On one hand, digital tools should be viewed as part of modern learning, while on the other, some insist that educational institutions must prohibit any assignments completed outside an exam setting to uphold academic integrity. To what extent should universities allow students to use AI in written work, and how can they ensure such assignments still genuinely reflect students' abilities? Please articulate your position, providing reasons and concrete examples.
