The internet has become deeply woven into modern life, shaping how people work, communicate, and access vital services. As society places more trust in technology, Ethereum co-founder Vitalik Buterin warns that many critical systems are being built in closed, centralised ways. When trust is compromised by hidden flaws or vulnerabilities, people may fall back on personal connections or familiar institutions. Buterin emphasises that sectors such as healthcare, finance, and governance should adopt open-source and verifiable models, with verification accessible not just to experts but to everyday users.
