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

According to Consensys CEO and Ethereum Co-Founder Joseph Lubin, the next significant milestone for crypto will be driven by artificial intelligence. In a conversation with CoinDesk, Lubin explained that autonomous or semi-autonomous agents can engage in transactions, coordinate, and verify each other on decentralized networks, utilizing crypto rails 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 is suited for machine intelligences, but does not envision humans being 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 the intermediary layer between people and protocols. However, if AI infrastructure remains concentrated among large tech firms, it could pose significant risks. Lubin emphasized that decentralized systems and cryptography will be crucial in ensuring accountability, enabling machines to verify each other in transparent environments. Products like MetaMask are evolving to reflect this shift, with Lubin describing the wallet as 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 the growing decentralized economy on behalf of users. The rise of corporate chains on Ethereum is also expected, with Lubin predicting that companies will seek higher throughput and greater control over their infrastructure. He believes that assets are best issued on Ethereum's base layer, as it ensures durability. Stablecoins are part of this transition, but not the ultimate goal, as they are still heavily reliant on centralized issuers. Lubin expects growth in decentralized collateral to enable more robust, crypto-native forms of money. The convergence of traditional finance and decentralized finance is also underway, combining centuries of financial innovation with newer blockchain-based systems, resulting in a more granular and programmable global economy. Lubin adopted a measured tone when discussing longer-term technical risks like quantum computing, stating that Ethereum developers have been preparing for years and view it as part of the natural evolution of Ethereum.
