Summary
To solve the "2 Sigma Problem" of personalized instruction, the author argues against the current industry reliance on closed-source AI due to significant risks regarding privacy, cost, and vendor lock-in. Instead, they propose using fine-tuned, open-source models that employ Socratic tutoring to foster student autonomy rather than cognitive dependency. This vision is supported by a transparent "Glass-Box Architecture" designed to provide secure, curriculum-aligned, and teacher-supported learning experiences.
