Jack Dorsey

Jack Dorsey fascinates me because he keeps building things that outgrow him. Co-founding Twitter reshaped how the world argues in public, and then he went and did it again with Block, rewiring how ordinary people move money through Square and Cash App. What interests me now is the philosophy: his pivot toward Bitcoin and the decentralized Bluesky reads like a man uneasy with the very centralized power he once created. The fasting, the meditation, the monk-like minimalism, all of it suggests someone wrestling with the consequences of his own inventions. Love him or find him maddening, he is one of the few founders genuinely trying to give control back.
