We know that behavioral and cognitive patterns develop at a very young age, soon become ingrained, and usually affect the rest of our lives in one way or another. Kids who are never disciplined grow up to be entitled spoiled brats, so what do you think will happen to kids who habitually delegate any work that requires even modest cognitive effort to a black box?
I don't buy the argument that this is just another technical development that makes things easier and more efficient. The WWW made information easier to find than searching for books in a library and reading them, but fundamentally you still have to read the material, understand it, and apply it to your work. LLMs can just finish students' assignments for them and they don't even have to read it or spend spend any energy thinking about it.
for example: if you had repetitive busywork for homework assignments, it doesnt make sense to spend a lot of time on it, once you have proven to yourself that you know how to do it anyway.
But the second half of your post is kind of mean-spirited. "You and many others are not cut out for a broader education," is a rude, elitist way to call someone stupid. With few exceptions, I think practically anyone is "cut out" for higher education. What that education looks like is obviously different for each person, but that's as it should be, as the world is so vast that the human race can only somewhat learn a significant portion of it all if we all learn something a little (or a lot) different.
The university system is a special time and place that society has carved out where individuals can prioritize learning and experimenting above all other considerations, including (ideally) their job or paying bills. It's amazing that society has prioritized this kind of self-actualization, and "societal-actualization." It's maybe one of our greatest achievements! Anything that cheapens that experience is a shame, whether that is the belief that one's primary value is only equal to what they contribute to the economy, the outrageous costs of college tuition, or the allure to use ChatGPT and similar tools to net easy wins at the expense of building a wonderful mind.
