Why AI Tutors Won’t Replace Schools—But Will Transform Learning
Luis von Ahn, co-founder and CEO of Duolingo, recently made a provocative claim: Artificial intelligence is becoming a better teacher than humans. While this statement might sound like a dystopian headline, von Ahn clarifies that schools aren’t going anywhere—because society still needs them for something far more fundamental than academics. “Schools will exist because you still need childcare,” he quipped. This duality—AI’s growing role in personalized education and schools’ irreplaceable social function—reveals a fascinating tension in the future of learning. Let’s unpack why both statements might be true and what this means for students, parents, and educators.
The Rise of AI as a Teaching Tool
Duolingo, the language-learning app used by over 500 million people, has long relied on AI to adapt lessons to individual users. Its algorithms track mistakes, adjust difficulty in real time, and even predict when learners might quit. “Human teachers can’t monitor 30 students simultaneously at this level of detail,” von Ahn argues. AI tutors eliminate the “one-size-fits-all” approach, offering immediate feedback and infinite patience.
This isn’t just theoretical. Studies show AI-driven platforms boost retention rates by tailoring content to learning styles. A struggling math student might receive visual explanations, while a quick learner skips repetitive drills. AI also democratizes access—high-quality tutoring, once a luxury, becomes available to anyone with a smartphone. In remote villages or underfunded schools, AI bridges gaps that human teachers alone cannot.
The Limits of Human Teachers (and Classrooms)
Traditional education systems face well-documented challenges. Overcrowded classrooms make personalized attention rare. Teachers, already stretched thin by administrative tasks, often lack resources to address diverse student needs. Even the most dedicated educators can’t compete with AI’s 24/7 availability or its ability to analyze terabytes of data to optimize lesson plans.
But von Ahn’s childcare comment highlights a deeper truth: Schools serve purposes beyond instruction. They’re social hubs where children learn teamwork, conflict resolution, and empathy. They provide structure for working parents and meals for food-insecure families. A robot might teach grammar better, but it can’t host a science fair, coach a soccer team, or notice when a child seems withdrawn.
The Hybrid Future of Education
The real transformation lies in blending AI’s efficiency with human mentorship. Imagine classrooms where teachers focus less on lecturing and more on fostering creativity. AI handles repetitive tasks—grading quizzes, drilling vocabulary—while educators guide discussions, inspire curiosity, and address emotional needs. This division of labor could elevate teaching from content delivery to true mentorship.
Duolingo’s own model hints at this balance. While its AI tailors language exercises, human contributors design culturally relevant content. Similarly, schools might use AI to identify students needing extra help, freeing teachers to provide targeted support. “The best education,” von Ahn suggests, “combines scalable technology with irreplaceable human touchpoints.”
Why Resistance Is Natural (and Necessary)
Skepticism about AI in education is healthy. Concerns range from data privacy to overreliance on screens. Will AI perpetuate biases hidden in its training data? Could it reduce human interaction to the point of social stagnation? These risks require vigilant oversight—but they’re not reasons to reject AI outright.
Critically, AI’s success depends on collaboration, not competition, with teachers. Tools like ChatGPT can draft lesson plans or simulate student essays, but they lack the nuance to handle sensitive classroom dynamics. As one teacher tweeted, “AI can explain Macbeth, but it can’t comfort a kid whose dog died.”
The Unchanging Value of “Childcare”
Von Ahn’s quip about schools as childcare underscores their societal role. For centuries, schools have doubled as community anchors—a role that persists even as their academic methods evolve. Working parents rely on school schedules; employers structure hours around this system. AI tutors won’t solve the logistical puzzle of who watches kids during the workday.
But this framing also invites us to reimagine schools. If AI handles baseline instruction, could campuses become innovation labs? Imagine more field trips, maker spaces, and project-based learning. Teachers might have smaller groups, allowing deeper relationships. The “childcare” function could evolve from supervision to curated experiences that build resilience and curiosity.
Preparing for a Collaborative Era
The future isn’t about choosing between humans and machines but leveraging their strengths. Policy changes will be crucial: training teachers to use AI tools, ensuring equitable tech access, and redesigning curricula to emphasize skills AI can’t replicate (critical thinking, collaboration, adaptability).
As von Ahn puts it, “Education isn’t just about information transfer; it’s about preparing people for life.” AI excels at the former, humans at the latter. By merging these capabilities, we might finally create an education system that’s both universally accessible and deeply human—one where every student gets the support of a tireless digital tutor and the guidance of a caring teacher.
In this hybrid model, schools thrive not just as childcare centers but as incubators for well-rounded individuals. The chalkboard might disappear, but the laughter in hallways, the thrill of discovery, and the bonds between mentors and learners will remain—and that’s something no algorithm can replicate.
