier. Let the robot tell you what to think and what the correct answer is.

When I was still doing math in school, they wanted us to write out the equations that we used to get our answer and most teachers would give you partial credit even if you got the wrong answer as long as they could understand the logic of how you got there, because the point wasn't to get the answer right so much as to prove that you understood the concepts. And even then, it was constantly drilled into us that getting a good grade was the only thing that mattered. The rote memorization and regurgitating the desired answer for every test in every subject practically killed my love of learning. It took me years after getting out of school to realize again that I actually did enjoy learning new things. AI simply allows kids to regurgitate the correct answer faster and more efficiently, with less effort on their part. It's Cliff Notes without even having to look at the Notes part - just ask Cliff to write your answer for you. The way school is set up unfortunately outright encourages this thought process.

The modern school system was created partially during the industrial revolution in order to churn out factory workers who could repeat a rote task day in and day out. It wasn't created to make free thinkers and inspire creativity, and how we use AI reflects that. There's no desire there to put in the effort to say what you want to say or an enjoyment of the process (which is a major thing that a lot of artists enjoy about creating - the process can be even more important than the final product), only the desire to obtain a "good" product, whether that's a good grade or something else like Gen AI images to post for Twitter likes.
