In this EdTechnical Short, Libby and Owen explore how AI might reshape teaching through the lens of the “weakest link” theory from economics. They discuss the possibility of full job replacement, partial task automation, and productivity gains for teachers. Automation often shifts the composition of work rather than eliminating roles, as with bank tellers and radiologists.

In schools, planning, grading, diagnosing student understanding, classroom management, and relationship-building are tightly interconnected. Automating one component may reallocate time, but complexity is not neatly reduced.

AI can already perform isolated teaching tasks. What happens to the education system when those tasks are embedded in a deeply relational profession?
