AI vs. Human Teachers: Why Schools Aren’t Going Anywhere
In a recent interview, Duolingo CEO Luis von Ahn made a provocative claim: artificial intelligence can outperform human teachers in certain aspects of education. But he also added a crucial caveat—schools aren’t disappearing anytime soon. Why? “Because you still need childcare,” he quipped. This statement has reignited debates about the role of technology in education and whether classrooms will remain relevant in an AI-driven world. Let’s unpack what this means for students, parents, and the future of learning.

The Rise of AI as a Personalized Tutor
Von Ahn’s confidence in AI stems from his company’s own success. Duolingo, a language-learning app used by over 500 million people, relies heavily on algorithms to tailor lessons to individual users. The app adjusts difficulty levels in real time, identifies weak spots (like verb conjugations or vocabulary gaps), and even uses chatbots to simulate conversations. According to von Ahn, this level of personalization is something human teachers struggle to replicate in crowded classrooms.
“Imagine a teacher trying to customize lesson plans for 30 students simultaneously,” he said. “Even the most dedicated educator can’t match the precision of an algorithm analyzing millions of data points to predict what a learner needs next.” Studies support this: research from the University of Michigan found that AI tutoring systems can improve test scores by up to 30% compared to traditional instruction, especially in subjects like math and languages.
AI’s advantages don’t stop there. It’s available 24/7, never gets tired, and doesn’t carry biases. For students in underserved communities with limited access to qualified teachers, AI-powered tools could democratize high-quality education. Platforms like Khan Academy and Coursera already use adaptive learning technologies to bridge gaps in global education.

Why Human Teachers Still Matter
But before we declare human educators obsolete, consider this: teaching isn’t just about transferring knowledge. It’s about mentorship, emotional support, and fostering critical thinking—skills machines haven’t mastered. A child struggling with anxiety won’t find solace in a chatbot, and a teen grappling with ethical dilemmas needs guidance no algorithm can provide.
Teachers also play a vital role in socialization. Group projects, debates, and classroom interactions teach collaboration, empathy, and conflict resolution—soft skills essential for adulthood. As psychologist Angela Duckworth notes, “Grit and resilience aren’t learned through screens. They’re forged in real-world challenges, often with a teacher’s encouragement.”
Even von Ahn acknowledges these limitations. “AI excels at delivering content efficiently,” he said. “But humans inspire curiosity, creativity, and a love of learning. That’s irreplaceable.”

The Elephant in the Classroom: Childcare
Now, let’s address von Ahn’s blunt take on why schools will endure: childcare. For many families, schools aren’t just centers of learning—they’re safe, structured environments where kids spend most of their weekday. The pandemic highlighted this dual role. When schools closed, working parents faced impossible choices: juggle jobs while supervising remote learning or risk leaving young children unattended.
This societal function can’t be outsourced to AI. A parent working a 9-to-5 job can’t rely on an app to keep their first-grader engaged (and out of mischief) for eight hours. Schools provide meals, supervision, and extracurricular activities—services that enable parents to participate in the workforce. As von Ahn puts it, “Until robots can babysit, schools aren’t going anywhere.”

The Hybrid Future of Education
The real question isn’t whether AI or humans will dominate education—it’s how they’ll collaborate. Imagine a classroom where AI handles repetitive tasks like grading quizzes or drilling multiplication tables, freeing teachers to focus on mentorship and creative projects. Students might use apps like Duolingo for homework, then discuss cultural nuances with their teacher the next day.
This hybrid model is already taking shape. Tools like ChatGPT assist teachers in creating lesson plans, while AI-powered analytics help identify students at risk of falling behind. Meanwhile, platforms like Outschool combine live virtual classes with human instructors, blending tech efficiency with interpersonal connection.

Preparing for a World of Lifelong Learning
As AI reshapes education, another shift is emerging: the need for lifelong learning. With careers evolving rapidly, adults will increasingly turn to AI-driven platforms to upskill. Duolingo’s CEO envisions a future where people learn new languages or coding skills “on demand” through apps, while schools focus on foundational knowledge and social development.
But this future requires careful navigation. Over-reliance on AI risks widening inequality if marginalized communities lack access to technology. It also raises ethical questions: Who controls the data collected by educational apps? How do we prevent algorithmic biases?

Conclusion
Luis von Ahn’s comments reflect a broader truth: AI is a powerful tool, but not a panacea. It can democratize education and personalize learning at scale, yet it can’t replicate the human touch that nurtures well-rounded individuals. And while schools may evolve—incorporating more technology or flexible schedules—their role as community anchors seems secure.
In the end, the ideal education system might resemble a symphony, not a solo performance. AI handles the technical precision, while humans provide the warmth, wisdom, and care that turn information into understanding. And yes, until robots learn to pack lunchboxes and bandage scraped knees, schools will remain where kids grow—not just intellectually, but as human beings.
