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

The next significant turning point for the crypto industry is expected to come from advancements in artificial intelligence. According to Joseph Lubin, CEO of Consensys and co-founder of Ethereum, autonomous and semi-autonomous agents will be able to transact, coordinate, and verify each other on decentralized networks, using crypto as the foundation for machine-driven activities. Lubin, who is set to speak at Consensus Miami 2026, expressed his support for the idea that blockchain technology is suited for machine intelligences, but does not foresee humans being replaced. Instead, he envisions increasingly intelligent interfaces that will simplify complexity, allowing users to interact with crypto systems through intent rather than manual inputs, with AI serving as the intermediary layer between people and protocols. However, this vision also comes with risks, as the concentration of AI infrastructure among large tech firms could lead to trouble. Lubin emphasized the importance of decentralized systems and cryptography in ensuring accountability and enabling machines to verify each other in transparent environments. The evolution of products like MetaMask reflects this shift, with the wallet being rebuilt as a user-owned and controlled neobank, part of a transition toward a personal money operating system. AI-powered agents could act on behalf of users, managing assets and executing transactions in a growing decentralized economy. The rise of corporate chains on Ethereum is also expected, with companies seeking higher throughput and greater control over their infrastructure. Lubin believes that assets are best issued on Ethereum's base layer to ensure durability, even if they are later used across other networks. Stablecoins are seen as a stepping stone toward more fully decentralized financial systems, with current models relying heavily on centralized issuers. Over time, Lubin expects growth in decentralized collateral to enable more robust, crypto-native forms of money. The convergence of traditional finance and decentralized finance is also expected, combining centuries of financial innovation with newer blockchain-based systems to create a more granular and programmable global economy. While Lubin acknowledges the technical risks associated with quantum computing, he struck a measured tone, stating that Ethereum developers have been preparing for years and see it as part of the natural evolution of the Ethereum ecosystem.
