Esther Dyson is a Swiss-American technology investor, author, and former journalist whose career has spanned five decades and multiple reinventions - from fact-checker at Forbes to the founding chair of ICANN, from running the most influential tech conference of the 1990s to training as a backup cosmonaut in Star City, Russia. The daughter of physicist Freeman Dyson, she built EDventure Holdings and its newsletter Release 1.0 into required reading for Silicon Valley's elite before pivoting to angel investing in health tech, AI, and aerospace. Now working on her book 'Term Limits: Time and Scale in the Age of AI' (MIT Press, 2027), she remains one of tech's most original and independent thinkers, guided by her personal motto: 'Always make new mistakes.'
