The commercial product is the paper that says "University of Whatever says you learned Whatever". If the university loses credibility (by producing a bunch of people who cannot function without a chatbot) then the product is no longer valuable.
Luckily for us all these good natured AI people will liberate us from the necessity of our own value and places like universities, which give us structured environments to participate in intellectual pursuits, will be in high demand.
This assumes every degree is valuable in the marketplace, which is simply not the case. The product is luxury attendance, the degree is secondary to that.
