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 for cryptocurrency will be driven by artificial intelligence. In a recent interview, Lubin stated that autonomous or semi-autonomous agents will be able to transact, coordinate, and verify each other on decentralized networks, utilizing cryptocurrency as the foundation for machine-driven activities. Lubin, who is set to speak at Consensus Miami 2026, expressed sympathy for the idea that blockchain technology is suited for machine intelligences but does not envision humans being replaced. Instead, he believes that increasingly intelligent interfaces will simplify complexity, allowing users to interact with cryptocurrency systems through intent rather than manual inputs, with AI serving as an intermediary layer between people and protocols. However, if AI infrastructure remains concentrated among a few large technology 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, a Consensys product, reflects this shift. Lubin described MetaMask as a new type of neobank that users own and control, part of a transition toward a personal financial operating system. AI-powered agents could act on behalf of users, managing assets and executing transactions within a growing decentralized economy. 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. While stablecoins are a rapidly growing sector, Lubin views them as a stepping stone toward more fully decentralized financial systems. He expects the growth of decentralized collateral to enable more robust, crypto-native forms of money. Regarding tokenization, Lubin believes 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. Despite the potential risks of quantum computing, Lubin adopted a measured tone, stating that Ethereum developers have been preparing for this eventuality for years and see it as part of the natural evolution of Ethereum.
