Summary

The most directly relevant cautionary tale for a language-learning company: Duolingo’s April 2025 AI-first memo (replace contractor content work with AI, automate before hiring) triggered boycott calls, mass unfollows, and measurably slower DAU growth (40% YoY vs 60% prior year, concentrated among younger US/Canada users). CEO Luis von Ahn conceded he ‘didn’t give enough context’. Experts locate the failure in framing AI as replacing humans rather than benefiting learners.
