Vitalik: Ethereum should stick to its core L1 features while adopting bolder and more open thinking at the application layer Vitalik Buterin shared his thoughts, stating that Ethereum should uphold its core L1 features—censorship resistance, open-source, privacy, and security—while embracing bolder and more open thinking at the application layer. He proposed two extreme scenarios: What if AI causes wallet extensions to disappear within a year? What if the future of DeFi is reduced to a futures market based solely on decentralized oracles? Vitalik believes that with the development of AI, 'applications' are evolving from discrete actions to continuous spaces, and the model of users self-organizing around core functionalities will inevitably expand. He also emphasized that privacy should be as important as other types of security and called for a rethinking of the role of L2s, encouraging developers to break free from path dependency and think from first principles about what should be built.
