As a middle school student, I believe AI is both helpful and risky. For example, AI tutors like “ChatStudy” explain math problems clearly, saving us time. However, last year, my friend got wrong answers from an AI chatbot during homework. AI lacks human judgment. We should use AI tools wisely — double-checking information and asking teachers when unsure. Technology is powerful, but I think human wisdom is more reliable.
