He details how large language models have 10x–12x’d course creation, enabled new conversational features like “Video Call with Lily,” and reshaped engineering, customer support, and content workflows. The conversation digs into retention and motivation as Duolingo’s true moat, the future of CS careers and AGI, and how AI may alter education, work, and societal structures. Hacker also reflects on building Duolingo outside Silicon Valley, fundraising dynamics, Europe’s challenges, and his evolving role, leadership style, and relationship with money and purpose.
