ChatGPT already made it so that you could easily copy & paste any full-text questions and receive an answer with 90% accuracy. The only flaw was that problems that also used diagrams or figures would be out of the domain of ChatGPT.
With image support, students could just take screenshots or document scans and have ChatGPT give them a valid answer. From what I’ve seen, more students than not will gladly abuse this functionality. The counter would be to either leave the grading system behind, or to force in-person schooling with no homework, only supervised schoolwork.
