I don't know. Isn't this a subsystem that hides the flaws.

Writing the article exposes some flaws but even then, most professors who read this aren't going to be able to pick out of a line up which of their students have used such services.

Widespread cheating means people don't take education seriously for whatever reason. Cheating frequency is an indicator that the education system is doing something wrong. "The customer is always right" is applicable here.

A similar attitude existed in the USSR. Students cheated cooperatively to stick it to the man. When education is "the man" it's a sign that something must change. People see it as another obstacle, not a stepping stone. Cheating became socially acceptable.

You could detect it with software, make students use an app that records the time of every keystroke and save. If a paper is written too quickly, while shorter papers from the student were not, it's a red flag.

But that would make the problem worse, cheaters will get smarter, detecting them will get harder. Educators must try new things so that people won't want to cheat in the first place. Then after detecting cheating they should use it as a metric of their own performance. Otherwise we're well on our way to social acceptance of cheating.
