Ethereum founder Vitalik Buterin stated on the X platform that his approach to governance mechanisms has undergone a significant transformation. He had attempted to design a mathematically proven optimal governance mechanism, but discovered certain fundamental impossibilities, and the success or failure of the system hinges on factors such as the level of coordination among participants and unmodelable 'culture'. He admitted that mathematics and economics were once important tools for understanding the world, but their role has diminished, and he now tends to make rough predictions about the functioning of social mechanisms rather than pursuing perfect explanations.
