Not if the improvement is immediate and profound, and it will be. The AI doesn't even need to be super-advanced, though it will inevitably be. Just being able to personalize instruction for individual students would vastly improve the quality. And once we have 10-year old kids from poorer schools beating private-school non-AI-taught teenagers in math contests, I expect for AI to completely infiltrate education. If it hasn't already.
