Is said teacher "giving up their own thinking" or just lazy/desperate?
Based on a reddit comment from the post: "It was allegedly 3 different essays about agricultural science occurring in the last few months of classes. The professor elected not to grade them until today, (graduation was yesterday) so now the university is withholding an entire class’s diplomas after they walked the stage."
So this teacher is both a) blind as to the capabilities of ChatGPT and b) didn't do his work until it was almost too late.
If he had used some non-BS method of "detecting" plagiarism and applied it evenly through out the course, that's something else. Nope.
The said "teacher" should know that ChatGPT will give lots of false positives.
