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

According to Consensys CEO and Ethereum co-founder Joseph Lubin, the next significant milestone in the crypto space will be driven by artificial intelligence. In a conversation with CoinDesk, Lubin noted that autonomous agents can facilitate transactions, coordination, and verification on decentralized networks, leveraging crypto infrastructure 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 he does not envision humans being replaced. Instead, he predicts that increasingly intelligent interfaces will simplify complexity, enabling users to interact with crypto systems through intent rather than manual inputs, with AI serving as the intermediary layer between people and protocols. However, this vision also comes with risks, as Lubin warned that if AI infrastructure remains concentrated among a few large technology firms, it could lead to trouble. He emphasized the importance of decentralized systems and cryptography in ensuring accountability, allowing 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 type of neobank that users own and control, part of a transition toward a personal money operating system. AI-powered agents could act on behalf of users, managing assets and executing transactions within a growing decentralized economy. Lubin also discussed the rise of corporate chains on Ethereum, expecting companies to seek higher throughput and greater control over their infrastructure. He believes that assets are best issued on Ethereum's base layer, as it ensures durability. Stablecoins, a rapidly growing sector, are part of this transition but not the ultimate goal. Lubin views them as a stepping stone toward more fully decentralized financial systems, noting that current models rely heavily on centralized issuers. Over time, he expects growth in decentralized collateral to enable more robust, crypto-native forms of money. Regarding tokenization, Lubin suggested that traditional finance and decentralized finance are converging, combining centuries of financial innovation with newer blockchain-based systems. This convergence will 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 view it as a natural part of the network's evolution.
