Ethereum must evolve to ensure its long-term viability, according to Buterin. Key improvements include quantum resistance to protect against future computing threats and a scalable architecture to handle increasing transaction volumes. A better block-building model is also needed to resist centralization. These changes are critical for Ethereum to pass the 'walkaway test' and remain relevant for the next 100 years, ensuring its continued success and adoption in the decentralized landscape.
