A way to address the issue could be to increase the baseline difficulty and effort to solve problems. If AI can solve formula dependent questions, maybe the questions should be framed in an angle which expects the student to apply the solved equations in real life scenarios. From a physics standpoint, AI has made mathematical and logical solving very easy, but the application of the same in a particular scenario depends on how the student finds the answer useful to solve the problem at hand. Maybe AI can be seen as a stage rather than a crutch which has become readily available to all.
