Duolingo is no stranger to disruption. But when CEO Luis von Ahn announced a bold plan to become an “AI-first” company earlier this year, he likely didn’t anticipate the fierce backlash it would unleash, not from competitors, but from the very human experts the platform once relied on.
As the language learning giant ramps up its use of artificial intelligence to personalize lessons, simulate real conversations, and replace some instructor-written content, a wave of criticism has emerged from users, educators, and even employees. The concern? That in its push for efficiency, Duolingo may be losing the soul of its product.
A Pivot to AI-First, With Real Consequences
Duolingo’s transformation is part of a broader strategy to leverage generative AI for deeper personalization and cost savings. The company has already rolled out GPT-powered features that simulate language tutors and fine-tune lesson paths.
CEO von Ahn positioned this shift as the future of education. “Our goal is to make high-quality education free and accessible for everyone, and AI can scale that mission better than any human workforce,” he said in a recent interview.
But the changes didn’t sit well with everyone.
The Human Educators Push Back
Duolingo quietly laid off a significant number of contractors, many of them language experts who had written and reviewed lessons for years. As mentioned by Millionaire MNL, some of these workers took to social media to call out the move, accusing the company of “replacing expertise with chatbots.”
Critics say AI-generated lessons may lack cultural nuance, pedagogical insight, or even basic accuracy in less commonly spoken languages. “It’s a disservice to learners,” one former language consultant said. “Fluency isn’t just grammar—it’s human context.”
Users Are Noticing, Too
It’s not just the educators who are upset. A vocal segment of Duolingo’s 80 million monthly users say the new AI-generated lessons feel less polished or more robotic. Reviews in app stores and Reddit threads point to strange translations and buggy behavior in newer AI modules.
Still, Duolingo’s leadership is doubling down.
Why von Ahn Won’t Hit Pause
For Duolingo, the upside is clear. AI drastically reduces the cost of content production and opens the door to new verticals, from math to music to professional certifications. Internally, the company sees AI as the engine of its next phase of growth.
Despite the backlash, von Ahn remains confident that quality will improve as the models evolve. “This is just the beginning,” he told investors. “We’re building something that’s going to change how people learn, full stop.”
The Bigger Question: What Happens to Human Expertise?
Duolingo’s pivot is part of a larger conversation happening across the edtech world: What’s the right balance between automation and human knowledge?
Some platforms, like Khan Academy and Coursera, are experimenting with AI as a supplement, not a replacement. Others are leaning into the idea that AI can be better, faster, and cheaper than humans. Duolingo is clearly in the latter camp.
Whether that gamble pays off, or alienates its core audience, remains to be seen.
