Vitalik Buterin, the co-founder of Ethereum, has outlined his vision for a "self-sovereign" technology setup by 2026. In this plan, he suggests replacing Big Tech applications with encrypted, open-source, and locally-based privacy tools. By emphasizing privacy and openness, Buterin aims to create a more secure and user-controlled online environment. This initiative reflects a growing trend towards decentralization and individual empowerment in the tech industry.
