• Examines world model implementations — AI systems designed to replace management judgment — across three distinct architectural approaches with documented failure modes.
• Core finding: world models fail at the judgment layer; they can route information and even synthesise sense-making, but cannot hold accountability or adapt to contextually novel situations.
• Block’s restructuring created a capability vacuum that AI systems were architecturally unable to fill, not just inadequately trained for.
• Practical takeaway: before removing human roles, decompose what those roles actually do — world model capability maps poorly onto management functions as traditionally defined.
