I think you mistake the perceived purpose of college and the actual/intended purpose of college. The perceived purpose of college is this boomer-esque, high school teacher salesman, David Bartholomae-esque approach to 'becoming the very best version of yourself' through the power of learning and transformative experiences, etc. which are high-minded ideals, but ultimately are not the point and purpose of higher education. The actual/intended purpose is sort of like a finishing school, or a sorting process. You will associate with and attend classes with the sort of people you will work with the rest of your life, be neighbors with, marry, etc. Also, I would say college is about deferring adulthood, extending adolescence, preserving the boomer economy, adult child daycare, etc. It's a racket. Also, other than assigning your social value, it's a 'good place' to 'network'.
I would say students using ChatGPT is no worse than my freshman dormitory roommate who got snatched up by the feds for dealing drugs on a grand scale; the guys and gals who risk life-and-limb to party their balls off every night of the week. Most students just do not care. Quite frankly, I am happy that the higher education process has been demystified and injured for everyone as an eidolon, because I think it is a protected, neurotoxic myth. Perish the thought that I am some luddite or anti-education type who wants to make college more vocational. I finished in classics and English at Swarthmore.
What you have said is akin to saying a firearm is for maintaining order, when in actuality, people murder/kill a lot of other people with them year-to-year, which is it's actual intended purpose.
