Ethereum Co-Founder Joseph Lubin Highlights the Risks of AI Control by Major Tech Firms

According to Joseph Lubin, the upcoming significant turning point in the crypto space will be driven by artificial intelligence. Lubin, who is set to speak at Consensus Miami 2026, emphasized that autonomous or semi-autonomous agents can facilitate transactions, coordinate, and verify each other on decentralized networks, utilizing crypto as the foundation for machine-driven activities. He expressed sympathy for the idea that blockchain is suited for machine intelligences but does not foresee humans being replaced. Instead, increasingly intelligent interfaces will simplify complexity, enabling users to interact with crypto systems through intent rather than manual inputs, with AI serving as the intermediary layer between people and protocols. However, if AI infrastructure remains concentrated among large tech firms, it could pose significant risks. Lubin warned that decentralized systems and cryptography are crucial in ensuring accountability, allowing machines to verify each other in transparent environments. The evolution of products like MetaMask, a Consensys product, reflects this shift. Lubin described the wallet as a new kind of neobank that users own and control, part of a transition toward a personal money operating system. AI-powered agents could act on behalf of users, managing assets and executing transactions within a growing decentralized economy. Lubin also pointed to structural changes in the Ethereum ecosystem, including the rise of corporate chains, which are expected to become more common as companies seek higher throughput and greater control over their infrastructure. He emphasized that assets are best issued on Ethereum's base layer to ensure durability. Stablecoins are part of this transition but not the endpoint, serving as a stepping stone toward more decentralized financial systems. Lubin described traditional finance and decentralized finance as converging, combining centuries of financial innovation with newer blockchain-based systems, resulting in a more granular and programmable global economy. While addressing longer-term technical risks like quantum computing, Lubin struck a measured tone, stating that Ethereum developers have been preparing for years and see it as part of the natural evolution of Ethereum.
