Ethereum Co-Founder Joseph Lubin Highlights the Risks of AI Control by Major Tech Companies

The next significant milestone in the crypto space is expected to emerge from advancements in artificial intelligence, according to Joseph Lubin, the CEO of Consensys and co-founder of Ethereum. He emphasized that autonomous agents can interact, coordinate, and verify each other on decentralized networks, utilizing crypto 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 foresee humans being replaced. Instead, he envisions increasingly intelligent interfaces simplifying complexity, allowing users to interact with crypto systems through intent rather than manual inputs, with AI serving as an intermediary between people and protocols. However, this vision also carries risks, as Lubin warned that if AI infrastructure remains concentrated among a few large tech firms, it could lead to trouble. He stressed 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 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 a growing decentralized economy on behalf of users. The rise of corporate chains on Ethereum is another significant development, with Lubin expecting companies to 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, a rapidly growing sector, are a stepping stone toward more decentralized financial systems, but not the endpoint. 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. This convergence is expected to 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.
