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

According to Joseph Lubin, CEO of Consensys and co-founder of Ethereum, the next significant milestone for the crypto industry will be driven by advancements in artificial intelligence. Lubin shared his insights in an interview with CoinDesk, emphasizing the potential of autonomous agents to interact, coordinate, and verify transactions on decentralized networks, leveraging crypto infrastructure for machine-driven activities. He will be speaking at Consensus Miami 2026 next month. Lubin expressed his support for the idea that blockchain technology is suited for machine intelligences but does not foresee humans being replaced. Instead, he believes that increasingly sophisticated interfaces will simplify complexity, enabling users to engage with crypto systems through intent rather than manual inputs, with AI serving as an intermediary layer between people and protocols. However, if AI infrastructure remains concentrated among a few large tech companies, it could pose significant risks. Lubin warned that decentralized systems and cryptography are crucial for ensuring accountability and enabling machines to verify each other's actions in transparent environments. Products like MetaMask are evolving to reflect this shift, with Lubin describing the wallet as a 'new kind of neobank that you 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' 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 ultimate goal, as they remain reliant on centralized issuers. Lubin expects growth in decentralized collateral to enable more robust, crypto-native forms of money. He also discussed the convergence of traditional finance and decentralized finance, combining centuries of financial innovation with newer blockchain-based systems to create a more granular and programmable global economy. While acknowledging the potential risks of quantum computing, Lubin struck a measured tone, stating that Ethereum developers have been preparing for this challenge for years and see it as part of the natural evolution of Ethereum.
