Interview with Luis von Ahn. Describes the development of CAPTCHA to distinguish humans from bots signing up to Yahoo!; the development of reCAPTCHA to distinguish humans from bots whilst simultaneously digitising books; the development of Duolingo, a language learning app; and the iteration to find a sustainable business model for Duolingo.
