Vitalik Buterin, the founder of Ethereum, said on the X platform that his way of thinking about governance mechanisms has undergone a major shift. He tried to design a governance mechanism that was mathematically optimal, but found some fundamental impossibilities, and the key to the success or failure of the system was the degree of coordination among the participants and the "culture" that could not be modeled. He admitted that mathematics and economics, once important tools for understanding the world, are now less useful, and more inclined to roughly predict the operation of social mechanisms rather than pursue perfect explanations.
