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

According to Joseph Lubin, CEO of Consensys and co-founder of Ethereum, the next significant milestone in the crypto space will be driven by artificial intelligence. In a recent interview, Lubin noted that autonomous agents can facilitate transactions, coordinate, and verify each other on decentralized networks, utilizing 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 does not envision humans being replaced. Instead, he predicts that increasingly sophisticated interfaces will simplify complexities, enabling users to interact with crypto systems through intent rather than manual inputs, with AI acting as an intermediary between people and protocols. However, if AI infrastructure remains concentrated among a few large tech firms, it could pose significant risks. Lubin 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 MetaMask 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. Lubin also discussed the rise of corporate chains on Ethereum, expecting companies to seek higher throughput and greater control over their infrastructure. He believes that assets are best issued on Ethereum's base layer to ensure durability. Stablecoins are part of this transition but not the ultimate goal, as they are currently 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 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 view it as part of the natural evolution of Ethereum.
