A Toronto-based company, Realbotix, developed an AI-powered humanoid robot named Sally, which was expected to help teach coding, robotics and AI at a high school in Salamanca, New York State, but the plan has been shelved after concerns over privacy and data collection. The debate over Sally raises the question of what makes someone a teacher, noting that a human teacher was once a child, while Sally never was. The article references Isaac Asimov's 1951 story, 'The Fun They Had,' where children in 2157 learn from mechanical teachers, and Park Joong Eun's 2021 film 'After Yang,' which questions whether a machine can become part of emotional lives. Despite the pause, AI is steadily entering classrooms. Many countries and geographically remote areas struggle to recruit enough teachers, especially in S&T, and teachers spend hours on paperwork. If AI can take over routine tasks, explain algebra without sounding impatient, or help a shy student after school hours, it deserves a warm welcome. However, beneficial technologies change things, and a human teacher forgets, while a machine usually doesn't, raising concerns about whether every childhood mistake should become permanent data.
