ai is good in teaching

You're assuming AI teaching is categorically "good" without defining what good means. Good for whom? Good at what cost? AI excels at scalability and personalization, sure. But it strips away the irreplaceable human element: a teacher who reads the room, adapts on instinct, challenges a student's complacency, or inspires through genuine passion. AI delivers content. Teachers transform thinking. Here's your real problem: you're measuring "good teaching" by efficiency and access, not by depth of understanding or intellectual formation. A student who never struggles, never gets pushed by a human intellect, never experiences real mentorship doesn't learn better. They learn faster. That's not the same thing. What specific claim about AI teaching are you actually defending?
