Ethereum Co-Founder Joseph Lubin Sounds Alarm on AI Control by Tech Giants

The next significant turning point for crypto is emerging from artificial intelligence, according to Consensys CEO and Ethereum co-founder Joseph Lubin. He notes that autonomous agents can transact and verify each other on decentralized networks, building upon crypto foundations for machine-driven activities. Lubin, set to speak at Consensus Miami 2026, is sympathetic to blockchain being used for machine intelligences but doesn't foresee humans being replaced. Instead, intelligent interfaces will simplify complexity, allowing users to interact with crypto through intent rather than manual inputs, positioning AI as an intermediary between people and protocols. However, if AI infrastructure remains concentrated among a few large tech firms, it could pose significant risks. Decentralized systems and cryptography are crucial for ensuring accountability and enabling machines to verify each other's actions transparently. Reflecting this shift, products like MetaMask are being revamped as user-controlled, AI-powered neobanks. AI agents could manage assets, execute transactions, and navigate the decentralized economy on behalf of users, essentially creating a personal financial system. Beyond interfaces, structural changes in the Ethereum ecosystem are anticipated, including the rise of corporate chains for higher throughput and control. Lubin advocates for issuing assets on Ethereum's base layer for durability, even if they're used across other networks. Stablecoins are seen as a stepping stone toward fully decentralized financial systems, with growth in decentralized collateral expected to enable more robust forms of crypto-native money. Tokenization is expected to converge traditional and decentralized finance, creating a more granular and programmable global economy. Despite these shifts, Lubin remains measured on technical risks like quantum computing, believing Ethereum developers have been preparing and see it as part of the natural evolution of Ethereum.
