When I was in third grade, I had to show the intermediate steps I used to formulate an answer to prove that I knew how to do the task. This has two benefits: (1) it gets students in the habit of working through a problem methodically, and (2) it lets teachers assign partial credit when students get the methodology correct but make a simple error.

Similarly, this is why we students have been required to cite sources instead of simply rendering an opinion on a topic. Most of these AI bots are just fancy plagiarism machines.
