[Vitalik Buterin Reflects on Ethereum's Failure to Address Key Social Issues] Vitalik Buterin publicly reflected on Ethereum's absence in addressing social issues and proposed the framework of 'shelter technology.' He pointed out that Ethereum's contributions in areas such as freedom, privacy, and digital security are limited, calling on the community to build an open-source technology ecosystem to optimize applications like payments, DeFi, and decentralized social networks. This would serve users who truly need shelter technology while collaborating with allies outside the crypto space to jointly advance technological development.
