Jack Dorsey's New Long Read: Using AI to Replace Hierarchical Coordination, Reshaping Human Organizational Structure

On March 31, Twitter co-founders Jack Dorsey and Roelof Botha published a lengthy article titled *From Hierarchy to Intelligence*, outlining that AI-powered replacement of human hierarchical coordination will emerge as a common pattern for future organizations—ending a 2,000-year reliance on hierarchy. Core points include: - Organizational design has relied on hierarchy for over 2,000 years. Rooted in military and industrial eras, this structure is limited by humans’ “span of control”—typically just 3 to 8 people managed effectively. - Hierarchy functions as an information routing protocol, but more layers mean slower information flow and decision-making. - Block aims to fully replace human hierarchical coordination with AI, shifting companies from “hierarchical organizations” to “entities built as intelligent beings.” - Value will shift from hierarchy to intelligence: human roles move to the “edge,” focused on engaging with reality, intuition, and ethics, while AI handles coordination, alignment, and proactive decision-making. To replace middle management, Block plans to build two core AI-powered world models: - **Company World Model**: Leverages decision records, code, documents, and other assets from remote work to let AI continuously track the company’s internal operations. - **Customer World Model**: Uses real transaction data from Cash App, Square, and other Block services (Block views money as the most honest signal) to develop a deep understanding of customers’ true financial situations. With an intelligent layer built on these models, the system can proactively combine underlying financial capabilities to deliver predictive solutions to customers.
