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

The next significant milestone for crypto is emerging from advancements in artificial intelligence, according to Joseph Lubin, CEO of Consensys and Ethereum co-founder. He noted that autonomous or semi-autonomous agents can conduct transactions, coordinate, and verify each other on decentralized networks, utilizing crypto infrastructure as the foundation for machine-driven activities. Lubin, set to speak at Consensus Miami 2026, expressed sympathy for the idea that blockchain is suited for machine intelligences but does not foresee humans being replaced. Instead, increasingly intelligent interfaces will simplify complexity, allowing users to interact with crypto systems through intent rather than manual inputs, with AI serving as the intermediary layer between people and protocols. This vision, however, comes with risks, as concentrated AI infrastructure among large tech firms could pose significant problems. Lubin emphasized the importance of decentralized systems and cryptography in ensuring accountability and enabling machines to verify each other in transparent environments. Products like MetaMask are evolving to reflect this shift, with Lubin describing the wallet 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. The rise of corporate chains on Ethereum is also expected, with Lubin anticipating that companies will seek higher throughput and greater control over their infrastructure. He believes assets are best issued on Ethereum's base layer to ensure durability. Stablecoins are seen as a stepping stone toward more decentralized financial systems, and tokenization is expected to bring traditional and decentralized finance closer together, resulting in a more granular and programmable global economy. Lubin adopted a measured tone regarding long-term technical risks like quantum computing, stating that Ethereum developers have been preparing for years and view it as part of the natural evolution of Ethereum.
