That friction is trivial. You are comparing the effort of snapping a photo against the effort of actually reading and analyzing a text. If anyone chooses to read the paper, it's because they actually want to read it, not because using AI was too much hassle.

You can certainly make it harder to cheat. AIs will inevitably generate summaries that are very similarly written and formatted -- content, context, and sequence -- making it easy for a prof (and their AI) to detect the presence of AI use, especially if students are also quizzed to validate that they have knowledge of their own summary.

Alternately, the prof can require that students write out notes, in longhand, as they read, and require that a photocopy of those notes be submitted, along with a handwritten outline / rough draft, to validate the essays that follow.

I think it's inevitable that "show your work" soon will become the mantra of not just the math, hard science, and engineering courses.
