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

According to Joseph Lubin, CEO of Consensys and Ethereum co-founder, the next significant development in the crypto space will be driven by artificial intelligence. In a recent interview, Lubin stated that autonomous agents can facilitate transactions, coordination, and verification on decentralized networks, leveraging crypto as the foundation for machine-driven activities. Lubin, who is set to speak at Consensus Miami 2026, expressed his support for the idea that blockchain technology is suited for machine intelligences, but emphasized that this does not mean humans will be replaced. Instead, increasingly intelligent interfaces will simplify complexity, allowing 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 concentrated among a few large tech firms, it could pose significant risks. He stressed that decentralized systems and cryptography are crucial for ensuring accountability and enabling machines to operate in transparent, verifiable environments. The evolution of products like MetaMask, a Consensys product, reflects this shift. Lubin described the wallet as a new type of neobank that users own and control, part of a transition toward a personal money operating system. AI-powered agents could act on behalf of users, managing assets and executing transactions in a growing decentralized economy. Lubin also discussed the rise of corporate chains on Ethereum, expecting companies to 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 in crypto, are seen as 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, Lubin suggested that traditional finance and decentralized finance are converging, combining centuries of financial innovation with newer blockchain-based systems. This convergence is expected to result in a more granular and programmable global economy. While acknowledging the potential risks of quantum computing, Lubin adopted a measured tone, stating that Ethereum developers have been preparing for this challenge for years and see it as part of the natural evolution of Ethereum.
