Biography
Jack Dorsey emerged from the tech scene of the early 2000s not as a flamboyant CEO, but as a quiet, almost monastic figure fascinated by the flow of information and cities. His idea for Twitter—a service for sharing short, status-update messages—was born from his interest in dispatch systems and the ambient awareness of a city's rhythm. Launched in 2006, it rapidly evolved from a niche tool into a world-altering platform for news, activism, and public conversation, making Dorsey a central, if reluctant, figure in the digital age. His leadership at Twitter was marked by periods of intense growth and equally intense scrutiny over content moderation and the platform's societal impact. Parallel to this, he founded Square (now Block, Inc.), a company that democratized credit card processing for small businesses via a simple smartphone dongle, and later expanded into cryptocurrency and financial services. Dorsey's vision consistently leans towards decentralization and simplicity, a philosophy that later led him to help fund Bluesky, a decentralized social media protocol.
Generation X
1965–1980
The latchkey kids. Raised during divorce, recession, and the end of the Cold War. Skeptical, self-reliant, media-literate. They invented indie culture, grunge, and the early internet — then watched the Boomers take credit.
Jack was born in 1976, placing them squarely in the Generation X. The events that shaped this generation — economic uncertainty, the end of the Cold War, and the rise of personal computing — shaped the world they entered and the choices available to them.
