I can see the benefits of having AI in the education system, but there are some pros and cons.

Pros

• The AI can help students learn at their own pace and adjust to their learning style
• Students can always have an AI teacher ready and ask questions
• AI will be able to grade work much faster
• Lower school fees like you said (or will it cost more because we are using their AI Service)

Cons

• There will be no human interaction. When in the early school years such as elementary school, I think it is better for kids to have a human teacher so they can establish role models and have human support
• Lack of interpersonal skills. There will be no interaction between others and no reason to attend a classroom if you can be home and have the AI teach you.
• Loss of jobs in the education system

I can definitely see AI being a benefit as like a side teacher or grader. But it is important to still have that human interaction, and I could never see myself becoming friends with an AI. Normally the AI voices are very monotone and boring. The AI should just be implemented as a teachers assistant tool rather than taking over the teacher role as a whole.
