College students don't take classes to learn; they take classes as part of a transaction to earn grades, a form of capital that is eventually exchanged for a degree. In many cases actual passion about learning might hurt your grade if you spend effort outside the transactional scaffold and study extra topics or make personal projects. The assignments themselves are reduced to formulaic checklists that can be graded by an unskilled intern or TA, where essays with a topic sentence, three body paragraphs, and minimal grammatic errors are given full marks even if they're just academic drivel (or more or less bullshit).
So of course students end up cheating or checking out and not learning much, just fulfilling requirements until they finish. A student using GPT to do assignments is naturally robbing themselves of any learning opportunities offered by the assignment, but it doesn't matter in this context of grade transaction being valued over actual education.
Maybe if we moved away from traditional grading structures we could better our system around real learning and development.
For a while I had hoped that bootcamp style education might be able to get around some of those issues, but those have largely been warped around job placement statistics and so now teach the bare minimum to fool a recruiter into giving you an interview and maybe an offer.
