**[Jack Dorsey's New Essay: Using AI to Replace Hierarchical Coordination and Reshape Human Organizational Structures]** BlockBeats News, March 31 — Twitter founder Jack Dorsey and Roelof Botha co-authored a long-form essay titled *"From Hierarchy to Intelligence"*, discussing how replacing human hierarchical coordination with AI will become the prevalent model for future organizations, ending a reliance on hierarchy that has lasted over two millennia. The core points are as follows: For over 2,000 years, organizational design has been built on hierarchical structures (Hierarchy), which originated in the military and industrial eras. These structures are primarily limited by the human "span of control," which typically allows effective management of only 3–8 people. Hierarchy is essentially an "information routing protocol," but as layers increase, it significantly slows down information flow and decision-making. Block is experimenting with using AI to completely replace the function of human hierarchical coordination, transforming the company from a "hierarchical organization" into a "company built as an intelligent agent." Value will shift from hierarchy to intelligence, with human roles pushed to the "edges," responsible for directly facing reality, intuition, and ethics, while AI handles coordination, alignment, and proactive decision-making. Block proposes using AI to construct two key world models to replace middle management: 1. **Company World Model:** Based on various decision records, code, documents, and other outputs generated through remote work, allowing AI to continuously grasp the internal operational state of the company. 2. **Customer World Model:** Based on real transaction data generated by Cash App, Square, and others (Block believes money is the most honest signal), forming a deep understanding of customers' real economic conditions. On this foundation, an intelligent layer can be built that actively integrates underlying financial capabilities to provide predictive solutions for customers.
