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

According to Consensys CEO and Ethereum co-founder Joseph Lubin, the next significant turning point for crypto is approaching, driven by advancements in artificial intelligence. In a recent conversation with CoinDesk, Lubin emphasized the potential of autonomous or semi-autonomous agents to engage in transactions, coordinate, and verify each other on decentralized networks, utilizing crypto as the foundation for machine-driven activities. He expressed sympathy for the idea that blockchain is suited for machine intelligences but does not foresee humans being replaced. Instead, increasingly sophisticated interfaces will simplify complexity, allowing users to interact with crypto systems through intent rather than manual inputs, positioning AI as an intermediary layer between people and protocols. However, Lubin cautioned that if AI infrastructure remains concentrated among a few large tech firms, it could pose significant risks. 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, with the wallet being rebuilt as a user-controlled neobank, 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 structural changes in the Ethereum ecosystem, including the rise of corporate chains, which he believes will become more common as companies seek higher throughput and greater control over their infrastructure. While he expects assets to be issued on Ethereum's base layer for durability, he noted that stablecoins are a stepping stone toward more decentralized financial systems. On tokenization, Lubin suggested that traditional and decentralized finance are converging, combining centuries of financial innovation with newer blockchain-based systems, resulting in a more granular and programmable global economy. Despite these shifts, Lubin adopted a measured tone on longer-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.
