I use AI myself for papers, assignments and thesis work, and not only to improve text I already wrote. I also use it to help generate full sections, such methodology, discussion, conclusions, and so on. Of course I still edit, check and adjust the output, but AI is doing more than just fixing grammar or making sentences sound better.
From what I see around me, a lot of students seem to use it in the same way. Not just “I wrote everything myself and AI only improved the wording”, but actually using AI to create large parts of the text and then adapting it a bit afterwards.
So my question is: is this basically the reality now? And honestly, can professors even control this properly? Because unless someone submits a very obvious AI text, how can they prove it was not written by the student? A student can always say: “I wrote it myself.”
