In 2009, the Guatemalan computer scientist Luis von Ahn sold his company reCAPTCHA to Google for a sum that he said was sufficient to insure that neither he nor his future children would ever need to work. He briefly considered retirement. “But only for a second,” he told @carina.chocano. “I get really bored.” Instead, he began a new project, Duolingo, which is now the most downloaded education app in the world. He envisioned it as a Web site that would help people learn foreign languages while simultaneously using their work to translate online texts. It evolved into something else, a smartphone app that offers language lessons as a series of bright, colorful, addictive games. Like all of the work von Ahn is known for, the program is an investigation into not only what we can learn from machines but also into what machines can learn from us.

Last September, Duolingo got a sneak preview of GPT-4 and decided that the large-language model will create much of its content going forward. Artificial intelligence will eventually make computers better teachers than people, von Ahn said. He sees this as a positive development, since more people have access to smartphones than to high-quality education. “We’ve all gone to school,” he said. “Some teachers are good, but the vast majority are not all that great. . . . And I really want people to be able to learn for free.” At the link in our bio, read a Profile of the founder of Duolingo. Photograph by Luis Corzo (@cor.zo) for The New Yorker.
