3 out of every 5 I'd say has an element of AI in the writing. 1 out of every 5 is blatantly AI.
They don't need to plagiarize anymore. The AI is just doing everything.

Either way, I shouldn't have to read this dribble. It's already somewhat evident that they're not retaining skills and approaches from the classwork. The assignments submitted equally reflect their inability/unwillingness/laziness by constantly using AI "that will delve into this fascinating and important academic topic." Can we just complete the circle of AI?
