雅思写作 Task 2

As online education platforms make courses from the world's top universities freely available to everyone, the role of traditional universities is facing unprecedented challenges. Against this backdrop, is it still necessary to spend years and pay high tuition fees to pursue an on-campus degree? Or is the essence of education being redefined, with self-directed learning and skills certification replacing diplomas as the new standard? Please articulate your stance on this debate, justify your position, and support it with concrete examples.
