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

The next significant milestone for crypto is expected to come from advancements in artificial intelligence, according to Joseph Lubin, co-founder of Ethereum and CEO of Consensys. In a recent interview, Lubin expressed his belief that autonomous agents can facilitate transactions, coordination, and verification on decentralized networks, leveraging crypto infrastructure for machine-driven activities. He will be sharing his insights at Consensus Miami 2026. Lubin envisions a future where increasingly intelligent interfaces simplify user interactions with crypto systems, allowing people to engage with protocols through intent rather than manual inputs, with AI acting as an intermediary layer. However, he warns that if AI infrastructure remains controlled by a few large tech firms, it could pose significant risks. Decentralized systems and cryptography will be crucial in ensuring accountability and enabling transparent, verifiable environments. Products like MetaMask are being revamped 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 decentralized economy on behalf of users. The rise of corporate chains on Ethereum is another significant trend, with Lubin expecting companies to seek higher throughput and greater control over their infrastructure. He emphasizes that assets are best issued on Ethereum's base layer to ensure durability. Stablecoins are seen as a stepping stone toward more decentralized financial systems, with growth in decentralized collateral expected to enable more robust, crypto-native forms of money. Lubin also discusses the convergence of traditional and decentralized finance, resulting in a more granular and programmable global economy. While acknowledging the potential risks of quantum computing, Lubin adopts a measured tone, stating that Ethereum developers have been preparing for this eventuality and see it as part of the natural evolution of the platform.
