I disagree. You learned something at that point it is up to you to repeat it and make it stick and make sure you learned it correctly. No teacher no AI nothing can fix that unless you take the time. Because of this I think it is irrelevant to the topic. I want to go back to the math problem, you can definitely understand the solution and learn it, then it is up to you to practice. Goof thing about AI is it can throw you many more questions to make sure it sticks and help you know what you did wrong. It is susceptible to mistakes, yes but first of all those models are not made to be math teachers and real teachers also make mistakes. One advantage of AI is it can tirelesely explain the solution to you again and again unlike a real person.
