Vitalik Buterin, the founder of Ethereum, stated on X platform that his thinking about governance mechanisms has undergone a significant change. He had previously attempted to design a mathematically proven optimal governance mechanism, but found certain fundamental impossibilities, and the success or failure of the system depends on the degree of coordination between participants and unmodelable "culture" factors. He admitted that mathematics and economics were important tools for his understanding of the world, but their role has weakened, and he now tends to roughly predict the operation of social mechanisms rather than pursue perfect explanations.
