Some hold the view that AI helps improve learning efficiency and solve difficult problems. Others argue that over-reliance on AI will make students lose the ability of independent thinking and even cause academic cheating. From my perspective, AI should be permitted but regulated. We should treat it as a useful learning tool instead of a substitute for our own hard work.
