One of the very few times that you try to stay on topic, and your oversimplification on complex issues shows how much “truth” you carry.
How many kids do you know that they study willingly by themselves, without any guidance by parents or teachers? The vast majority of children want to play, not to study. Only a small portion of kids have self-discipline.
That is why AI is overused today, because pupils and students are lazy, they do not want to put the effort of learning, they just want the grade to pass the courses. AI is a good tool, but if students use it recklessly, it becomes another cheating mechanism.
Schools are in place to ensure that the majority of the kids should learn some basic knowledge before becoming adults. Maths, physics, chemistry, history, geography etc are seen as useless by people that do not use them directly as adults, but the courses are not only to give you specific knowledge. They aim also to teach you how to obtain knowledge at different disciplines. For instance, a cook mixes materials, so concepts borrowed from chemistry can be useful.
