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 space will be driven by artificial intelligence. In an interview, Lubin stated that autonomous agents can facilitate transactions, coordination, and verification on decentralized networks, leveraging crypto infrastructure for machine-driven activities. He expressed support for the idea that blockchain technology is suited for machine intelligence but does not envision 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 between people and protocols. However, if AI infrastructure remains concentrated among a few large tech firms, it could pose significant risks. 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-controlled neobank, part of 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 discussed the rise of corporate chains on Ethereum, expecting companies to seek higher throughput and greater control over their infrastructure. He argued that assets are best issued on Ethereum's base layer to ensure durability. Stablecoins, although part of the transition, are not the endpoint, but rather a stepping stone toward more fully decentralized financial systems. 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, resulting in 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.
