When I assign analysis, I am not trying to extract a polished product; I am trying to put the student’s mind through resistance in order to make it stronger. Offloading the struggle to a chatbot does not “free students up for higher-order work.” It deprives them of building the strength to do any substantial cognitive work at all.
If you give up walking, your body gets weak. If you give up reading, so does your brain.
