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

According to Joseph Lubin, the CEO of Consensys and co-founder of Ethereum, the next significant milestone in the crypto space will be driven by artificial intelligence. In a conversation with CoinDesk, Lubin noted that autonomous agents can perform transactions, coordinate, and verify each other on decentralized networks, leveraging crypto infrastructure 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 he does not envision humans being replaced. Instead, he predicted that 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, this vision also comes with risks, as Lubin warned that if AI infrastructure remains concentrated among a few large tech firms, it could lead to trouble. He 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 the wallet as being rebuilt into a 'new kind of neobank that you 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 pointed to structural changes within the Ethereum ecosystem, including the rise of 'corporate chains' 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, even if they are later used across other networks. Stablecoins, a rapidly growing sector in crypto, are part of this transition but not the ultimate goal. Lubin views them as a 'stepping stone' toward more fully decentralized financial systems, noting that current models rely heavily on centralized issuers. Over time, he 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 will result in a more granular and programmable global economy. While addressing longer-term technical risks like quantum computing, Lubin adopted a measured tone, stating that Ethereum developers have been preparing for years and see it as part of the natural evolution of Ethereum.
