College writing will go the way of calligraphy. Colleges and the faculty that staff them need to keep up with the times or risk being obsoleted. Instead of teaching students to write, they should instead offer courses on prompt engineering and how to get the LLMs to spit out what is needed, in a minimum amount of time.
And let's face it -- most people are being prepared for the life of a corporate worker or laborer. I'd argue a great number of people don't need college. Cheating is widespread because there are people in those courses who aren't interested in the material. A quick course in how to compose an email, workplace communication should be all that is needed for most white collar workers. Those who really want to study writing should be offered the courses as an artistic, historical and anachronistic pursuit and those courses should definitely not be financed on the tax payer's dime.
