Ethereum Co-Founder Joseph Lubin Warns of AI Control by Big Tech Firms

The cryptocurrency space is on the cusp of a significant transformation driven by artificial intelligence, according to Joseph Lubin, the co-founder of Ethereum and CEO of Consensys. In a recent conversation with CoinDesk, Lubin emphasized the potential of autonomous agents to facilitate transactions, coordination, and verification on decentralized networks, leveraging crypto infrastructure as the foundation for machine-driven activities. He expressed his support for the idea that blockchain technology is suited for machine intelligences but does not anticipate humans being replaced. Instead, he envisions increasingly intelligent interfaces that 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, Lubin cautioned that if AI infrastructure remains concentrated among a few large tech firms, it could pose significant risks. He stressed the importance of decentralized systems and cryptography in ensuring accountability and enabling machines to operate transparently and verifiably. 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 manage assets, execute transactions, and navigate the growing decentralized economy on behalf of users. Lubin also discussed the rise of corporate chains on Ethereum, expecting companies to seek higher throughput and greater control over their infrastructure. He emphasized the importance of issuing assets on Ethereum's base layer for durability. Stablecoins, while part of the transition, are not the endpoint but rather a stepping stone toward more fully decentralized financial systems. Lubin noted that current models rely heavily on centralized issuers but expects growth in decentralized collateral to enable more robust, crypto-native forms of money. On tokenization, he suggested that traditional finance and decentralized finance are converging, combining financial innovation with blockchain-based systems to create a more granular and programmable global economy. Regarding longer-term technical risks like quantum computing, Lubin adopted a measured tone, stating that Ethereum developers have been preparing for years and see it as part of the natural evolution of Ethereum.
