What happens to schools if AI becomes a better teacher?

Luis von Ahn, CEO of Duolingo, recently shared his vision for the future of education on the No Priors podcast with venture capitalist Sarah Guo, and it centered on AI transforming the very role schools will play.

"Education is going to change," von Ahn said. "It's just a lot more scalable to teach with AI than with teachers."

That doesn't mean teachers will vanish, he emphasized. Instead, he believes schools will remain, but their function could shift dramatically. In von Ahn's view, schools may increasingly serve as childcare centers and supervised environments, while AI handles most of the actual instruction.

"That doesn't mean the teachers are going to go away. You still need people to take care of the students," the CEO said on the podcast. "I also don't think schools are going to go away because you still need childcare."

In a classroom of 30 students, a single teacher can struggle to offer personalized, adaptive learning to each person. AI, on the other hand, will be able to track individual performance in real time and adjust lesson difficulty based on how well each student is grasping the material, according to von Ahn.

Imagine a classroom where each student is "Duolingo-ing" their way through personalized content, while a teacher acts as a facilitator or mentor. "You still need people to take care of the students," he noted, "but the computer can know very precisely what you're good at and bad at — something a teacher just can't track for 30 students at once."

Education is slow to change, so this may take many years, von Ahn explained, noting that regulation, legacy systems, and cultural expectations all serve as drag forces. Still, he sees a future where AI augments or even supplants parts of formal education, especially in countries that need scalable education solutions fast.

It's a provocative vision, one that raises deep questions about the future of learning and what we expect from education in an AI-driven world.
