The learning is the point. Learning by nature shouldn't be optimized for efficiency. You learn deeply when you have to read sources, draw conclusions, synthesize information, and connect it to your own experiences. I recall writing essays in grade school and what mattered wasn't the end product but the process to arrive at the end product. The hours of research and analysis... figuring out what was true and what was questionable. When you skip steps 1-10 and arrive at the final deliverable a la ChatGPT, you miss the entire point of the assignment. Unfortunately, students are only judged on the final deliverable.
Truly, I think the only way we get back to real learning is through paper and pencil. The problem is that we've optimized our systems for learning efficiency, not learning efficacy.
