Why AI Might Be Your Next Teacher (But School Isn’t Going Anywhere)
Luis von Ahn, the co-founder and CEO of language-learning app Duolingo, recently made a provocative claim: Artificial intelligence (AI) can teach certain subjects more effectively than human educators. But before you imagine a dystopian future where robots replace teachers entirely, he adds a caveat: Schools aren’t disappearing anytime soon. Why? “Because you still need childcare,” he quipped.
This statement, delivered during a tech conference panel, has sparked lively debates about the role of AI in education. Let’s unpack von Ahn’s argument and explore what it means for students, teachers, and the future of learning.

The Case for AI as a Supercharged Tutor
Duolingo, used by over 500 million people globally, relies heavily on AI to personalize lessons, adapt to individual learning speeds, and provide instant feedback. Von Ahn argues that AI’s greatest strength lies in its ability to “scale what great teachers do” while eliminating human limitations.
1. Infinite Patience, Zero Judgement
Human teachers, no matter how skilled, have bad days, biases, and time constraints. AI, on the other hand, offers consistent, judgment-free support. A student struggling with verb conjugations at 2 a.m. can open Duolingo and receive the same quality of instruction as during peak hours. This 24/7 accessibility is particularly valuable for learners in regions with teacher shortages or limited educational resources.
2. Hyper-Personalization
AI algorithms analyze millions of data points to tailor content. If you consistently mix up “ser” and “estar” in Spanish, the system detects the pattern and drills those concepts until mastery. Traditional classrooms, even with differentiated instruction, can’t match this level of granular adaptation.
3. Instant Feedback Loops
Waiting days for a graded quiz or essay feedback slows learning momentum. AI provides real-time corrections, explanations, and encouragement. For skills like language or math, where repetition and immediacy matter, this accelerates progress.

Why Human Teachers Still Matter
Despite AI’s advantages, von Ahn isn’t advocating for teacherless classrooms. He emphasizes that schools fulfill roles beyond pure academics—social development, emotional support, and yes, childcare.
1. The “Unquantifiable” Skills
Critical thinking, creativity, and collaboration are best nurtured through human interaction. A chatbot can’t mediate a heated debate about climate change ethics or inspire a love of poetry through shared enthusiasm. Teachers model empathy, curiosity, and resilience in ways algorithms can’t replicate.
2. Motivation and Mentorship
Great educators don’t just impart knowledge—they ignite passions. A middle school science teacher’s excitement about a Mars rover mission might spark a lifelong career in aerospace. AI can recommend content based on interests but lacks the emotional intelligence to recognize a student’s unspoken potential.
3. The Childcare Factor
Von Ahn’s blunt childcare remark underscores a societal reality: Schools are integral to workforce functionality. Parents rely on schools to supervise children while they work. Even if AI could theoretically teach kids at home, the logistics of full-time remote learning (as pandemic-era homeschooling revealed) are fraught with challenges.

The Hybrid Future of Education
The most plausible path forward isn’t AI versus teachers but AI alongside teachers. Imagine classrooms where:
– AI handles repetitive tasks: Grading quizzes, identifying knowledge gaps, or drilling multiplication tables.
– Teachers focus on mentorship: Leading discussions, designing projects, and addressing socio-emotional needs.
– Parents gain transparency: Real-time AI dashboards showing a child’s progress, reducing guesswork during parent-teacher conferences.
Startups like Khan Academy and Quizlet already blend AI tools with teacher-led instruction. For instance, Khanmigo, an AI tutor developed by Khan Academy, assists students with math problems while alerting teachers to common stumbling points.

Potential Pitfalls—And How to Avoid Them
AI in education isn’t without risks:
– Over-reliance on tech: Students might prioritize app-based learning over critical human interactions.
– Data privacy concerns: Safeguarding sensitive information about minors is non-negotiable.
– Equity gaps: Schools in underfunded districts may lack resources to adopt advanced AI tools, worsening educational disparities.
To mitigate these issues, von Ahn stresses the need for ethical frameworks and public-private partnerships. Governments and tech companies must collaborate to ensure AI serves as an equalizer, not a divider.

Conclusion: Schools as Community Hubs
Luis von Ahn’s vision isn’t about replacing teachers but redefining their roles. AI can shoulder administrative burdens and deliver customized lessons, freeing educators to focus on what humans do best: fostering connection, creativity, and character.
And yes, schools will endure—not just as childcare centers but as spaces where kids learn to navigate friendships, resolve conflicts, and discover their place in the world. The future of education isn’t a choice between humans and machines. It’s about leveraging both to build smarter, more compassionate learners.
So, the next time your kid practices French on Duolingo, remember: That friendly owl mascot might be their AI tutor, but their classroom teacher remains the irreplaceable guide helping them soar beyond the screen.
