Two of the graduate students who passed through that MIT group, Casey Reas and Ben Fry, built on Design By Numbers to create the open-source language Processing in 2001, extending its minimalist approach beyond the fixed canvas and grayscale limits of Maeda's tool and influencing a generation of generative artists.^3,5 Maeda named the Processing project's later leaders — Casey Reas, Ben Fry, Dan Shiffman and Lauren Lee McCarthy — as the people who carried computational design and art forward into the current century.² He served as the sixteenth president of the Rhode Island School of Design from 2008 to 2014, having previously been associate director of research at the MIT Media Lab.^1,4

His art has been included in solo exhibitions such as “John Maeda: NATURE” at the Fondation Cartier in Paris.^1,6 It is also held in the permanent collections of the Museum of Modern Art in New York and the Cartier Foundation.¹ He has written several books, including The Laws of Simplicity and, in 2019, How to Speak Machine.^1,7 The latter argued that computation is less something mastered in a coding boot camp than “a foreign country”.⁷

In 2024 he was invited to co-curate “Awaken, Metamagical Hands” at Gazelli Art House in London, an exhibition of early generative art practitioners including Joshua Davis, Golan Levin, LIA and Lauren Lee McCarthy that paired physical prints with NFT certificates of authenticity. The show's title traces back to a poem Maeda wrote in an early-1990s booklet called Design Machines, imagining a world in which computers could be used as if they had “metamagical hands” that never got tired.⁶ He showed his AI Infinity in the exhibition,⁶ a 1992 work first shown at Kate Vass Galerie's “Automat und Mensch” show in Zürich in 2019.⁸ He has served as vice president of AI and design at Microsoft.^1,6
