As to the education, I think it's not screwing it up, but reshaking and reshaping it. Copy-pasting meaningless texts was manually automated for centuries. Solving or discussing problems with a fresh mind was always hard both for students and for teachers. (That's how about 70% of my students hated me: they had to learn, they had homeworks, and had to read books.)

In any case, there are always enough Chinese students to come and solve problems. Cheating or not.
