Part I — The story
The story
Sam Altman became the defining business figure of the artificial-intelligence era as CEO of OpenAI, the lab behind ChatGPT that pushed AI from research curiosity into a technology used by hundreds of millions. He had already shaped a generation of startups as president of Y Combinator before turning to what he considers the most important technology in history.
Altman's bet is audacious: that artificial general intelligence — systems as capable as humans across most tasks — can be built within our lifetimes, and that doing so safely and steering its benefits is one of the central challenges of the age. In late 2023 he was briefly removed by OpenAI's board and reinstated within days amid overwhelming support, an episode that underscored his centrality to the field.
As of early 2026 Altman leads OpenAI at the frontier of AI. His career blends startup-ecosystem influence with a conviction that AI will reshape the economy — making him one of the most consequential and closely watched figures in technology.
