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 milestone in the crypto industry will be driven by artificial intelligence. In a recent interview, Lubin emphasized that autonomous agents can facilitate transactions, coordination, and verification on decentralized networks, leveraging crypto infrastructure for machine-driven activities. Lubin, who is set to speak at Consensus Miami 2026, expressed his support for the idea that blockchain technology is suitable for machine intelligences. However, he believes that humans will not be replaced, and instead, increasingly intelligent interfaces will simplify complexity, allowing users to interact with crypto systems through intent rather than manual inputs. In this model, AI serves as an intermediary layer between people and protocols. This vision also comes with potential risks. If AI infrastructure remains concentrated among a few large technology firms, it could lead to trouble, Lubin warned. He argued that decentralized systems and cryptography are crucial in ensuring accountability and enabling machines to verify each other's actions in transparent environments. The evolution of products like MetaMask reflects this shift. Lubin stated that the wallet is being rebuilt as a new type of neobank that users own and control, marking a transition toward a personal money operating system. AI-powered agents can act on behalf of users, managing assets, executing transactions, and navigating the growing decentralized economy. As Lubin noted, users can essentially carry their personal financial system in their pocket. The rise of corporate chains on the Ethereum blockchain is another significant development. Lubin pointed to structural changes in the Ethereum ecosystem, where the blockchain's architecture is influencing how institutions approach adoption. He expects corporate chains to become more common as companies seek higher throughput and greater control over their infrastructure. Despite this, Lubin believes that assets are best issued on Ethereum's base layer, as it ensures the asset's durability, even if it is later used across other networks. Stablecoins, a rapidly growing sector in crypto, are part of this transition but not the ultimate goal. Lubin described them as a stepping stone toward more fully decentralized financial systems, noting that current models rely heavily on centralized issuers. Over time, he expects the growth of 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 will result in a more granular and programmable global economy. When addressing longer-term technical risks like quantum computing, Lubin adopted a measured tone. While it is not an immediate concern, he stated that Ethereum developers have been preparing for years and view it as part of the natural evolution of Ethereum.
