Ethereum Co-Founder Joseph Lubin Highlights the Risks of AI Dominance by Big Tech

The next significant development in the crypto space is expected to come from advancements in artificial intelligence, according to Joseph Lubin, the CEO of Consensys and co-founder of Ethereum. Lubin shared his insights with CoinDesk, stating that autonomous agents will be able to transact, coordinate, and verify each other on decentralized networks, utilizing crypto as the foundation for machine-driven activities. He will be speaking at Consensus Miami 2026 next month. Lubin expressed his support for the idea that blockchain technology is suited for machine intelligences but emphasized that humans will not be replaced. Instead, increasingly intelligent interfaces will simplify complexity, allowing users to interact with crypto systems through intent rather than manual inputs, with AI acting as an intermediary layer between people and protocols. However, if AI infrastructure remains controlled by a few large technology firms, it could pose significant risks. Lubin warned that decentralized systems and cryptography will be crucial in ensuring accountability and enabling machines to verify each other in transparent environments. Products like MetaMask are evolving to reflect this shift, with Lubin describing it as a new kind of neobank that users 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. Lubin also pointed to structural changes in the Ethereum ecosystem, including the rise of corporate chains, which he expects to become more common as companies 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 are part of this transition but not the endpoint, serving as a stepping stone toward more fully decentralized financial systems. Lubin described them as heavily reliant on centralized issuers and 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 to create a more granular and programmable global economy. Lubin also addressed the technical risks associated with quantum computing, stating that while it is not an immediate concern, Ethereum developers have been preparing for years and see it as part of the natural evolution of Ethereum.
