Acharya Prashant addresses the limitations of AI-based spiritual tools like GitaGPT, explaining that a real teacher possesses the unique ability to choose silence or refuse to answer, which a program cannot do. He emphasizes that while AI provides identical answers to everyone, a wise teacher answers the questioner rather than the question. The teacher's role is not to validate the ego by providing answers, but to dissolve the questions entirely, helping the individual realize that their inquiries are often irrelevant shadows of the ego. The goal is to go beyond the need for questions rather than merely accumulating information.
