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 turning point in the crypto industry will be driven by artificial intelligence. In a recent interview, Lubin noted that autonomous agents can perform transactions, coordinate, and verify each other on decentralized networks, leveraging 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 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 acting as an intermediary layer between people and protocols. However, this vision also carries risks, particularly if AI infrastructure remains controlled by a few large tech firms, which could lead to trouble, according to Lubin. He emphasized the importance of decentralized systems and cryptography in ensuring accountability and enabling machines to verify each other in transparent environments. As part of this shift, products like MetaMask are evolving. Lubin described the wallet as being rebuilt as a "new kind of neobank that you own and control," marking a transition toward a personal financial operating system. AI-powered agents could manage assets, execute transactions, and navigate the growing decentralized economy on behalf of users. 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, even if they are later used across other networks. Stablecoins are part of this transition but not the endpoint, according to Lubin. He views them as a stepping stone toward more fully decentralized financial systems, noting that current models rely heavily on centralized issuers. Over time, he expects growth in decentralized collateral to enable more robust, crypto-native forms of money. Regarding tokenization, Lubin suggested that traditional finance and decentralized finance are converging, combining centuries of financial innovation with newer blockchain-based systems. This convergence is expected to result in 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.
