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

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. Lubin shared his insights in an interview with CoinDesk, emphasizing that autonomous agents can interact, coordinate, and verify transactions on decentralized networks, leveraging crypto infrastructure for machine-driven activities. He expressed sympathy for the idea that blockchain technology is suited for machine intelligences but does not foresee humans being replaced. Instead, increasingly sophisticated interfaces will simplify complexity, enabling users to interact with crypto systems through intent rather than manual inputs, with AI serving as an intermediary layer between people and protocols. However, Lubin warned that if AI infrastructure remains dominated by large tech firms, it could pose significant risks. He stressed the importance of decentralized systems and cryptography in ensuring accountability and enabling transparent, verifiable environments where machines can 'check on one another.' The evolution of products like MetaMask reflects this broader shift. Lubin described MetaMask as being rebuilt into 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 a growing decentralized economy on behalf of users. Lubin also discussed the rise of 'corporate chains' on Ethereum, where 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, a rapidly growing sector, are seen as a 'stepping stone' toward more fully decentralized financial systems, with current models still reliant on centralized issuers. Over time, Lubin 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 centuries of financial innovation with newer blockchain-based systems to create a more granular and programmable global economy. Lubin also addressed concerns about quantum computing, stating that while it is not an immediate concern, Ethereum developers have been preparing for years and see it as part of the natural evolution of Ethereum.
